["Chetan Mehrotra (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/OAK-7021?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16276542#comment-16276542 ] 

Chetan Mehrotra commented on OAK-7021:
--------------------------------------

[~mreutegg] [~catholicon] [~julian.reschke@gmx.de] Probably we can add a generic method to DocumentStore

{noformat}
void dumpStats(PrintWriter printWriter)
{noformat}

And have implementation for both stores. This can then be used by an InventoryPrinter implementation to include this info with config zip. Also same can be exposed via JMX

> Many times while investigating issue we request customer to provide Mongo db stats. It would be useful if there is an InventoryPrinter for DocumentStore which dumps various stats
> Some useful stats would be
> * Number of entries in "nodes" collection
> * Index memory size
> * Node collection size on disk
> * Number of cluster members which are active
> See OAK-6179 for inventory printer related details
