PROCESS MONITORING METHOD, APPARATUS, AND SYSTEM

FIELD OF THE TECHNOLOGY

The present disclosure relates to the data processing field, and more specifically, to a process monitoring method, apparatus, and system.

BACKGROUND OF THE DISCLOSURE

For testing a network software system, an existing solution is generally to use a method for analyzing network communications data between a client and a server, and most tools that are used perform the analysis by capturing a communications packet between the client and the server, and furthermore perform the test in a manner of tampering with the data.

However, such an existing technology can only help a tester perform a black-box test, and is feasible in a case in which there is only one process in a background server. However, if multiple processes in the background server jointly complete a request of the client, the tester cannot analyze and test, by using the existing tools, such a logic of invocation between background processes, and cannot perform a further gray-box test.

For a problem that a communications logic between multiple processes cannot be monitored in the existing technology, no effective solution has been put forward currently.

Embodiment 1

According to this embodiment of the present invention, a process monitoring method is provided. As shown in FIG. 1, the method includes the following step S102 to step S108:

S102: Obtain processes of a to-be-tested system and a communications relationship between the processes, where the number of the processes is multiple.

For the obtaining of the processes of the to-be-tested system, all of the processes of the to-be-tested system may be obtained according to a working directory in which the to-be-tested system is located and by using a script language provided by an operating system. For example, the processes of the to-be-tested system are obtained by remotely executing a shell command by using ssh. For the obtaining of the communications relationship between the processes, the communications relationship between the processes may be obtained by remotely executing netstat and ipcm commands by using ssh.

S104: Establish communications channels between the processes according to the obtained communications relationship, that is, establish one communications channel between every two processes that have the communications relationship.

S106: Add a relay communications node connected to each of the communications channels, that is, add the relay communications node as an agent communications node, so that each communications channel communicates by using this added relay communications node.

S108: Monitor data content that flows through the relay communications node, and a data flow direction, to obtain communications data and a communications direction between the processes. The relay communications node is connected to each communications channel, and therefore by monitoring the data content that flows through the relay communications node and the data flow direction, the data content transmitted through the communications channel and a transmission direction may be obtained, that is, the communications data and the communications direction between the processes may be obtained.

For a process monitoring method provided in this embodiment of the present invention, a relay communications node connected to each communications channel between processes is added, so that data content that flows through the relay communications node and a flow direction can be monitored, to obtain communications data transmitted between the processes connected by the communications channel and a transmission direction of the data, and thereby monitoring of a communications logic between the multiple processes of the to-be-tested system is implemented, which solves a technical problem that the communications logic between the multiple processes cannot be monitored in the existing technology, thereby achieving a technical effect of performing a gray-box test on the communications logic between the processes of the to-be-tested system.

Specifically, the monitoring data content that flows through the relay communications node, and a data flow direction, to obtain communications data and a communications direction between the processes includes: monitoring data content of a first process and a second process that flows through the relay communications node, and a data flow direction, to obtain communications data and a communications direction between the first process and the second process, where the first process and the second process are any two processes that have a communications relationship in the multiple processes.

Further, the communications relationship obtained in step S102 includes a communications manner, and in this embodiment of the present invention, the relay communications node connected to each communications channel may be added in the following manner:

First, a first communications manner in which a first process and a second process send data to and receive data from each other is obtained, where the first process and the second process are any two processes that have a communications relationship in the multiple processes.

Next, whether the first communications manner is the same as a second communications manner in which the relay communications node sends and receives data is determined.

In a case in which it is determined that the first communications manner is different from the second communications manner, a connection between the first process and a first conversion process is established, and a connection between the second process and a second conversion process is established, where the first conversion process and the second conversion process are both processes connected to the relay communications node in the second communications manner, a manner in which the first conversion process communicates with the first process is the first communications manner, and a manner in which the second conversion process communicates with the second process is the first communications manner; and in a case in which it is determined that the first communications manner is the same as the second communications manner, a connection between the first process and the relay communications node is established, and a connection between the second process and the relay communications node is established.

