Alert template
Alert overview
- Template: ${alarm_target} ${operation_result}
- Example: logservice_cluster=my_ls_cluster:host=11.124.9.47 succeeded
Alert details
- Template: LogService cluster: ${logservice_cluster}, node: ${host}, alert: ${operation_name} ${operation_result}, operator: ${operator}, result: ${task_result}.
- Example: LogService cluster: my_ls_cluster, node: 11.124.9.47, alert: Restart node succeeded, operator: admin, result: Successful.
Alert recovery
- Auto-resolve (auto_resolved: 1), with a resolution cycle of 5 minutes.
Impact on the system
Node-level O&M may cause the node to be temporarily unavailable; the node may be in an abnormal state if the operation fails.
Possible causes
- The administrator performed an O&M operation on a node of the LogService cluster in the OCP console.
Solution
- Confirm whether it is an on-plan node maintenance
- Check the node process status and monitoring metrics after the operation is completed
- If the operation fails, troubleshoot and resolve the issue based on the task details.
