Release Notes / Version 11.2301
Table Of Contents
Spring Boot actuator endpoint
/metrics
provides several metrics on CoreMedia components (see
Operations Basics Manual
, section
Basics of Operation | Actuator Endpoints | Metrics Endpoint
). In addition to that, actuator endpoint
/prometheus
publishes this data for scraping by monitoring application
Prometheus
. However, cache metrics were incomplete for some CoreMedia components when using this endpoint. With this fix, the complete set of cache information can now be retrieved from it.
CoreMedia cache meter names in Spring Boot actuator endpoints
/metrics
or
/prometheus
have been changed:
cache.capacity -> coremedia.cache.capacity
cache.evaluation.duration -> coremedia.cache.evaluation.duration
cache.eviction.duration -> coremedia.cache.eviction.duration
cache.evictions -> coremedia.cache.evictions
cache.gets -> coremedia.cache.gets
cache.level -> coremedia.cache.level
cache.puts -> coremedia.cache.puts
cache.removals -> coremedia.cache.removals
cache.size -> coremedia.cache.size
cache.updates -> coremedia.cache.updates
Tag
cache
is not used on these meters any longer.
Meter names
cache.gets
,
cache.puts
,
cache.size
, and
cache.evictions
may still be present for other caches (depending on the component).
If you used cache metrics before, you may need to adjust your monitoring application's configuration according to the list above to comply with the new meter names for CoreMedia caches. See Operations Basics Manual , section Basics of Operation | Actuator Endpoints | Metrics Endpoint for details on metrics parameters.
