Subject [jira] Commented: (SOLR-1750) SystemStatsRequestHandler - replacement for stats.jsp
Date Thu, 04 Feb 2010 00:58:27 GMT

    [ https://issues.apache.org/jira/browse/SOLR-1750?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12829354#action_12829354

Simon Rosenthal commented on SOLR-1750:
---------------------------------------


+1 on SolrStatsRequestHandler

You might want to consider either omitting or making optional the Lucene Fieldcache stats;
they can often be *very* slow to be generated  ( see  http://www.lucidimagination.com/search/document/5ba908577d2e4c25/stats_page_slow_in_latest_nightly#2f40166c25f9bfa0
). One use case for this request handler that I can see is high frequency (every few seconds)
monitoring as part of performance testing,  for which a fast response is pretty mandatory.

> stats.jsp is cool and all, but suffers from escaping issues, and also is not accessible
from SolrJ or other standard Solr APIs.
> Here's a request handler that emits everything stats.jsp does.
> For now, it needs to be registered in solrconfig.xml like this:
> {code}
>     <requestHandler name="/admin/stats" class="solr.SystemStatsRequestHandler" />
> {code}
> But will register this in AdminHandlers automatically before committing.
