Make Info Metrics more easy to query

[rooftopcellist]

ISSUE TYPE

• Bug Report

SUMMARY

Currently awx_system_info and awx_instance_info metrics are returned as labels with values, which makes it difficult to query just the value of one key. As a result, you can't query individual key's for their values in prometheus, for example: awx_system_info{anisble_version}. This has already been fixed for licenses.

We should make the rest of these individual metrics so that they can be individually queried. i.e.: "I am a customer who likes to see my Ansible version and tower version in Dashboard for Tower in Grafana"

ENVIRONMENT

• AWX version: 4.0.0

I was able to change the info data to be individual line items, but am still unable to query just the value (given that the value is a str).

It looks like we could use UNTYPED data type (https://prometheus.io/docs/instrumenting/writing_exporters/#types)

But prometheus_client doesn't seem to support this, and futhermore, when I hardcode it into the metrics endpoint, I can't query it:

# HELP awx_version_info System Ansible version
# TYPE awx_version_info untyped
awx_version_info "9.7.10"
