Resque Exporter

Prometheus exporter for Resque metrics. Forked from upstream to maintain and package ourselves for our monitoring v2.

Usage

./resque-exporter

By default, the resque exporter collects metrics from redis://localhost:6379. You can change it using the --redis.url flag.

./resque-exporter --redis.url redis://redis.example.com:6379/1

If REDIS_URL environment variable is given, it takes precedence over the --redis.url flag.

REDIS_URL=unix:///var/run/redis.sock ./resque-exporter

If your Resque is using a non-default namespace (default is resque) to prefix its Redis keys, specify the namespace using the --redis.namespace flag.

./resque-exporter --redis.namespace app

Flags

$ ./resque-exporter --help
