--- Comment #6 from Antoine "hashar" Musso <[email protected]> --- With Lucene, I guess we did a simple round robin load balancing. The high latency queries were probably hitting a single overloaded search server. I have no idea how ElasticSearch handles load balancing of requests across search servers. It might be using a smarter load balancing algorithm. The dashboard at http://gdash.wikimedia.org/dashboards/searchlatency/ is defined by operations/puppet.git in files/gdash/dashboards/searchlatency/ files. The graphs are based on the statsd metric MediaWiki.LuceneSearchSet.newFromQuery. It should be fairly easy to add similar graphs if the ElasticSearch extension provides a similar wfProfileIn() call. -- You are receiving this mail because: You are the assignee for the bug.
