[Proposal] A Squid Client Info gauge

[aSapien]

Hi,

I have a use-case very similar to the one described here 0

In my scenario, I need to use a client_ip from the squid logs in concert with a prometheus metrics query within the same Grafana panel, which is currently impossible as described in the discussion 0 and with some more evidence of the issue here 1.

In order to, within the context of squid-exporter, eliminate the need for a mixed-datasource/dashboard-datasource query 2 entirely, I want to propose an exporter of a squid_client_info gauge quite similar in its properties to kube_pod_info 3 exported by kube-state-metrics 4.

This gauge must contain the HTTP source IP, but it may also be useful to add some other other useful HTTP information such as user-agent and/or response-code.

Your thoughts?

squid exporter is currently relying on cache manager to export metrics. while I see the utility of this new metric(s), iiuc, it requires processing of the squid logs, which is a big project by itself. If you can invest in building this new feature and proposing the PR I'll gladly review the change.
