Missing Country Names
by Atul Vaidya 11 Oct '14

11 Oct '14

Thank you Erik. I see that the squid browser reports for the months of August and September of this year now have country data. However, the data between the months of October 2013 and July 2014 remain unchanged. Also, with those data I notice that my browser reports that it was unable to get jquery-1.3.2.min.js and jquery.tablesorter.js. Atul

Thank you Eric. I look forward to seeing those reports in their corrected for in due course. The fact that Wikimedia reports contain actual visitor numbers rather than mere percentages make them a really rich source of information that can be analyzed in a host of different ways - but not without the country names!

eventlogging largest tables
by Sean Pringle 10 Oct '14

10 Oct '14

Hi :-) These are the largest Eventlogging tables on m2-master: 145G MobileWebClickTracking_5929948.ibd 94G PageContentSaveComplete_5588433.ibd 61G MediaViewer_8572637.ibd 57G MediaViewer_8245578.ibd 30G MultimediaViewerNetworkPerformance_7917896.ibd 29G MediaViewer_8935662.ibd 24G MobileWikiAppToCInteraction_8461467.ibd Are these sizes roughly expected? Anything we can discard or reduce? Where did the discussion on purging data end up? No immediate problems here, just rattling cages :-) BR /s -- DBA @ WMF

Making webstatscollector stop counting redirects at the HTTP level
by Christian Aistleitner 10 Oct '14

10 Oct '14

Hi, One of the longstanding issues with Webstatscollector is that it counts redirects at the HTTP level. So for example [1]: - Requesting a page with a lower case first letter, - Requesting a page from the desktop site on a mobile device, or - Requesting to www.wikipedia.org (first part is www, not a language) causes two requests to the caches, and webstatscollector counts both, although actually only a single page is shown to the user. Thereby too high numbers get reported. Since we're about the deploy a fix for webstatscollector tomorrow anyways, and this double counting should not be too hard to fix, let's get it fixed too. If you see value in counting redirects, please let us know soonish, as I'll try to get the changes into tomorrow's deployment. Sorry for the short notice, Christian [1] See the corresponding bug 71790 https://bugzilla.wikimedia.org/show_bug.cgi?id=71790 for concrete examples. -- ---- quelltextlich e.U. ---- \\ ---- Christian Aistleitner ---- Companies' registry: 360296y in Linz Christian Aistleitner Kefermarkterstrasze 6a/3 Email: christian(a)quelltextlich.at 4293 Gutau, Austria Phone: +43 7946 / 20 5 81 Fax: +43 7946 / 20 5 81 Homepage: http://quelltextlich.at/ ---------------------------------------------------------------

Gerrit permissions for group “Analytics” on “analytics/*” projects
by Christian Aistleitner 07 Oct '14

Hi, people from gerrit's “Analytics” group [1] currently hold * Push (including Force Push) * Push Merge Commit * Forge Author Identiy * Forge Committer Identity permissions on “analytics/*” projects in gerrit. But those permissions got and get in the way one way or the other. Do we need those permissions for our repos? If no one objects, I'll start removing them on 2014-04-28.

Hi, the machine that hosts stats.wikimedia.org datasets.wikimedia.org is experiencing problems, and hence the above sites are currently unavailable. Investigation is still going on. We're tracking the issue at https://bugzilla.wikimedia.org/show_bug.cgi?id=71686 Sorry for the inconveniences, Christian -- ---- quelltextlich e.U. ---- \\ ---- Christian Aistleitner ---- Companies' registry: 360296y in Linz Christian Aistleitner Kefermarkterstrasze 6a/3 Email: christian(a)quelltextlich.at 4293 Gutau, Austria Phone: +43 7946 / 20 5 81 Fax: +43 7946 / 20 5 81 Homepage: http://quelltextlich.at/ ---------------------------------------------------------------

Adventures in Clusterland 2014-09-22--2014-09-28
by Christian Aistleitner 04 Oct '14

04 Oct '14

Hi, in the week from 2014-09-22–2014-09-28 Andrew, Jeff, and I worked on the following items around the Analytics Cluster and Analytics related Ops: * Accessing HDFS through plain file system * Bringing Webstatscollector to Hive * Presentation of Sqoop * Using kafkatee to generate TSVs * Packetloss alerts (Bug 71116) (details below) Have fun, Christian * Accessing HDFS through plain file system As by-product of preparing to get cluster generated datasets to the webservers, hdfs got (read-only) mounted on stat1002 into the plain file system at /mnt/hdfs. So you can now for example access the HDFS data files directly from /mnt/hdfs/wmf/data on stat1002. Also, you no longer need to setup ssh tunnels and some such to get to your logs. You can now just look at them from /mnt/hdfs/var/log/hadoop-yarn/apps/ as plain files, and grep, tail, ... them. * Bringing Webstatscollector to Hive The webstatscollector reimplementation in Hive got merged and is producing data since 2014-09-23. This implementation is ** no longer subject to the contiuous packet loss on udp2log [1], ** can rerun jobs if needed, ** contains pagecounts for all sites. While researchers could already use the data on stat1002, legal sign-off for publishing it to the public was still missing. (We got it in the meantime, so publishing is imminent. But that will be reported in the next weekly email) * Presentation of Sqoop More research around how to get MediaWiki databases into Hadoop was done, and Sqoop is the tool of choice at this point in time. The current possibilities of Sqoop and how one can use it to import data into Hadoop has been demoed and discussed with researchers. * Using kafkatee to generate TSVs Discussions around kafkatee are still going on. But there is no solution yet. * TSV generation through Hive Since kafkatee issues are not yet resolved, we followed up on previous week's initial screening by doing a more thorough check on the feasibility of generating the TSVs through Hive instead of kafkatee. We cannot only cover the immediately needed TSVs for our researches, but also cover the glam and fundraising tsvs. So we could do fully without kafkatee. Looking more closely at the implementation blockers, it seems there is only a geocoding blocker. But we can overcome it with a little Java coding. We gave it a shot with the sampled-1000, mobile-sampled-100, and zero tsvs, vetted the Hive-produced data and it worked smoothly. So the way forward is solid and paved, in case kafkatee issues cannot get resolved soonish. * Packetloss alerts (Bug 71116) On 2014-09-20 there were alerts around packet loss on udp2log. But they turned out to be an artifact of on ULSFO outage [2]. [1] This is the first dataset that's coming out of the cluster, and the cluster still has minor hiccups from time to time. But data quality and reliability is already several orders of magnitude better than udp2log has ever been. So it's already the prefered source for datasets.
