[0067] The present invention also provides an application diagnosis method, referring to Figure 2 , Figure 2 It is a flowchart of the first embodiment of the diagnostic method of the present invention.

[0068] In this embodiment, the application diagnosis method includes:

[0069] Step S101, the diagnosis client component receives the notification information of the probe service information change sent by the registration discovery component;

[0070] In this embodiment, a diagnostic probe component is set for each K8s container. When each application service in the K8s container is started, the diagnostic probe component is loaded, and then the currently started application service obtains the corresponding service information. The service information may include the service name, IP address, and port information, etc. Then, the currently started application service performs a registration operation of the diagnostic probe component in the registration and discovery component based on the service information. Specifically, the registration and discovery component can bind the service information of the currently started application service with the corresponding diagnostic probe component.

[0071] Next, the diagnostic client component subscribes to the registered diagnostic probe component and obtains a diagnostic service list. Specifically, the diagnostic client component obtains the registered diagnostic probe component in the registered discovery component, and determines the diagnostic service list based on the application service corresponding to the registered diagnostic probe component. For example, the diagnostic client component obtains all service information bound to the registered diagnostic probe component in the registered discovery component, and generates a diagnostic service list based on each registered diagnostic probe component and all service information bound to the registered diagnostic probe component. The diagnostic service list may include service information of each application service and the corresponding diagnostic probe component. After the diagnostic client component subscribes to the diagnostic probe component, when the probe service information in the registered discovery component changes, the diagnostic client component is notified. For example, a notification message of the change in the probe service information may be sent to the diagnostic client component.

[0072] In this embodiment, the diagnosis client component receives the notification information of the probe service information change sent by the registration discovery component. Further, in a possible implementation, step S101 includes:

[0073] The diagnosis client component receives the notification information, wherein the registration discovery component sends notification information of the change of the probe service information of the first application service to the diagnosis client component when detecting that there is a first application service with service information change in the application services corresponding to the registered probe components.

[0074] In this embodiment, when there is a first application service whose service information has changed in the application services corresponding to the registered probe components, the registration and discovery component sends notification information of the change in the probe service information of the first application service to the diagnostic client component. For example, when the IP address changes after the application service is restarted, the registration and discovery component determines that the probe service information of the application service has changed; when the port information of the application service changes, the registration and discovery component determines that the probe service information of the application service has changed.

[0075] Step S102, obtaining first service information of a first application service in a K8s container corresponding to the notification information, and controlling the startup of a diagnostic probe component in the K8s container;

[0076] In this embodiment, after the diagnostic client component receives the notification information of the change in probe service information sent by the registration discovery component, it obtains the first service information of the first application service in the K8s container corresponding to the notification information. Specifically, the diagnostic client component can first obtain the diagnostic probe component corresponding to the notification information, determine the K8s container corresponding to the notification information based on the diagnostic probe component, and determine the application service in the K8s container whose probe service information has changed, and then obtain the first service information of the first application service whose probe service information has changed.

[0077] In this embodiment, when the first service information is obtained, the diagnostic client component controls the diagnostic probe component in the K8s container to start, so as to diagnose the first application service through the diagnostic probe component in the K8s container.

[0078] Step S103: diagnose application problems of the first application service through the diagnostic probe component based on the first service information.

[0079] In this embodiment, after the diagnostic probe component in the K8s container is started, the diagnostic client component diagnoses application problems on the first application service through the diagnostic probe component based on the first service information, so as to achieve timely diagnosis of the first application service and improve the fault diagnosis efficiency of the application service in the K8s container.

[0080] Furthermore, in a possible implementation, before step S101, the application diagnosis method further includes:

[0081] Step S104, obtaining the registered diagnostic probe components in the registration discovery component, and determining a diagnostic service list based on the application services corresponding to the registered diagnostic probe components;

[0082] Step S102 includes: if the first application service belongs to the diagnostic service list, obtaining the first service information.

[0083] Furthermore, in another possible implementation, before step S104, the application diagnosis method further includes:

[0084] Step S105: The second application service in the K8s container obtains corresponding second service information, and performs a registration operation of the diagnostic probe component in the registration discovery component based on the second service information.

[0085] Further, in another possible implementation, step S105 includes:

[0086] Step S1051, when the second application service is started, the diagnostic probe component is loaded;

[0087] Step S1052: the second application service obtains corresponding second service information, and performs a registration operation of the diagnostic probe component in the registration discovery component based on the second service information.

