Troubleshooting
If you find that an infrastructure is in a DEGRADED or ERROR state, you may be able to rectify the situation by restarting certain services on the Agent VM.
| Alert Name | Affected VM OS Service Name |
|---|---|
| INFLUXDB | influxdb |
| KAPACITOR | kapacitor |
| MONITORING | monitoring |
| ONBOARDING | onboarding |
| RCLONE | rclone |
| TELEGRAF | telegraf |
Perform the following procedure to clear alerts for an infrastructure with ERROR or DEGRADED status:
Validate the connection between the Agent VM and vCenter.
Examine the infrastructure health, and identify the component associated with each critical or warning alerts.
SSH into the Agent VM.
Restart each affected service. For example:
user@agentvm$ systemctl restart influxdb.serviceCheck the infrastructure status and health again.
Ensure that all components display the OK status.
