Copy Markdown View Source

Custom PromEx plugin exporting cache-effectiveness and overload metrics.

Tracks:

  • gamend_cache_reads_total — counter tagged by prefix (first element of the cache key tuple) and outcome (hit/miss), from Nebulex [:gamend, :cache, :command, :stop] events (:fetch only).
  • gamend_rate_limit_denies_total — counter tagged by scope (auth/general/ws/…), emitted by GamendWeb.RateLimit.
  • gamend_async_overload_total — async tasks run inline because Gamend.TaskSupervisor was at capacity.
