Usage Instructions
Step 1: Add this Host Template
Add the Cloud - OpenStack - Nova Hypervisor 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.
For more information, refer to Opsview Knowledge Center - Adding Host Templates to Hosts.
Step 2: Add and configure variables required for this Host Template

---|---|---|---|
--zone | Value | OpenStack Availability Zone | The name of the Availability Zone to monitor a set of hypervisors. |
OPENSTACK_HOST_AGGREGATE

---|---|---|---|
--hypervisor-name | Value | OpenStack Hypervisor Name | The name of the hypervisor to monitor; by default all hypervisors will be monitored. |
For more information, refer to Opsview Knowledge Center - Adding Variables to Hosts.
For mode-specific help, run the plugin with the -h -m <mode> flags. This will list the required and optional Variable Arguments for that mode. The appropriate mode for each Service Check is listed here:
Service Check Name | Mode |
---|---|
OpenStack - Nova Hypervisor - Active State | OpenStack.Nova.Hypervisor.State |
OpenStack - Nova Hypervisor - Available Disk Space | OpenStack.Nova.Hypervisor.Disk |
OpenStack - Nova Hypervisor - Available Memory | OpenStack.Nova.Hypervisor.Memory |
OpenStack - Nova Hypervisor - Services | OpenStack.Nova.Hypervisor.Services |
OpenStack - Nova Hypervisor - System Load | OpenStack.Nova.Hypervisor.Load |
OpenStack - Nova Hypervisor - Virtual CPUs | OpenStack.Nova.Hypervisor.VCPUs |
OpenStack - Nova Hypervisor - Virtual Machines | OpenStack.Nova.Hypervisor.VMs |
SSL Certificates
Additionally, if ssl verification is required, you can use the following variable to pass in your SSL certificates for use when connecting to the service provider to gather metrics:
OPENSTACK_CERTIFICATES
The Value is not used and therefore can be set to anything. Override the arguments with your certificates.
Parameter | Position in Variable | Name | Description |

Step 3: Apply changes and the system will now be monitored
Troubleshooting Permissions
The Opsview 'read' user requires 'GET' access to the following Nova endpoints with minimum scope of 'project':
- /os-hypervisors/detail
- /os-availability-zone/detail
- /os-aggregates
- /os-services
