View your current Cloudmon license details and extend the license when additional capacity or renewal is required. License keys are provided by the Cloudmon support team.
All Cloudmon services will stop and restart. This takes approximately 1 to 3 minutes. Monitoring and alerting will be briefly interrupted during this time -- schedule the restart during a maintenance window if continuous monitoring is required.
When the restart is complete, each service listed will show active (running) in the terminal output. If any service shows failed, contact Cloudmon Support before proceeding.
| Symptom | Likely Cause | Fix |
| License key is rejected when entered. | The key was generated against a different Installation ID, or was copied with extra whitespace. | Re-copy the Installation ID from the Extend License screen and confirm with the support team that the key was generated for that exact ID. Paste the license key carefully to avoid leading or trailing spaces. |
| SSH restart command returns a permission error. | The logged-in SSH user does not have root or sudo privileges. | Run the command as root or prefix with sudo: sudo service cloudmon-controller@* restart. If you do not have sudo access, contact your system administrator. |
| Controller web interface is unreachable after the service restart. | Services are still starting up, or one or more services failed to start. | Wait 3 minutes and refresh the browser. If still unreachable, run service cloudmon-controller@* status to identify any failed service and contact Cloudmon Support. |
