Re: HBASE-4089 HBASE-4147 - on the topic of ops output

Hi, I'm for publishing all performance metrics in JMX (in addition to exposing it wherever else you guys decide).  That's because JMX is probably the easiest for our SPM for HBase [1] to get to HBase performance metrics and I suspect we are not alone. Otis [1]

Re: Performance metrics Hbase

U think lots of people use Ganglia...and Ambari uses it for example. We use our own SPM for HBase monitoring (see url in my sig below), which incidentally runs on top of HBase itself. :) Otis Solr ElasticSearch Support http://sematext.com/ On May 24, 2013 1:49 PM, Alvaro Garcia Recuero

Re: Extending HBase Metrics Framework

Hi, Not 100% sure if I understand what you are after, but it sounds like you are OK/want to modify HBase source code and add tracking of some metric that is currently not being tracked. Could you use Coda Hale Metric lib for that then?  Any metric you capture with it can then go into JMX or

Exposing config properties via JMX?

Hi, For our HBase Performance Monitoring tool we had to do some bytecode instrumentation to catch the following 2 properties in order to be able to graph them on our MemStore graphs: * hbase.regionserver.global.memstore.upperLimit * hbase.regionserver.global.memstore.lowerLimit Would it make

For HBase compactions - Lucene's IO impact reduction code

Hi, Here is something that may be of interest to HBase: Lucene 4.0.0-Alpha was recently released.  Mike McCandless, sne of the Lucene developers, wrote a really nice post about new things in this version of Lucene.  The part that I think is interesting for HBase, and that HBase devs may want

Re: deprecating (old) metrics in favor of metrics2 framework

+1 for deprecating and moving to metrics2 faster. I'd normally make the same argument about deprecating that Lars H. made, but I think current HBase metrics really need improvement, so if I had voting power I'd vote to drop old stuff and move to metrics2 ASAP. Otis - Original Message -
