Nikolay created IGNITE-19629:

             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?
