    [ https://issues.apache.org/jira/browse/OAK-364?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13893392#comment-13893392 ] 

Michael Dürig commented on OAK-364:
-----------------------------------

We could build on my work on OAK-1338 and expose such metrics as time series.

> As we start looking more at performance benchmarks and more generally once Oak starts to get deployed in production environments, it would be really useful if we provided a collection of useful performance metrics in a way that's easy to access.
> For example it would be good to have metrics on at least the following:
> * Time per MicroKernel read
> * Hit/Miss ratio of the NodeState cache
> * Time per MicroKernel commit/merge
> * Time per each commit hook
> * Time per query
> * etc.
