heroku-buildpack-sidekiq-metrics

This Heroku buildpack provides sidekiq metrics.

See also https://github.com/mperham/sidekiq/wiki/Monitoring

How does it affect my slug?

This buildpack does two things:

1. Copies .profile.d/ruby-sidekiq-metrics.sh script into your slug
   • See also Dynos and the Dyno Manager > Startup > The .profile file
2. Copies sidekiq-metrics script into your slug

The .profile.d/ruby-sidekiq-metrics.sh script starts the sidekiq-metrics script on web.1 Dyno boot.

The sidekiq-metrics script is called every 30 seconds and outputs the following log to stdout:

source=sidekiq queue=default size=3 latency=0 threshold=below
source=sidekiq queue=low size=42 latency=1 threshold=above

Requirements

• bundler
• heroku/ruby buildpack
• sidekiq

Customize

• SIDEKIQ_METRICS_DYNO (Default: web.1)
  • The Dyno name which the sidekiq-metrics script boot as daemon
• SIDEKIQ_METRICS_INTERVAL (Default: 30)
  • Polling interval (seconds) which the sidekiq-metrics script is called
• SIDEKIQ_METRICS_THRESHOLD (Default: 30)
  • Latency interval (seconds) that causes script to print whether threshold is exceeded or not
  • Can be a global threshold for all queues or separate value per queue (e.g. default:30,low:300 or 30,low:300)
