[jira] [Updated] (OAK-3850) Collect and expose Persistent Cache stats

     [ https://issues.apache.org/jira/browse/OAK-3850?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Teodor Rosu updated OAK-3850:
-----------------------------
    Attachment: OAK-3850-v0.patch

I attached a quick draft just to share the exposed stats and mbean interface I was thinking of. This only covers NodeCache stats for now.

[~chetanm] [~mreutegg] Could you please take a quick look? Also could you link this to OAK-3814?

I initially thought of exposing as CacheStatsMbean, but I don't think it's the best choice ( no TimeStats, non trivial methods like getEvictionCount and others ).
