Summary

Fixes two issues with non-SLA alerting for all AppCat services:

  1. MariaDB container name - MemoryCritical alert was querying wrong container (mariadb instead of mariadb-galera)
  2. Regex capture groups - label_replace() patterns missing parentheses, breaking $1 substitution in alert labels
  3. Alert flapping - PersistentVolumeFillingUp firing repeatedly due to the duration being 1 minute. This is increased to 15 minutes
