Our Prometheus instance is public:

Usage instructions

  1. Install our package
  2. Add our rules_files entries to your prometheus.yml for each set of rules
    you wish to use
  3. Configure alertmanager accordingly

Our alerts are categorized into three severity groups:

  • interesting alerts are worth noting, as they may be useful in identifying
    trends over time, for forensic attention after an outage, or for addressing on
    a rainy day. Upstream, we send these to our IRC channel.
  • important alerts are likely to be actionable, but do not require immediate
  • urgent alerts require immediate attention.
