Nagios Support Forum

Hi All,

I have installed nagios core 4.0.1 on CentOS6.4 using official document. In the same host I have installed open source cloud computing software openstack using all in one instaltion by RDO.

I have launched linux and windows instances through openstack. I need nagios to monitor cpu utilization, memory usage of all the instances in that openstack cloud.

How can It is possible through Nagios core.

I can login to ServerIP/nagios through web interface. Does it mean my installation is correct??

How to install clients in virtual instances, So that I can monitor from nagios dashboard. I am totally stuck in this part.

Kindly anyone help me who has succesfully monitored openstack virtual machines.

Thanks & Regards,
Anand TS

You should be able to use any of the standard agents on the guest vms. Openstack itself needs a special plugin or two to be monitored:

Are you running zen or kvm?

I am using kvm as hypervisor.

How can I install plugins if vm guests are windows. If I install NSclient++ in windows machine and nagios core in ma host machine, Will they communicate with eachother.

You can do that, though they will need to communicate through tcp as they normally would. You may be better off running nagios on a guest instead of the kvm host.
