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.
Reporting Kubernetes Events to LTS
The cloud native logging add-on is not installed in a cluster.
During add-on installation, you can select Kubernetes events to create a default log collection policy, so that this add-on collects all events and reports them to LTS. For details about the add-on installation, see Collecting Data Plane Logs.
The cloud native logging add-on has been installed in a cluster.
- Log in to the CCE console and click the cluster name to access the cluster console. In the navigation pane, choose Logging.
- Click View Log Collection Policies in the upper right corner. All log policies reported to LTS in the current cluster are displayed.
- 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.
- On the logging management page, select the log stream configured in the log collection policy to view the events reported to LTS.
Reporting Kubernetes Events to AOM
For a Huawei Cloud cluster of version 1.19.16, 1.21.11, 1.23.9, or 1.25.4, after the cloud native logging add-on is installed, all Warning events and some Normal events are reported to AOM by default. The reported events can be used to configure alarms. For details about the add-on installation, see Collecting Data Plane Logs.
You can enable or disable this function when installing the add-on for an on-premises cluster.
Custom Event Reporting
If the reported events cannot meet requirements, you can modify the settings for the events.
- Run the following command on the cluster to modify the event collection settings:
kubectl edit logconfig -n kube-system default-event-aom
- Modify the event collection settings as required.
