stack commented on HBASE-17436:
-------------------------------
[~gubjanos] Trying to understand. Per region, you want to show its state in
JMX? The state is transitory, and up in ZK and hbase:meta, and now we'd publish
it over JMX too?
How are you tihnking of consuming these new metrics? Via a JMX reader or via
/metrics JSP which would take the JMX and then dump it out as JSON?
bq. Rohan Pednekar and I were looking at a case where the count displayed under
Other Regions was high (~1200). Since the table page just maintains a count
instead of List of region names, it is very difficult for user to determine
which regions belong to this category.
Did you consider adding more columns to the main page? When you click on the
table page, it shows a listing of its regions. Adding a column on its state
would fit naturally here? Could add sorting by columns and then sort regions by
the type of transition they are in? What for the case when there !M regions?
We push to JMX on a period regardless as to whether they are being looked at or
not. At least display in the page is on a poll basis. When 1M regions, we
should probably paginate. See elsewhere in the UI where you can ask for data as
JSON. That might be more consumable by dashboards and tooling -- and probably
cheaper than going via JMX. What you think?
