Dovecot exporter
This repository provides a dovecot_exporter utility that can be used
to scrape statistics from Dovecot and export them as Prometheus metrics.
It extracts the metrics that are exposed by
Dovecot's stats module by
connecting to UNIX socket /var/run/dovecot/stats and serves them as
Prometheus metrics over TCP port 9166.
A list of command line flags supported by this utility can be obtained
by looking at this exporter's main() function. Do note that all
command line flags require two leading dashes (e.g.,
--dovecot.scopes).
The metrics provided by this exporter look like this:
