'Collect VM uptime from openstack cloud
I would like to collect uptime info from a VM provisioned in Redhat Openstack. Is there a native service in OpenStack to continually provide the system logs (with uptime info)? I checked Nova VM diagnostics capability - https://wiki.openstack.org/wiki/Nova_VM_Diagnostics#Overview but i am still trying to figure out if i should have it on an agent on the VM in openstack to provide me the logs or is there any better and elegant way to do it?
Solution 1:[1]
You can use the Gnocchi service for information about server uptime.
Solution 2:[2]
you can use one of these solutions
- setup ceilometer with seprated rabbit-mq cluster
- use libvirt exporter (if you are using kvm/qemu) and prometheus.
- setup custom script and send it to instance via cloud-init (not very good idea if you are not the owner of instance)
