Siegfried, This is a wonderful find. The second presentation is a nice write-up of a large number of free tools. The first presentation prompts a question - did you add custom request handlers/code to automate determination of best user search terms? Did any of your custom work end-up in Solr? Thank you so much,
Dan P.S. - your first presentation takes me back to seeing "Angrif der Klonkrieger" in Berlin after a conference - Hayden Christensen was less annoying in German, because my wife and I don't speak German ;) I haven't thought of that in a while. -----Original Message----- From: Siegfried Goeschl [mailto:sgoes...@gmx.at] Sent: Saturday, April 04, 2015 4:54 AM To: solr-user@lucene.apache.org Subject: Re: Measuring QPS Hi Dan, I’m using JavaMelody for my SOLR production servers - gives you the relevant HTTP stats (what’s happening now & historical data) plus JVM monitoring as additional benefit. The servers are deployed on Tomcat so I’m of little help regarding Jetty - having said that * you need two Jars (javamelody & robin) * tinker with web.xml Here are two of my presentations mentioning JavaMelody (plus some other stuff) http://people.apache.org/~sgoeschl/presentations/solr-from-development-to-production-20121210.pdf <http://people.apache.org/~sgoeschl/presentations/solr-from-development-to-production-20121210.pdf> http://people.apache.org/~sgoeschl/presentations/jsug-2015/jee-performance-monitoring.pdf <http://people.apache.org/~sgoeschl/presentations/jsug-2015/jee-performance-monitoring.pdf> Cheers, Siegfried Goeschl > On 03 Apr 2015, at 17:53, Shawn Heisey <apa...@elyograg.org> wrote: > > On 4/3/2015 9:37 AM, Davis, Daniel (NIH/NLM) [C] wrote: >> I wanted to gather QPS for our production Solr instances, but I was >> surprised that the Admin UI did not contain this information.
