rsyslog_exporter

A prometheus exporter for rsyslog. It accepts rsyslog impstats metrics in JSON format over stdin via the rsyslog omprog plugin and transforms and exposes them for consumption by Prometheus.

Rsyslog Configuration

Configure rsyslog to push JSON formatted stats via omprog:

module(
  load="impstats"
  interval="10"
  format="json"
  resetCounters="off"
  ruleset="process_stats"
)

ruleset(name="process_stats") {
  action(
    type="omprog"
    name="to_exporter"
    binary="/usr/local/bin/rsyslog_exporter"
  )
}
