DETAILED DESCRIPTION

[0046] The exemplary embodiments will be described in detail herein with reference to the attached drawings. In the following description, like reference numerals refer to like elements throughout the description. The following exemplary embodiments are not representative of all embodiments consistent with the present application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the present application as detailed in the appended claims.

[0047] It should be noted that the PaaS application exception detection method, device and equipment provided in the present application can be used in the field of cloud computing, and can also be used in any field other than cloud computing. The application field of the PaaS application exception detection method, device and equipment in the present application is not limited.

[0048] First, the PaaS application exception detection method, device and equipment provided in the present application will be described in combination with Figure 1 The application scenario suitable for the present application is introduced.

[0049] Figure 1 A schematic diagram of an application scenario provided by an embodiment of the present application is shown in Figure 1 As shown, the application scenario includes a PaaS application server 11 and a PaaS control device 12. The PaaS application server 11 and the PaaS control device 12 can communicate through a network. The PaaS application server 11 is provided with a plurality of application programs, and the plurality of application programs are deployed in an application container.

[0050] In the related art, as shown in Figure 2 The PaaS control device initiates the execution of a health check link or a health script at regular intervals, judges the health of the application program according to the returned result, and initiates the restart of the application container if the health is abnormal. However, in the above health check scheme, the health detection of the application side is closely coupled with the overall operation of the application container, and it is unable to distinguish whether the health detection abnormality is caused by the problem of the application program itself or the problem of the environment of the application container.

[0051] The PaaS application exception detection method provided in the present application aims to solve the above technical problems in the prior art.

[0052] The technical solutions of the present application and how the technical solutions of the present application solve the above technical problems will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes can not be described again in some embodiments. The embodiments of the present application will be described below with reference to the drawings.

[0053] Figure 3 The flow of the PaaS application exception detection method provided by an embodiment of the present application is shown in Figure 1The method is applied to a PaaS application server, and a PaaS application is deployed in an application container, as shown in Figure 3 The method comprises the following steps.

[0054] S301. Receiving a health detection instruction sent by a PaaS control device.

[0055] Specifically, the health detection instruction sent by the PaaS control device is used to instruct the PaaS application server to perform health check on the application container and the application deployed in the application container.

[0056] Optionally, the PaaS control device can send the health detection instruction at a regular time to trigger the PaaS application server to perform the health check. Optionally, before sending the health detection instruction, it can be detected whether a time interval from a last health check is greater than or equal to a preset threshold; if the time interval is greater than or equal to the preset threshold, the health detection instruction is sent, that is, the health check is performed.

[0057] S302. Performing system-level health check on the application container according to the health detection instruction by using an agent.

[0058] Specifically, the agent performs system-level health check on the application container according to the health detection instruction, for example, checks CPU, memory, process, storage device, input and output (IO), etc., such as CPU occupancy, memory usage (such as checking whether there is memory leakage or deficiency), number of running processes, available space of the storage device, read and write speed, etc., whether the read and write operations are normal, such as whether the read and write speed is normal, etc.

[0059] Based on the information obtained by checking the above aspects, it is determined whether the state of the application container is healthy, that is, whether the health check result is normal.

[0060] S303. If the system-level health check result of the application container is normal, performing health check on the application by using the agent.

[0061] If the health check result of the application is normal, performing health check on the application by using the agent to ensure that the application runs normally. The health check of the application usually includes at least one of the following aspects:

[0062] 1. Availability check: ensuring that the application is accessible. For example, it is achieved by verifying whether a preset response information is returned by a simple HTTP request.

[0063] 2. Response time: monitoring the response time of the application to ensure that it provides a response within a reasonable time range. A too long response time may indicate a performance problem.

[0064] 3. Resource usage: Check the system resources used by the application, including CPU, memory, disk I / O, and network bandwidth, to ensure they are within normal ranges.

[0065] 4. Dependency check: Verify that external services or components on which the application depends (such as databases, cache services, third-party Application Programming Interfaces (APIs), etc.) are functioning properly.

