Whenever the
statsd_exporter's mapping is changed, the deployment will need to restart. This loses some metrics. Thestatsd_exporterexposes a lifecycle API: https://github.com/prometheus/statsd_exporter?tab=readme-ov-file#lifecycle-api in order to reload the mapping.This is great, because we can reload mappings without losing metrics and downtime. However, quoting the Kubernetes documentation:
In this MR we resolve it, by mounting all files from the Statsd ConfigMap in the
/etc/statsd-exporter. This results in the same end result in the container filesystem, as it only contains a single file (mappings.yml).^ Add meaningful description above
