Monitoring compute services
The final set of services to monitor are those on the compute node. Here, you can make sure a couple of services are running and add the ping from the section you just finished. Start with the generic service status check for these services:
neutron-openvswitch-agent openvswitch neutron-ovs-cleanup openstack-ceilometer-compute openstack-nova-compute
Then add a service configuration to Nagios that will run the ping command to check your tunnel connectivity.
define service { check_command check_nrpe!check_ovs_tunnel host_name compute service_description OVS tunnel connectivity use generic-service }
As you can see, this is just an NRPE check command that will execute a ping from the compute node to the network node.
