Tim Armstrong resolved IMPALA-8799.
-----------------------------------
Resolution: Fixed
Fix Version/s: Impala 3.3.0
> Prometheus metrics should be prefixed with "impala_"
> ----------------------------------------------------
>
> Key: IMPALA-8799
> URL: https://issues.apache.org/jira/browse/IMPALA-8799
> Project: IMPALA
> Issue Type: Improvement
> Components: Backend
> Reporter: Tim Armstrong
> Assignee: Tim Armstrong
> Priority: Major
> Labels: observability
> Fix For: Impala 3.3.0
>
>
> This is recommended by the Prometheus docs -
> https://prometheus.io/docs/practices/naming/
> {quote}
> A metric name...
> ...must comply with the data model for valid characters.
> ...should have a (single-word) application prefix relevant to the domain
> the metric belongs to. The prefix is sometimes referred to as namespace by
> client libraries. For metrics specific to an application, the prefix is
> usually the application name itself. Sometimes, however, metrics are more
> generic, like standardized metrics exported by client libraries. Examples:
> prometheus_notifications_total (specific to the Prometheus server)
> process_cpu_seconds_total (exported by many client libraries)
> http_request_duration_seconds (for all HTTP requests)
> {quote}
> It is also awkward in tools like grafana to find impala metrics with the
> current naming scheme.
