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.

OPENSTACK_PROJECT

Parameter	Position in Variable	Name	Description
--project	Value	OpenStack Project	The OpenStack project you wish to monitor.

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.

Parameter	Position in Variable	Name	Description
--ca-path	Arg1	CA Certificate Path	Path to the CA Certificate. Optional, only required if server verification is needed.
--client-cert	Arg2	Client Certificate Path	Path to the Client Certificate. Optional, only required if client verification is needed.
