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

OPENSTACK_AVAILABILITY_ZONE

To monitor Hypervisors in an Availability Zone, do not supply the 'Hypervisor Name' or 'Host Aggregate' variables.

Parameter Position in Variable Name Description
--zone Value OpenStack Availability Zone The name of the Availability Zone to monitor a set of hypervisors.

OPENSTACK_HOST_AGGREGATE

To monitor Hypervisors in an Aggregate, do not supply the 'Hypervisor Name' or 'Availability Zone' variables.

Parameter Position in Variable Name Description
--aggregate Value OpenStack Host Aggregate The name of the Host Aggregate to monitor a set of hypervisors.

OPENSTACK_HYPERVISOR_NAME

To monitor a single Hypervisor, do not supply the 'Availability Zone' or 'Host Aggregate' variables.

Parameter Position in Variable Name Description
--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.

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
