Gary Helmling updated HBASE-1722:
---------------------------------
Attachment: hbase-bin.patch
Here's a patch for the bin/hbase and conf/hbase-env.sh scripts and
conf/hadoop-metrics.properties, adding placeholder configurations to ease the
process of enabling JMX monitoring. If the conditional checking in bin/hbase
for a "start" action is too weird though, feel free to skip these changes. The
config is documented in the metrics.xml patch. This just provides a bit more
guidance for enabling.
> 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: 0.20.1

> Attachments: hbase-bin.patch, jmx_metrics-0.19.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.
