Re: Anybody uses Solr JMX?
Hi Paul, There are lots of people/companies using SPM for Solr/SolrCloud and I don't recall anyone saying SPM agent collecting metrics via JMX had a negative impact on Solr performance. That said, some people really dislike JMX and some open source projects choose to expose metrics via custom stats APIs or even files.

Re: Anybody uses Solr JMX?
Lots of organizations use monitoring Solr's JMX for dashboards/healthchecks, all that sort of thing. AFAIK they're very light-weight.

Re: Anybody uses Solr JMX?
Hello Otis, this looks like an excellent idea! I'm in need of that, erm… last week and probably this one too. Is there not a risk that reading certain JMX properties actually hogs the process? (or is it by design that MBeans are supposed to be read without any lock effect?). thanks for the hint. paul On 6 mai 2014, at 04:43, Otis Gospodnetic wrote: > Alexandre, you could use something like > http://blog.sematext.com/2012/09/25/new-tool-jmxc-jmx-console/ to quickly > dump everything out of JMX and see if there is anything there Solr Admin UI > doesn't expose.

Another option to get JMX data from Solr to Graphite <http://graphite.wikidot.com/> or Ganglia <http://ganglia.sourceforge.net/> using jmxtrans https://github.com/jmxtrans/jmxtrans/wiki On Wed, Aug 6, 2014 at 3:09 AM, rulinma wrote: > good job . > > > > -- > View this message in context: > http://lucene.472066.n3.nabble.com/Anybody-uses-Solr-JMX-tp4134598p4151408.html > Sent from the Solr - User mailing list archive at Nabble.com. >

Re: Anybody uses Solr JMX?
Alexandre, you could use something like http://blog.sematext.com/2012/09/25/new-tool-jmxc-jmx-console/ to quickly dump everything out of JMX and see if there is anything there Solr Admin UI doesn't expose. I think you'll find there is more in JMX than Solr Admin UI shows.

JMX is multi-purpose. So, in principle, it can offer considerably more. I've seen discussions about quite many JMX variables about the activity of the Garbage Collector (e.g. young-generation, …) which I can't remember having seen in the Admin UI. The advantage of JMX is the interface and what you can do with it. For example plotting values is not there in the admin UI and it really can help to make a difference into detecting, say, the cause of sudden bursts. paul
Re: Anybody uses Solr JMX?
Thank you everybody for the links and explanations. I am still curious whether JMX exposes more details than the Admin UI? I am thinking of a troubleshooting context, rather than long-term monitoring one. Regards, Alex.

Re: Anybody uses Solr JMX?
Also, Zabbix and Nagios does read from JMX. Zabbix has a "prototype" for SOLR which is a simple way to gather an amount of data from solr and do, for example, archiving and plotting of cache values. paul Le 5 mai 2014 à 04:37, Ahmet Arslan a écrit : > Hi, > > It looks like JMX is a standard way to expose statistics etc. For easy > integration with existing jmx monitoring tools. > > http://sematext.com/spm/ and http://newrelic.com read jmx data for instance. > > Ahmet > > On Monday, May 5, 2014 4:39 AM, Alexandre Rafalovitch > wrote: > > I have religiously kept statement in my solrconfig.xml, thinking > it was enabling the web interface statistics output. > > But looking at the server logs really closely, I can see that JMX is > actually disabled without server present.

Re: Anybody uses Solr JMX?
Hi, It looks like JMX is a standard way to expose statistics etc. For easy integration with existing jmx monitoring tools. http://sematext.com/spm/ and http://newrelic.com read jmx data for instance.
