Regarding: this query for Octavia loadbalancers
I raised an issue #70

The Niedbalski exporter returns only loadbalancers that have lb.provisioning_status = "ACTIVE"
Without a condition in the query, it will return all loadbalancers, including the ones with lb.provisioning_status = "DELETED"

So behaviour is not identical and for some users, switching exporters will result in receiving more metrics than before.

Will this be mentioned/addressed or should it be changed to mimic the Niedbalski exporter?

For Glance, the Niedbalski exporter does the following:

allPagesImage, err := images.List(exporter.Client, images.ListOpts{}).AllPages()

The equivlant Openstack CLI command as admin would be:

openstack image list -f value -c id | wc -l

But if we run the query used here:

# Simplified
SELECT * FROM images WHERE deleted=0

We get also images where os_hidden=1, which Openstack API does not expose. So this exporter will not produce the same metrics, it will produce more for some users. In particular, the metric

openstack_glance_images

can have a potentially much higher number than before, causing sudden jumps in dashboards when exporters are switched.

So either we ensure that the exporter only exports os_hidden=0 or we address/mention this in the audit report.

For Neutron, the metrics:

openstack_neutron_subnets_free
openstack_neutron_subnets_total
openstack_neutron_subnets_used

Are missing, there is an implementation in this branch; it involves a bit of math; was adapted from what was found in the Niedbalski exporter