[0066] 5. Log monitoring: Analyze application logs to detect errors, exceptions, or warning messages, which can help identify potential issues.

[0067] 6. Database connectivity: Ensure that the application can successfully connect to the database and perform basic query operations.

[0068] 7. Security check: Verify that the security configuration of the application is correct, including checking the validity of certificates, and that authentication and authorization mechanisms are working properly.

[0069] 8. Load testing: Conduct periodic load testing to determine the performance and stability of the application under high load conditions.

[0070] 9. Version and configuration check: Ensure that the version and configuration of the application are up-to-date and meet expectations.

[0071] By conducting regular health checks on the above aspects, potential issues can be identified and addressed, ensuring the reliability and performance of the application.

[0072] S304, if the health check result of the application is abnormal, return first exception information to the PaaS control device, and the first exception information is used for the PaaS control device to process the abnormal application.

[0073] If the health check result of the application in S303 is abnormal, that is, the state of the application is abnormal, first exception information is returned to the PaaS control device, and the first exception information is used for the PaaS control device to process the abnormal application, such as indicating to restart the application or issuing an alarm.

[0074] The abnormality detection method of the PaaS application provided by the embodiment comprises the following steps: receiving a health detection instruction sent by a PaaS control device; performing system-level health checking on an application container according to the health detection instruction by using an agent; if the system-level health checking result of the application container is normal, performing health checking on the application program by using the agent; further, if the health checking result of the application program is abnormal, returning first abnormality information to the PaaS control device, and the first abnormality information is used for the PaaS control device to process the abnormal application program. In the above scheme, the health checking of the application program and the application container is decoupled. First, the system-level health checking is performed on the application container. If the checking result is normal, the health checking is further performed on the application program. If the health checking result of the application program is abnormal, the abnormality processing is performed on the application program, so as to facilitate the positioning and processing of the problem when the health detection is abnormal.

[0075] In some embodiments, the step S303 of performing health checking on the application program by using the agent can be implemented in the following manner:

[0076] The agent is used to call a detection program script or a detection link to perform health checking on the application program.

[0077] Specifically, the detection program script or the detection link used for health detection of the application program can be set in advance, and the agent can be used to call the detection program script or the detection link to perform health checking on the application program.

[0078] In the above embodiment, the agent is used to call the detection program script or the detection link to perform health checking on the application program, so that the health checking of the application program can be quickly implemented, and the efficiency is high.

[0079] In some embodiments, the step S303 of performing health checking on the application program by using the agent can be implemented in the following manner:

[0080] According to the priority of the application program, the application program to be checked is determined.

[0081] The agent is used to perform health checking on the application program to be checked.

[0082] Specifically, the priority of the application program can be determined, and the application program to be checked at present can be determined based on the priority. For example, for multiple application programs, the multiple application programs can be sequentially subjected to health checking according to the priority, so that the multiple application programs are not simultaneously subjected to checking, and the resources are not occupied too much, thereby avoiding affecting the normal use of the business.

[0083] In some embodiments, after the step S304, the following step is further included:

[0084] receiving a first restart instruction sent by the PaaS control device; the first restart instruction is used to instruct to restart the abnormal application;

[0085] restarting the application according to the first restart instruction.

[0086] Specifically, the PaaS control device receives first exception information indicating that the health check result of the application is abnormal, sends a first restart instruction to the PaaS application server, and instructs to restart the abnormal application; the PaaS application server restarts the application according to the first restart instruction. For example, the PaaS application server restarts the application according to the first restart instruction by using an agent.

[0087] In the above embodiment, the PaaS control device sends a first restart instruction to the PaaS application server to instruct to restart the abnormal application, which realizes problem troubleshooting of the abnormal application and does not need to restart the entire application container, thereby reducing the impact on the entire system.

