Subject [jira] [Commented] (OAK-7021) Collect DocumentStore stats as part of status zip
Date Mon, 04 Dec 2017 09:49:00 GMT

    [ 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

void dumpStats(PrintWriter printWriter)

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

>             Project: Jackrabbit Oak

>          Components: documentmk
>            Reporter: Chetan Mehrotra
>             Fix For: 1.8
> 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
