--------------------------------
Summary: Missing few metrics in new metrics system
Key: IGNITE-19629
URL: https://issues.apache.org/jira/browse/IGNITE-19629
Project: Ignite
Issue Type: Bug
Components: general
Affects Versions: 2.15
Reporter: Nikolay
In apache ignite 2.15 CacheMetricsMXBean was removed. Legacy metrics system
could give us some valuable metrics regarding cache's health. For example,
[isValidForReading|https://ignite.apache.org/releases/2.14.0/javadoc/org/apache/ignite/mxbean/CacheMetricsMXBean.html#isValidForReading–]
[isValidForWriting|https://ignite.apache.org/releases/2.14.0/javadoc/org/apache/ignite/cache/CacheMetrics.html#isValidForWriting–]
In the latest version of apache ignite we miss such metrics, it is hard to
understand now when there is a lost_partition situation in caches. Previously
these metrics were telling us to go and fix such caches. Can we bring them back?
