The elasticsearch servers that run logstash.wikimedia.org will soon be upgraded from 1.7 to 2.3. As part of this upgrade we also need to upgrade kibana (the web interface that runs on logstash.wikimedia.org). The current version uses elasticsearch features that have been long deprecated (since 1.4) and as of 2.0 have been removed. I've setup a test environment in the beta cluster running this new version of elasticsearch along with the new version of kibana.
Be warned, kibana 4 is a complete rewrite. It needs to be evaluated for our purposes and we need to make sure it does what we need. I've recreated most of the dashboards that were linked from the homepage of logstash-beta.wmflabs.org to help with the evaluation. The first few took a short while, but due to the way kibana re-uses visualizations it became a good bit faster/easier after that. The main feature i've noticed missing from our old dashboards is the trends panel. This is the part that told you how the volume of messages compared to the previous hour/day/week/etc. There is a long standing github issue about replacing this functionality but it has been stalled out. I don't personally use that part of the visualization much, but perhaps you do? Please try it out, and give some feedback. https://kibana.wmflabs.org/ Erik B _______________________________________________ Wikitech-l mailing list Wikitech-l@lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikitech-l
