Collecting Kubernetes Events

Billing

LTS does not charge you for creating log groups and offers a free quota for log collection every month. You pay only for log volume that exceeds the quota. For details, see Price Calculator.

Reporting Kubernetes Events to LTS

The Cloud Native Log Collection add-on has not been installed in a cluster.

You can select Kubernetes events when installing the Cloud Native Log Collection add-on. A default log collection policy will be created, and all events collected will be reported to LTS. For details about how to install the add-on, see Collecting Logs.

The Cloud Native Log Collection add-on has been installed in a cluster.

1. Log in to the CCE console and click the cluster name to access the cluster console. In the navigation pane on the left, choose Logging.

2. Click View Log Collection Policies in the upper right corner.

   All log collection policies reported to LTS are displayed.

3. Click Create Log Policy and configure parameters as required.

   Policy Template: If Kubernetes events is not selected during add-on installation or the log collection policy is deleted, you can use this option to create a default log collection policy.

   

4. On the Logging page, select the log stream configured in the log collection policy to view the events reported to LTS.

   

Reporting Kubernetes Events to AOM

After the Cloud Native Log Collection add-on is installed, all Warning events and some Normal events will be reported to AOM by default. The reported events can be used to configure alarms.

Custom Event Reporting

If the reported events cannot meet requirements, you can modify the settings for the events.

1. Run the following command on the cluster to edit the event collection settings:

   kubectl edit logconfig -n kube-system default-event-aom

2. Modify the event collection settings as required.

   apiVersion: logging.openvessel.io/v1
   kind: LogConfig
   metadata:
     annotations:
       helm.sh/resource-policy: keep
     name: default-event-aom
     namespace: kube-system
   spec:

           - NotTriggerScaleUp

       AOM:
         events:
         - name: DeleteNodeWithNoServer    # Event name. This parameter is mandatory.
           resourceType: Namespace    # Type of the resource that operations are performed on.
           severity: Major    # Event severity after an event is reported to AOM, which can be Critical, Major, Minor, or Info. The default value is Major.