Still further, in this embodiment of the present invention, a connection between a process and a corresponding conversion process may be established in a manner of changing a target connection address of the process, and a connection between a process and the relay communications node may be established in the manner of changing a target connection address of the process; the following steps may be used in the specific establishing manner:

The establishing a connection between the first process and a first conversion process, and establishing a connection between the second process and a second conversion process is specifically: obtaining a target connection address of the first process and a target connection address of the second process; and changing the target connection address of the first process to an address of the first conversion process, and changing the target connection address of the second process to an address of the second conversion process. More specifically, when a process initializes a connection, a target connection address of the process may be changed in a hook manner.

The establishing a connection between the first process and the relay communications node, and establishing a connection between the second process and the relay communications node is specifically: obtaining the target connection address of the first process and the target connection address of the second process; and changing the target connection address of the first process to a first connection address, and changing the target connection address of the second process to a second connection address, where the first connection address is an address, which is in the relay communications node, for communicating with the first process, and the second connection address is an address, which is in the relay communications node, for communicating with the second process.

Further, for example, a communications protocol on which a manner of communication between processes is based generally includes memory sharing, a tcp protocol, a udp protocol, piping, a file, a semaphore, and the like. A second communications manner in which the relay communications node sends and receives data is similarly based on one of the foregoing protocols. A different communications protocol used indicates a different corresponding communications manner. The following specifically provides description by using an example in which a process A and a process B communicate with each other by using the tcp protocol, the process A and a process C communicate with each other by using the udp protocol, the process B and the process C communicate with each other by using the content sharing, and a second communications manner used by a relay communications node P is a tcp protocol-based communications manner, which is shown in FIG. 2a and FIG. 2b, and then that the relay communications node connected to each communications channel is added is specifically:

The process A is connected to a udp converter 1, to make the process A communicate with the udp converter 1 by using udp, the process C is connected to a udp converter 2, to make the process C communicate with the udp converter 2 by using udp, and the udp converter 1 and the udp converter 2 are both connected to the relay communications node P, where the two udp converters both communicate with the relay communications node P by using tcp, so as to add the relay communications node P to a communications channel between the process A and the process C. A target connection address of the process A may be changed to an address of the udp converter 1, to connect the process A to the udp converter 1, where to change the target connection address of the process A to the address of the udp converter 1 is to change the target connection address of the process A to a network port of the udp converter 1. Similarly, a target connection address of the process C may be changed to an address of the udp converter 2, to connect the process C to the udp converter 2, where to change a target connection address of a process C to the address of the udp converter 2 is to change the target connection address of the process C to a network port of the udp converter 2.

The process B is connected to a memory converter 1, to make the process B communicate with the memory converter 1 in the memory sharing manner, the process C is connected to a memory converter 2, to make the process C communicate with the memory converter 2 in the memory sharing manner, and the memory converter 1 and the memory converter 2 are both connected to the relay communications node P, where the two memory converters both communicate with the relay communications node P by using tcp, so as to add the relay communications node P to a communications channel between the process B and the process C. A target connection address of the process B may be changed to an address of the memory converter 1, to connect the process B to the memory converter 1, where to change the target connection address of the process B to the address of the memory converter 1 is to change a memory keyword of the process B to a memory keyword of the memory converter 1. Similarly, a target connection address of the process C may be changed to an address of the memory converter 2, to connect the process C to the memory converter 2, where to change the target connection address of the process C to the address of the memory converter 2 is to change a memory keyword of the process C to a memory keyword of the memory converter 2.

The process A and the process B communicate with each other by directly using the tcp protocol, and the communications manner is the same as that used by the relay communications node P. Therefore, the process A and the process B may be directly connected to a relevant communications address of the relay communications node P without a need to establish a connection between a process and a converter again.

Certainly, if the communications manner used by the relay communications node P is not a manner that is based on the tcp protocol, it needs to connect the process A to a tcp converter 1, to make the process A communicate with the tcp converter 1 by using tcp, and connect the process C to a tcp converter 2, to make the process C communicate with the tcp converter 2 by using tcp, and the tcp converter 1 and the tcp converter 2 are both connected to the relay communications node P, where the two tcp converters both communicate with the relay communications node P in the communications manner used by the relay communications node P, so as to add the relay communications node P to a communications channel between the process A and the process C. A target connection address of the process A may be changed to an address of the tcp converter 1, to connect the process A to the tcp converter 1, where to change the target connection address of the process A to the address of the tcp converter 1 is to change the target connection address of the process A to a network port of the tcp converter 1. Similarly, a target connection address of the process C may be changed to an address of the tcp converter 2, to connect the process C to the tcp converter 2, where to change a target connection address of the process C to the address of the tcp converter 2 is to change the target connection address of the process C to a network port of the tcp converter 2.

