add `exporter_version` label #12

Closed kworr closed 2 years ago

Misses two nice metrics:

ntp_version 1.1.1
ntp_up{server="127.0.0.1"} 1

Would be nice to have a track on whats installed where (I have a few hundreds of 'em) and also detect whether exporter is actually running. Right now on hosts with chrony it just returns nothing.

Ah, might be done easier:

ntp_up{exporter_version="1.1.1", server="127.0.0.1"} 1

You can see whether the exporter is running by checking the up metric generated by Prometheus. The exact set of labels depends on your scrape config.

See here for more information: https://prometheus.io/docs/concepts/jobs_instances/ - Excerpt:

The up time series is useful for instance availability monitoring.

Um, that's nice. Thank you.

I'll leave the issue open for the other part of the request, about adding an exporter_version label to the metrics.
