ovirt_exporter's Issues

Hello.

Unattached storage domains are reported as up

The metric ovirt_storage_up reports a value of 1 if the storage domain in unattached. Would be great to have something similar to #11 to differentiate between a storage domain up/online (=1), down (=0), maintenance (=2) or unattached (=3).

As reference for the StorageDomainStatus see here. Not sure if the up metric should track and expose all the 'transition' states (e.g. activating) as well.

grafana dashbord

Hello.

Whats about grafana dashbord . Do you dashbord example ?

install fails due to dependency change of prometheus/common/log

Question about ovirt_exporter functionality

Hi,

Just need some clarification on the functionality of ovirt_exporter. Does this export metrics from the ovirt metrics store or directly from the ovirt engine ? If it's from ovirt engine, does it contain metrics about all hosts created in ovirt engine ? Apologies for creating this as issue, didn't see any other option to ask this question.

This is the reference for Ovirt metrics store: https://www.ovirt.org/develop/release-management/features/metrics/metrics-store-installation.html

Thanks,
Venu.

Add metrics for VM disks

only optional because retrieving this kind of information is not cheap

401 Unauthorized

Hi. I'm getting 401 Unauthorized with ovirt 4.3.5.4-1.el7.

User prometheus has ReadOnlyAdmin role assigned.

ovirt_vm_snapshot_min/max_age_minutes has a misleading label

While I was building Grafana dashboards using the prometheus metrics generated by this exporter, I came across an issue where I thought that both ovirt_vm_snapshot_min_age_minutes and ovirt_vm_snapshot_max_age_minutes were measured in minutes as indicated by the naming scheme. After some poking around in the ovirt manager, I later realized that they were actually measured in seconds.

Typically prometheus metrics similar to these are measured in seconds so there's no problems with that, so only the metric labels need to be updated.

I created a new pull request here that fixes the labels.

It is possible to collect Host Maintenance metric?

For example ovirt_host_maintenance
Currently impossible to determine host down (ovirt_host_up 0) or just on maintenance, for example for certificate enrollment

possible checks:

# host down
(ovirt_host_up == 0) and (ovirt_host_maintenance == 0)

# host on maintenance
(ovirt_host_up == 1) and (ovirt_host_maintenance == 1)