A tcp converter, a udp converter, a memory converter, and another converter for performing communications manner conversion all implement conversion processes by using programs.

After the relay communications node connected to each communications channel is added, a connection path between a process and the relay communications node is established. Accordingly, after the process is restarted, an original communications channel of the process is modified to a communications channel connected to the relay communications node. In this way, the data content that flows through the relay communications node, and the data flow direction may be monitored, to obtain communications data and a communications direction between the processes.

Preferably, after the establishing communications channels between the processes according to the obtained communications relationship in step S104, the monitoring method in this embodiment of the present invention further includes: drawing a communications topology view by using each of the processes as a node and using each of the communications channels as a node connection path; and displaying the communications topology view. In this way, a communications topology view that can visually reflect the communications relationship between the processes is provided for a tester.

Further, before the drawing a communications topology view by using each of the processes as a node and using each of the communications channels as a node connection path, the monitoring method further includes: controlling the multiple processes to be distributed in a multi-column form, where the processes that have the communications relationship are distributed in adjacent columns; or controlling the multiple processes to be distributed in a multi-row form, where the processes that have the communications relationship are distributed in adjacent rows. In this way, crossing of connection paths between the processes is prevented to the greatest extent, so that the communications topology view that is drawn can clearly and concisely reflect the communications relationship between processes. As shown in FIG. 3, which is a schematic diagram of a communications topology view generated by a monitoring method according to an embodiment of the present invention, this figure schematically shows that multiple processes are distributed in a multi-column form, and in FIG. 3, p0 indicates an external process, and p1, p2, …, and pn indicate multiple processes.

Preferably, after the monitoring data content that flows through the relay communications node, and a data flow direction, to obtain communications data and a communications direction between the processes in step S108, the monitoring method in this embodiment of the present invention further includes:

drawing a communications link, which points to the communications direction, between every two of the processes that have the communications relationship, and generating a communications sequence diagram, where each communications link has corresponding communications data; associating the communications topology view with the communications sequence diagram; receiving a first instruction from a client, where the first instruction from a client is used to select, from the communications topology view, at least two of the processes; and controlling the communications link between the selected processes to be displayed on the communications sequence diagram.

By drawing the communications sequence diagram, associating the communications sequence diagram with the communications topology view, and controlling the selected communications link to be displayed on the communications sequence diagram, an effect that the tester can voluntarily select, according to an intention of the tester, a process which the tester is concerned with, to observe a communications flow direction of the process is achieved.

After the communications sequence diagram is generated, the communications sequence diagram may further be displayed, which provides a sequence diagram that can visually reflect a communications flow direction between processes for the tester.

Further, after the controlling the communications link between the selected processes to be displayed on the communications sequence diagram, the monitoring method further includes: receiving a second instruction from a client, where the second instruction from a client is used to change, from the communications topology view, the selected processes; and controlling the communications link between the changed processes to be displayed on the communications sequence diagram. In this way, the communications link between the processes displayed on the communications sequence diagram is increased or decreased.

Still further, after the controlling the communications link between the selected processes to be displayed on the communications sequence diagram, the monitoring method further includes: receiving a third instruction from a client, where the third instruction from a client is used to select, from the communications sequence diagram, a target communications link; and displaying the communications data corresponding to the target communications link. The communications data between the processes is visually displayed for the tester.

Before the drawing a communications link, which points to the communications direction, between every two of the processes that have the communications relationship, and generating a communications sequence diagram, the monitoring method further includes: controlling the multiple processes to be distributed in a multi-column form, where only one of the processes is distributed in each column, and the processes in adjacent columns are different; or controlling the multiple processes to be distributed in a multi-row form, where only one of the processes is distributed in each row, and the processes in adjacent rows are different. As shown in FIG. 4, which is a schematic diagram of a communications sequence diagram generated by a monitoring method according to an embodiment of the present invention, this figure schematically shows that 7 processes, which are p1 to p7, are distributed in a multi-column form.

