Elasticsearch metrics moving to Prometheus
by Guillaume Lederrey 14 Dec '17

14 Dec '17

Hello! We are moving all our metrics from Graphite [1] to Prometheus [2]. See the master task for some details [3]. We are now working on porting all those metrics for elasticsearch [4]. This means that we'll need to update our dashboards to start using those new metrics. During the transition, I'll keep the existing dashboards, but create a copy to migrate the metrics. For example, the "Elasticsearch Percentiles" [5] dashboard has a copy named "Elasticsearch Percentiles - Prometheus" [6]. Those new dashboards should behave in just the same way, but please let me know if you find any incoherence! Have fun!

OpenSearch Return Value
by Gheorghe Postelnicu 11 Dec '17

11 Dec '17

Hello, I am writing with a question regarding the OpenSearch API, which is super useful for extracting summary information about a page. For a lot of pages, the return items contain: - text - url - description - image e.g. https://en.wikipedia.org/w/api.php?action=opensearch&search=Angela%20Merkel… However, there are quite a few cases where the image property is missing, although the page features an image in the infobox. Example: https://en.wikipedia.org/w/api.php?action=opensearch&search=Solaris_(2002_f… In cases where the opensearch extension doesn't return an image, is there another API which allows extracting the infobox image if one is present? Many thanks in advance for the help, Gheorghe

Commons Fulltext Search
by Gheorghe Postelnicu 07 Dec '17

07 Dec '17

Hello, First, many thanks for maintaining this API! I am writing as I am having trouble using the full text search API on Commons. Namely, I would like to get the following list back via the API: https://commons.wikimedia.org/w/index.php?title=Special:Search&profile=imag… however the full text search doesn't produce the same results when using the API: https://commons.wikimedia.org/w/api.php?action=query&list=search&srsearch=d… A suggestion to nudge me in the right direction would be greatly appreciated. Many thanks in advance for the help. Best regards, Gheorghe

Logstash upgrade coming up
by Guillaume Lederrey 07 Dec '17

07 Dec '17

Hello! Our logstash servers are the last servers to upgrade to elasticsearch 5.5.2. I'm planning to do this upgrade on Thursday December 7, between 9:00 and 10:00 UTC (10:00 to 11:00 CET, 01:00 to 02:00 PST). Testing on labs went well, so I'm not expecting any issue. Now that all servers are behind LVS, we should not even loose a single message. That being said, there is a risk. If you see disapearing log messages during that period, please let me know! Have fun!
