#Architecture

#Inspection

The inspection module is jointly provided by the platform component Courier and the monitoring component, involving the following business processes:

• Create inspection task: The platform submits an inspection-type CR to the global cluster.
• Execute inspection task: The Courier component monitors the generation of inspection-type CRs and queries the monitoring components of each cluster for various metric data related to the inspection.
• Write inspection results: After the Courier component completes the evaluation of each inspection item, it will write the inspection results back into the corresponding inspection CR.
• View inspection results: Users can check the status and results of inspection tasks through the platform, where data will be obtained from the corresponding inspection CR.

#Component Health Status

Component health status is jointly provided by the platform component Courier and the monitoring component, involving the following business processes:

• Predefined component monitoring list: The platform has predefined two types of CRDs in the global cluster to define the list of components to be monitored and the monitoring methods:
  • ModuleHealth: Defines the components that need to be monitored and the monitoring methods.
  • ModuleHealthRecord: Defines the monitoring results of the corresponding components in each cluster.
• Regularly monitor component status: Courier will watch ModuleHealth, check the specified functions, and then write the inspection results to the CR resources of ModuleHealth and ModuleHealthRecord.
• Component status determination: Courier will request data from Kubernetes and the monitoring components to determine the actual status of the components and any existing issues.
  • Kubernetes: Checks whether the component is installed and whether the number of component replicas is normal.
  • Prometheus / VictoriaMetrics: Based on the metrics provided by each component, queries and determines whether the component can provide services normally.
• View component health status: Users can check the health status of each component through the platform, where data will be obtained from the corresponding CR resources of ModuleHealth and ModuleHealthRecord.