FIG. 5a is a flowchart of a process monitoring method according to an optional embodiment of the present invention. As shown in FIG. 5a, the monitoring method provided in the optional embodiment mainly includes the following step S5a02 to step S5a14:

S5a02: Obtain processes of a to-be-tested system and a communications relationship between the processes, where the number of the processes is multiple.

This step is the same as the foregoing step S102.

S5a04: Establish communications channels between the processes according to the obtained communications relationship.

This step is the same as the foregoing step S104.

S5a06: Add a relay communications node connected to each of the communications channels.

This step is the same as the foregoing step S106.

S5a08: Monitor data content that flows through the relay communications node, and a data flow direction, to obtain communications data and a communications direction between the processes.

This step is the same as the foregoing step S108.

S5a10: When it is monitored, by using the relay communications node, that a first process transmits a first request to a second process, send, by using the relay communications node, a second request transmitted by a third process to the first process, where the first request includes a first feature, the second request includes a second feature, the first process and the second process are any two processes that have a communications relationship in the multiple processes, the third process is a process, which is in the multiple processes, that has a communications relationship with the first process, the third process and the second process are different processes, and the first feature and the second feature are different features.

S5a12: Monitor a processing result of the first process for the second request.

S5a14: Determine a competition state of the first process according to the processing result.

In a procedure in which multiple processes complete a transaction collaboratively, a competition state window period exists. Therefore, for maintaining transactionality, the to-be-tested system needs to properly process a request in this period. By performing the foregoing step Sa510 to step Sa514, the tester inserts one data test request into one hierarchical invocation of a process group, to test whether a target process correctly processes the request. If the processing result indicates that the first process collapses, it may be determined that the competition state reflected in a response of the first process to a competition mechanism is weak. On the contrary, if the processing result indicates that the first process can correctly feed back a feedback for the second request, it may be determined that the competition state reflected in the response of the first process to the competition mechanism is strong. Testing, in a case in which a first process sends a request, a situation of a competition of the first process for a request received from a third party is implemented.

It is assumed that, the first process is a process maysvrd, the second process is a process world_login, and the third process is a process tconnd, and then the foregoing monitoring manner is that: when the process maysvrd sends a piece of data whose content includes a feature D1 to the process world_login, a piece of data whose content includes a feature D2 is sent from the process tconnd to the process maysvrd by using the relay communications node, to test whether the process maysvrd correctly processes the request. Specifically, the foregoing test rule may be defined in a JSON format as follows:

{

"when_from":maysvrd,//Condition of a source process

"when_to":world_login,//Condition of a target process

"feature":D1,//Feature of data content

"hack_from":tconnd,//Testing a to-be-sent source process

"hack_to":maysvrd,//Testing a to-be-sent target process

"payload":D2//Testing to-be-sent data

}

For a process monitoring apparatus provided in this embodiment of the present invention, a relay communications node connected to each communications channel between processes is added, so that data content that flows through the relay communications node and a flow direction can be monitored, to obtain communications data transmitted between the processes connected by the communications channel and a transmission direction of the data, and thereby monitoring of a communications logic between the multiple processes of the to-be-tested system is implemented, which solves a technical problem that the communications logic between the multiple processes cannot be monitored in the existing technology, thereby achieving a technical effect of performing a gray-box test on the communications logic between the processes of the to-be-tested system.

Specifically, the first monitoring unit 40 includes a monitoring subunit, where the monitoring subunit is configured to monitor data content of a first process and a second process that flows through the relay communications node, and a data flow direction, to obtain communications data and a communications direction between the first process and the second process, where the first process and the second process are any two processes that have a communications relationship in the multiple processes.

Further, the communications relationship obtained by the obtaining unit 10 includes a communications manner. In this embodiment of the present invention, the adding unit 30 mainly includes a first obtaining subunit, a first judging subunit, a first establishing subunit, and a second establishing subunit. The foregoing subunits mainly add, in the following manner, the relay communications node connected to each communications channel:

The first obtaining subunit is configured to obtain a first communications manner in which a first process and a second process send data to and receive data from each other, where the first process and the second process are any two processes that have a communications relationship in the multiple processes.

