Gary Helmling updated HBASE-1722:
---------------------------------
Attachment: metrics_docs_0.19.patch
Here is a patch for metrics.xml against 0.19. The only change is the domain
for where the MBeans appear (hadoop.dfs) -- this is controlled by the Hadoop
MBeanUtil class.
Again if anything's missing or additional information would be useful, let me
know.
> Add support for exporting HBase metrics via JMX
> -----------------------------------------------

> Key: HBASE-1722
> URL: https://issues.apache.org/jira/browse/HBASE-1722
> Project: Hadoop HBase
> Issue Type: Improvement
> Components: ipc, master, regionserver
> Affects Versions: 0.19.3
> Reporter: Gary Helmling
> Priority: Minor
> Fix For: 0.21.0

> Attachments: jmx_metrics-0.19.patch, jmx_support-trunk.patch,

> Current HBase metrics collection and reporting (for the 0.19 releases at
> least) doesn't seem to export any of the metrics as MBeans via JMX.
> This patch adds JMX MBean support for reporting metrics collected in 3 areas:
> * org.apache.hadoop.hbase.ipc.HBaseRpcMetrics
> * org.apache.hadoop.hbase.master.metrics.MasterMetrics
> * org.apache.hadoop.hbase.regionserver.metrics.RegionServerMetrics
> This patch is only against the 0.19 branch, as the metrics API seems to have
> changed a bit in Hadoop 0.20, including adding support for dynamic MBeans.
> I'll add a patch reworked for trunk shortly.
