Store Server Load in a Table Key: HBASE-7057 URL: https://issues.apache.org/jira/browse/HBASE-7057 Project: HBase Issue Type: Improvement Components: metrics, UI Affects Versions: 0.95.2 Reporter: Elliott Clark Priority: Critical Labels: beginner Currently the server hart beat sends over server load and region loads. This is used to display and store metrics about a region server. It is also used to remember the sequence id of flushes. This should be moved into an HBase table. * Allow the last sequence id to persist over a master restart. * That would allow the balancer to have a more complete picture of what's happened in the past. * Allow tools to be created to monitor hbase using hbase. * Simplify/remove the heartbeat. -- This message was sent by Atlassian JIRA (v6.3.4#6332)

I have to problem looking at this but it would have to be after HBASE-13992. I almost have a patch for HBASE-13992. Hopefully tonight or tomorrow.

If so I would love to give it a try. If so Elliott can I ping you for 5 minutes to make sure I get your visual correct on this?

We could let it TTL out after an hour so we didn't keep too much around (or after an hour do the TSDB rollups if wanted) + A TSDB like query page for looking at the cluster over time would be sweet. + We should be careful to ensure we do not repeat the mistakes of the distant past when we used to keep a region history table into which we noted region transition; the problem there was our trying to record events like close when say, the cluster was going down, and the table we were trying to write would be down -- the writer could hang This seems like a small thing to do that could improve usability alot.
