Subject [jira] [Updated] (HBASE-15144) Procedure v2 - Web UI displaying Store state
Date Wed, 24 Feb 2016 15:24:18 GMT

     [ https://issues.apache.org/jira/browse/HBASE-15144?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Samir Ahmic updated HBASE-15144:
    Attachment: HBASE-15144_v3.patch

Here is new patch with sync stats stored in circular buffer with size 10. Regarding WAL roll
time i think is self explanatory we are displaying time when last roll time was happened and
when next one will occur. Only alternative that i can think of is to show list of times when
roll happened. Also we can add paragraph under "Procedure WAL State" table explaining in more
details how procedure Store works and what some of parameters mean  like we do for regions
in "Regions" table.

> The procedure webui page should show information about the WALProcedureStore.
>  * number/list/size of WALs active
>  * we may extract the "Sync wait %s, slotIndex=%s , totalSynced=%s (%s/sec)" that today
is only in LOG.trace()
>  * we have a getMillisToNextPeriodicRoll() and getMillisFromLastRoll() if anyone want
to see that