[0088] In this embodiment, a diagnostic probe component is set for each K8s container. When each second application service in the K8s container is started, the second application service loads the diagnostic probe component. Then, the currently started second application service obtains the corresponding second service information. The second service information may include the service name, IP address and port information of the second application service. Then, the currently started second application service performs a registration operation of the diagnostic probe component in the registration discovery component based on the second service information. Specifically, the registration discovery component can bind the second service information of the currently started second application service with the corresponding diagnostic probe component.

[0089] In this embodiment, the diagnostic client component subscribes to the registered diagnostic probe component and obtains the diagnostic service list. Specifically, the diagnostic client component obtains the registered diagnostic probe component in the registered discovery component, and determines the diagnostic service list based on the application service corresponding to the registered diagnostic probe component. For example, the diagnostic client component obtains all service information bound to the registered diagnostic probe component in the registered discovery component, and generates a diagnostic service list based on each registered diagnostic probe component and all service information bound to the registered diagnostic probe component. The diagnostic service list may include the service information of each application service and the corresponding diagnostic probe component. After the diagnostic client component subscribes to the diagnostic probe component, when the probe service information in the registered discovery component changes, the diagnostic client component is notified. For example, a notification message of the change in the probe service information may be sent to the diagnostic client component.

[0090] In this embodiment, when there is a first application service whose service information has changed in the application services corresponding to the registered probe components, the registration and discovery component sends notification information of the change in the probe service information of the first application service to the diagnostic client component. For example, when the IP address changes after the application service is restarted, the registration and discovery component determines that the probe service information of the application service has changed; when the port information of the application service changes, the registration and discovery component determines that the probe service information of the application service has changed.

[0091] In this embodiment, after the diagnostic client component receives the notification information of the change in probe service information sent by the registration discovery component, it determines whether the first application service belongs to the diagnostic service list. If the first application service belongs to the diagnostic service list, the first service information is obtained. Specifically, the diagnostic client component can first obtain the diagnostic probe component corresponding to the notification information, determine the K8s container corresponding to the notification information based on the diagnostic probe component, and determine the application service whose probe service information has changed in the K8s container, and then obtain the first service information of the first application service whose probe service information has changed.

[0092] The application diagnosis method proposed in this embodiment receives the notification information of the change of the probe service information sent by the registration discovery component through the diagnostic client component; then obtains the first service information of the first application service in the K8s container corresponding to the notification information, and controls the startup of the diagnostic probe component in the K8s container; then, based on the first service information, the application problem diagnosis is performed on the first application service through the diagnostic probe component, and the diagnostic probe component enables the diagnostic client component to automatically link to the K8s container to diagnose the application service. In the fault diagnosis process of the application service in the K8s container, there is no need for the intervention of the operation and maintenance personnel, which improves the fault diagnosis efficiency of the application service in the K8s container, thereby improving the problem troubleshooting efficiency and reducing the problem location time.

[0096] In this embodiment, after the diagnostic probe component in the K8s container is started, the diagnostic client component opens the diagnostic console and establishes a communication link with the first application service based on the first service information.

[0097] Then, after the communication link is established, the diagnostic client component diagnoses application problems on the first application service through the diagnostic probe component based on the communication link, that is, based on the communication link, the diagnostic client component diagnoses application problems on the first application service through the diagnostic probe component to achieve timely diagnosis of the first application service and improve the fault diagnosis efficiency of the application service in the K8s container.

[0098] The application diagnosis method proposed in this embodiment opens the diagnosis console and establishes a communication link with the first application service based on the first service information; then diagnoses the application problem of the first application service through the diagnosis probe component based on the communication link, and diagnoses the application problem of the application service through the diagnosis probe component by automatically opening the diagnosis console, so that the diagnosis client component can automatically link to the K8s container to diagnose the application service.

Specifically, the diagnostic client component can obtain the target IP address and target port information in the first service information in the diagnostic service list.

[0103] After obtaining the target IP address and target port information, the diagnostic client component establishes the communication link with the first application service based on the target IP address and target port information, wherein the communication link is a socket bidirectional link. It can be understood that the diagnostic client component establishes a socket bidirectional link channel with the first application service based on the target IP address and target port information through the existing socket bidirectional link algorithm.
