Gary Helmling updated HBASE-1722:
---------------------------------
Attachment: jmx_support-trunk.patch
Here's a patch against current trunk. This one was generated with git, but I
was able to test apply cleanly with patch -p1.
This one was even easier thanks to MetricsDynamicMBeanBase in hadoop 0.20! I
was able to drop the need for separate interfaces and pass through accessors
for each metric.
I'll put up some docs on enable JMX monitoring on the wiki. For remote
monitoring this may require some tweaks to hbase-env.sh and the hbase shell
script -- like separating out option vars for master vs. regionservers.
> 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: 0.19.4
>
> 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.
