Add "cluster" label for hosts, vms and datastores
It would be great to add "cluster" label to indicate to which HA cluster the host/vm belongs to.
Same, for datastores that belong to a Datastore cluster.
We manage multiple clusters with the same vCenter, and would like to filter metrics per "PROD" and "STAGING" clusters, for example.
@rverchere looking at pyvmomi and vsphere api, I believe there is no simple way to add this label.
But, we should be able to create a new set of metrics with this information, for example:
vmware_vm_dc_cluster{vm_name="vm1",dc_name="dc1",cluster_name="cluster1"} 1
vmware_host_dc_cluster{host_name="host1",dc_name="dc1",cluster_name="cluster2"} 1
vmware_datastore_dc_cluster{ds_name="ds1",dc_name="dc1",cluster_name="cluster3"} 1
Taking some inspiration on how to retrieve this data from here: https://github.com/vmware/pyvmomi-community-samples/blob/master/samples/getvmsbycluster.py
Once we have these metrics in place, we can use the PromQL grouping capability to build queries like so:
(sum(vmware_host_cpu_usage) / sum(vmware_host_cpu_max) * 100) * ON (host_name) group_left(cluster_name) vmware_host_cluster{cluster_name="PROD"}
The above would be very valuebale to us, as it will allow us to aggregate metrics based on the relevant clusters, espeically for alerting since Prod and Staging hosts/vms/datastores are not to be treated the same.
/edit: I think it would also make sense to include the datacenter name as well (examples updated above), also needless to say but these should only be collected from vcenter target(s).
@rverchere sorry for nagging 😄 just wondering if you had a chance to look into this?
@dannyk81 pong : https://github.com/rverchere/vmware_exporter/blob/master/README.md#unmaintained
Sorry but I started new job with new monitoring tools, so I cannot continue maintain this exporter (yet).
@rverchere I know you're no longer working on this, but perhaps you will consider to include https://github.com/rverchere/vmware_exporter/pull/36
It provides a meta metric with labels that describe the datacenter, cluster and host per VM.
It can be easily used in PromQL to filter other metrics based on these parameters.
