que-prometheus
Experimental
que-prometheus
is a "plugin" for que-rb/que
to support collecting job, worker and queue level metrics and exposing them to a prometheus collector on /metrics
and /queue/metrics
.
It's designed to support the same metrics that the gocardless/que
fork produces.
installation
$ bundle add que_prometheus
and add the stats view using a rails migration
require "que_prometheus/migrations"
class AddQuePrometheusView < ActiveRecord::Migration[7.0]
def up
::QuePrometheus::Migrations.migrate!(version: 1)
end
def down
::QuePrometheus::Migrations.migrate!(version: 0)
end
end
usage
bundle exec que ./config/environment.rb que_prometheus
Note: order is important, if que_prometheus
is before environment it will complain about a connection not being available.
This will expose two endpoints:
/metrics
which exposes metrics specific to the runningque
process/queue/metrics
which exposes queue summary metrics.
