Release Notes / Version 11.2310
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.
