I think you need to look at the source code for the Openstack exporter :)

Hey Saurabh,

can you provide the exporter you use and its version? There are multiple openstack exporters and without a version it's hard to tell the exact solution. However, as I recently looked into the codebase the metric describes that the neutron service can't be reached. As I recall it is a catch-all when exporting neutron metrics which gets set to 0 if neutron service is unavailable.

Best,

Michael

Hey,

Thanks for the update.

Openstack Exporter version which we are using is 1.0.0. The point is the status of different neutron services for eg neutron-openvswitch-agent,neutron-l3-agent etc are in UP State then why the metric value of openstack_neutron_up is 0 .

Even I checked with Openstack team and they confirmed that the  neutron service is available.

Hey,

Peeking in the source code I assume there is one metric which causes an error:

https://github.com/openstack-exporter/openstack-exporter/blob/v1.0.0/exporters/exporter.go#L97

So, if one metric fails being collected within the neutron export, independent of the reason, it is set to `0`.

Assuming that you run the exporter as non-admin there could be errors in metrics related to missing access rights. This should also be within the logs.

To mitigate that you can disable the metrics causing errors.

Best,

Michael
