Over time metrics will collect on your Prometheus Server and due to the nature and rate of the metrics being exposed we do not recommend sub-second scrapping_intervals. Renaming of metrics & deprecation of old names in 1.2. Workqueue metrics that follow prometheus best practices and naming conventions. Exporter for machine metrics. The appropriate base unit for timers does vary by metrics backend for good reason. Can only contain ASCII alphanumerics, underscores, and periods.

Metric names must start with a letter. Naming: value is the value to record; command is optional and is ‘overwrite’ by default. The most common option is to let Rails pick the name for database constraints and indexes or let PostgreSQL use the defaults (when applicable).
