Deduplication and renaming of metric cache_size
We were double registering the existing metric cache_size
. In Grafana v12 we’re deprecating the metric, with plans to remove it in Grafana v13, and splitting it into 2 different metrics:
resource_cache_size
query_cache_size
While available metrics are not officially documented, you may still use them to get information on the state of your instance.
Migration/mitigation
You’ll continue getting data by using the cache_size
metric, but we recommend you update your dashboards to use the resource_cache_size
and query_cache_size
metrics instead.
