Walter Underwood commented on SOLR-4735: ---------------------------------------- Anybody using the CodaHale metrics.jetty9.InstrumentedHandler? It looks a lot like something we built for our own use with Solr 4. http://metrics.dropwizard.io/3.1.0/manual/jetty/ http://metrics.dropwizard.io/3.1.0/apidocs/com/codahale/metrics/jetty9/InstrumentedHandler.html wunder > Improve Solr metrics reporting > ------------------------------ > > Key: SOLR-4735 > URL: https://issues.apache.org/jira/browse/SOLR-4735 > Project: Solr > Issue Type: Improvement > Reporter: Alan Woodward > Assignee: Alan Woodward > Priority: Minor > Attachments: SOLR-4735.patch, SOLR-4735.patch, SOLR-4735.patch > > > Following on from a discussion on the mailing list: > http://search-lucene.com/m/IO0EI1qdyJF1/codahale&subj=Solr+metrics+in+Codahale+metrics+and+Graphite+ > It would be good to make Solr play more nicely with existing devops > monitoring systems, such as Graphite or Ganglia. Stats monitoring at the > moment is poll-only, either via JMX or through the admin stats page. I'd > like to refactor things a bit to make this more pluggable. > This patch is a start. It adds a new interface, InstrumentedBean, which > extends SolrInfoMBean to return a > [[Metrics|http://metrics.codahale.com/manual/core/]] MetricRegistry, and a > couple of MetricReporters (which basically just duplicate the JMX and admin > page reporting that's there at the moment, but which should be more > extensible). The patch includes a change to RequestHandlerBase showing how > this could work. The idea would be to eventually replace the getStatistics() > call on SolrInfoMBean with this instead. > The next step would be to allow more MetricReporters to be defined in > solrconfig.xml. The Metrics library comes with ganglia and graphite > reporting modules, and we can add contrib plugins for both of those. > There's some more general cleanup that could be done around SolrInfoMBean > (we've got two plugin handlers at /mbeans and /plugins that basically do the > same thing, and the beans themselves have some weirdly inconsistent data on > them - getVersion() returns different things for different impls, and > getSource() seems pretty useless), but maybe that's for another issue. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
