> Key: HBASE-7057
> URL: https://issues.apache.org/jira/browse/HBASE-7057
> Project: HBase
> Issue Type: Improvement
> Components: metrics, UI
> Affects Versions: 0.96.0
> Reporter: Elliott Clark
> Priority: Critical
> Labels: noob
> Fix For: 0.98.0

>
> 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.