The first judging subunit is configured to determine whether the first communications manner is the same as a second communications manner in which the relay communications node sends and receives data.

The first establishing subunit is configured to: in a case in which the first judging subunit determines that the first communications manner is different from the second communications manner, establish a connection between the first process and a first conversion process, and establish a connection between the second process and a second conversion process, where the first conversion process and the second conversion process are both processes connected to the relay communications node in the second communications manner, a manner in which the first conversion process communicates with the first process is the first communications manner, and a manner in which the second conversion process communicates with the second process is the first communications manner.

The second establishing subunit is configured to: in a case in which the first judging subunit determines that the first communications manner is the same as the second communications manner, establish a connection between the first process and the relay communications node, and establish a connection between the second process and the relay communications node.

Still further, the first establishing subunit includes a first obtaining module and a first changing module, and the second establishing subunit includes a second obtaining module and a second changing module, where:

Further, for example, a communications protocol on which a manner of communication between processes is based generally includes memory sharing, a tcp protocol, a udp protocol, piping, a file, a semaphore, and the like. A second communications manner in which the relay communications node sends and receives data is similarly based on one of the foregoing protocols. A different communications protocol used indicates a different corresponding communications manner. By using an example in which a process A and a process B communicate with each other by using the tcp protocol, the process A and a process C communicate with each other by using the udp protocol, the process B and the process C communicate with each other by using the content sharing, and a second communications manner used by a relay communications node P is a tcp protocol-based communications manner, which is shown in FIG. 2a and FIG. 2b, the following specifically describes a specific principle for the adding unit 30 to add the relay communications node connected to each communications channel:

Preferably, the monitoring apparatus further includes a second drawing unit, an associating unit, a first receiving unit, and a second control unit, where after the first monitoring unit 40 monitors the data content that flows through the relay communications node, and the data flow direction, to obtain communications data and a communications direction between the processes, the second drawing unit is configured to draw a communications link, which points to the communications direction, between every two of the processes that have the communications relationship, and generate a communications sequence diagram, where each communications link has corresponding communications data; the associating unit is configured to associate the communications topology view with the communications sequence diagram; the first receiving unit is configured to receive a first instruction from a client, where the first instruction from a client is used to select, from the communications topology view, at least two of the processes; and the second control unit is configured to control the communications link between the selected processes to be displayed on the communications sequence diagram.

Further, the monitoring apparatus further includes a second receiving unit and a third control unit, where specifically, after the second control unit controls the communications link between the selected processes to be displayed on the communications sequence diagram, the second receiving unit is configured to receive a second instruction from a client, where the second instruction from a client is used to change, from the communications topology view, the selected processes; and the third control unit is configured to control the communications link between the changed processes to be displayed on the communications sequence diagram.

As shown in FIG. 8a, the monitoring apparatus provided in this optional embodiment mainly includes an obtaining unit 10, an establishing unit 20, an adding unit 30, a first monitoring unit 40, a first sending unit 501, a second monitoring unit 601, and a first judging unit 701.

The second monitoring unit 601 is configured to monitor a processing result of the first process for the second request.

The first judging unit 701 is configured to determine a competition state of the first process according to the processing result.

In a procedure in which the multiple processes complete a transaction collaboratively, a competition state window period exists. Therefore, for maintaining transactionality, the to-be-tested system needs to properly process a request in this period. By using the first sending unit 501, the second monitoring unit 601, and the first judging unit 701, the tester inserts one data test request into one hierarchical invocation of a process group, to test whether a target process correctly processes the request. If the processing result indicates that the first process collapses, it may be determined that the competition state reflected in a response of the first process to a competition mechanism is weak. On the contrary, if the processing result indicates that the first process can correctly feed back a feedback for the second request, it may be determined that the competition state reflected in the response of the first process to the competition mechanism is strong. Testing, in a case in which a first process sends a request, a situation of a competition of the first process for a request received from a third party is implemented.
