Description

Monitoring solutions (Ganglia, Advent Manage Engine, Hyperic) typically allow a JXM property to be polled and graphs produced. I’d like to be able to do this for cache effectiveness; e.g. 96% cache hits.

I hereby allow inclusion of the patch, yada. No CA or similar required?

check out the beta of the new ops console and associated rest api. We are also working on various integrations with tools.

Moving stuff out of the Canberra release right now. This functionality is being added as Ehcache DX in a separate of releases that will pick up this jira in a bit.

Greg is this something you want to include in Brisbane?

Is this related to EHC-497?

Moving all unresolved “Fix Revision 2.2.1” to fix revision “unknown” as we are releasing Magnum first which is 2.3. Currently not sure which fix version these will actually be in, but they are targeted for Fremantle release

I believe a much more interesting number to have when monitoring the performance of a cache is to have the % cache hit for a given region only (instead of a % of all hits of all regions).

This (trunk) patch does just that.

Also, I have completed the {{CacheStatistics}} (and associated {{CacheStatisticsMBean}}) to be feature-complete: there were missing a few off-heap-related numbers.
