Subject [jira] [Updated] (OAK-4097) Add metric for FileStore journal writes
Date Tue, 09 Aug 2016 08:04:20 GMT

     [ https://issues.apache.org/jira/browse/OAK-4097?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Andrei Dulceanu updated OAK-4097:
    Attachment: OAK-4097-03.patch

[~mduerig] I followed your advice regarding manually calling {{FileStore.flush()}} and converted
my IT scenario into a plain unit test in {{FileStoreStatsTest}}, patch attached. 

If you are ok with the approach, I think we can finally close this one. Thanks!

> TarMK flush thread should run every 5 secs and flush the current root head to journal.log.
It would be good to have a metric to capture the number of runs per minute
> This would help in confirming if flush is working at expected frequency or delay in acquiring
locks is causing some delays