[0088] In some embodiments, the step S302 of "restarting the application container according to the health detection instruction by using an agent" can be implemented in the following manner:

[0089] collecting state information of the application container at a system level by using the agent, the state information including at least one of the following: CPU state information, memory state information, process state information, storage device state information, and input / output (IO) state information;

[0090] determining a health check result of the application container at a system level according to the state information of the application container at a system level;

[0091] After the step S302, the method further includes:

[0092] if the health check result of the application container at a system level is abnormal, returning second exception information to the PaaS control device;

[0093] receiving a second restart instruction sent by the PaaS control device; the second restart instruction is used to instruct to restart the application container;

[0094] restarting the application container according to the second restart instruction.

[0095] Specifically, in the system-level health check of the application container, the Agent is used to collect the system-level state information of the application container, and the system-level health check result of the application container is determined according to the collected system-level state information of the application container.

[0096] For example, for the CPU state information, if the CPU occupancy rate is greater than or equal to a first preset threshold, it is determined that the system-level health check result of the application container is abnormal.

[0097] For the memory state information, if the memory usage rate is greater than or equal to a second preset threshold, it is determined that the system health check result of the application container is abnormal.

[0098] For the process state information, if the number of simultaneously running processes is greater than or equal to a third preset threshold, it is determined that the system health check result of the application container is abnormal.

[0099] For the storage device state information, if the available space of the storage device is less than or equal to a fourth preset threshold, it is determined that the system health check result of the application container is abnormal; or, if the read-write speed of the storage device is less than or equal to a fifth preset threshold, it is determined that the system health check result of the application container is abnormal.

[0100] For the IO state information, if the read-write speed of the read-write operation is less than or equal to a sixth preset threshold, it is determined that the system health check result of the application container is abnormal.

[0101] Optionally, if the system-level health check result of the application container is abnormal, the PaaS control device returns second abnormal information; the PaaS control device sends a second restart instruction to the PaaS application server according to the second abnormal information, the PaaS application server receives the second restart instruction sent by the PaaS control device; the second restart instruction is used to instruct to restart the application container; the PaaS application server restarts the application container according to the second restart instruction, realizing abnormal processing of the system level.

[0102] In the above embodiment, the Agent is used to collect the system-level state information of the application container, and the system-level health check result of the application container is determined according to the system-level state information of the application container; the system-level health check of the application container is realized, and the state information of the application container is more easily collected, thereby improving the reliability and user experience of the system.

[0103] For example, as shown in Figure 5 the method comprises the following steps:

[0104] S51, the PaaS control device triggers a health detection instruction at a time;

[0105] S52, determining whether to perform system-level health check of the application container;

[0106] If it is determined to perform system-level health check of the application container, performing S53, the Agent collects health status information of the application container system level, and performs health check;

[0107] If it is determined not to perform system-level health check of the application container, performing S54, the Agent calls the detection program script or detection link of the application program, and performs health check of the application program;

[0108] If it is not a health detection instruction, performing S55, determining whether it is a container restart instruction;

[0109] If it is a container restart instruction, performing S56, restarting the application program;

[0110] If it is not a container restart instruction, performing S57, the Agent calls the program script to restart the abnormal application program.

[0111] Figure 6 The flow of the abnormal detection method of the PaaS application provided by the embodiment Figure 2 The method is applied to a PaaS control device, and a PaaS application is deployed in an application container, as shown in Figure 6 The method comprises the following steps.

[0113] S602, receiving first abnormal information sent by the PaaS application server; the first abnormal information is sent in the case that the health check result of the application program is abnormal;

[0114] S603, processing the abnormal application program according to the first abnormal information.

[0115] In some embodiments, the processing of the abnormal application program according to the first abnormal information comprises:

[0116] sending a first restart instruction to the PaaS application server; the first restart instruction is used to instruct to restart the abnormal application program.

[0117] In some embodiments, the method further comprises:

[0118] receive second exception information sent by the PaaS application server; the second exception information is sent in a case where it is determined that the system-level health check result of the application container is abnormal, and the system-level health check result of the application container is determined based on state information of a system level of the application container;
