Usage Instructions

Step 1: Add this Host Template

Add the Cloud - OpenStack - Nova Server Host Template to your Opsview Cloud host. If the resource you're monitoring has no hostname or public IP, then open the Advanced settings pane and change Host Check Command to Always assumed to be UP.

Troubleshooting Permissions

The Opsview 'read' user requires 'GET' access to the following Nova endpoints with minimum scope of 'project':

  • /servers
  • /servers/{server_id}
  • /servers{server_id}/diagnostics
