Access to view stats
by Magnus Manske 16 Jun '13

16 Jun '13

Hi all, as you might know, I have a few GLAM-related tools on the toolserver. Some are updated once a month, some can be used live, but all are in high demand by GLAM institutions. Now, the monthly updated stats have always been slow to run, but did almost grind to a halt recently. The on-demand tools have stalled completely. All these tools get their data from stats.grok.se, which works well but not really high-speed; my on-demand tools have apparently been shut out recently because too many people were using them, DDOSing the server :-( I know you are working on page view numbers, and for what I gather it's up-and-running internally already. My requirements are simple: I have a list of pages on many Wikimedia projects; I need view counts for these pages for a specific month, per-page. Now, I know that there is no public API yet, but is there any way I can get to the data, at least for the monthly stats? Cheers, Magnus

Skin and active editor correlation
by Matthew Flaschen 28 Mar '13

28 Mar '13

There's discussion at https://bugzilla.wikimedia.org/show_bug.cgi?id=44448 about how skin usage correlates with who's an active editor. It would be great to know what percentage of active editor (5+ edits in the main namespace) uses each skin on English Wikipedia. Perhaps for the last three months. Matt Flaschen

RFC: Tab as field delimiter in logging format of cache servers
by Diederik van Liere 21 Mar '13

21 Mar '13

Apologies for crossposting Heya, The Analytics Team is planning to deploy "tab as field delimiter" to replace the current space as fielddelimiter on the varnish/squid/nginx servers. We would like to do this on February 1st. The reason for this change is that we need to have a consistent number of fields in each webrequest log line. Right now, some fields contain spaces and that require a lot of post-processing cleanup and slows down the generation of reports. What is affected and maintained by Analytics * udp-filter already has support for the tab character * webstatscollector: we compiled a new version of filter to add support for the tab character * wikistats: we will fix the scripts on an ongoing basis. * udp2log: we have a patch ready for inserting sequence numbers separated by tab. In particular, I would like to have feedback to three questions: 1) Are there important reasons not to use tab as field delimiter? 2) Are there important pieces of logging that expect a space instead of a tab and that need to be fixed and that I did not mention in this email? 3) Is February 1st a good date to deploy this change? (Assuming that all preps are finished) Best, Diederik

wikidata stats
by Ed Summers 01 Feb '13

01 Feb '13

Hi all, There has been some recent discussion [1] on wikidata-l about making sure wikidata.org page views are part of the stats that are being collected at stats.grok.se. I did a quick check to see if page views on www.wikidata.org were showing up, and they don't appear to be. curl --silent http://dumps.wikimedia.org/other/pagecounts-raw/2013/2013-01/pagecounts-201… | zcat - | egrep ' Q\d+ ' de Q100 2 15502 de Q5 2 95286 en Q0 1 7815 en Q1 6 70841 en Q10 2 32918 en Q101 1 7709 en Q102 1 8128 en Q107 1 26148 en Q11 1 387 en Q19 2 14304 en Q2 7 44454 en Q3 1 8624 en Q35 1 22856 en Q4 3 40588 en Q4000 2 28866 en Q5 3 16698 en Q612 1 7152 en Q6600 2 29929 en Q7 2 16604 en Q9450 2 59452 fr Q4 2 24352 fr Q400 1 17339 hu Q10 3 105745 ja Q0 1 8685 ja Q10 36 781763 ja Q4 1 8873 ja Q400 1 25208 ko Q3 1 22350 nl Q65 2 24562 ru Q10 1 31355 ru Q4000 1 11140 sv Q10 1 365 zh Q1 1 10950 zh Q10 2 17738 Does anyone have any idea how to get stats.grok.se updated? I think I've seen from previous conversation here that an alternate source for stats is being created? Is there any information available on how to use that if it's available yet? //Ed [1] http://lists.wikimedia.org/pipermail/wikidata-l/2013-January/001646.html

Return of Wikihadoop
by Diederik van Liere 28 Jan '13

28 Jan '13

Heya, Last week I resurrected Wikihadoop from the Summer of Research 2011 when we wrote a Hadoop-based input parser for bzipped XML dumps of Wikipedia and the ability to create diffs between revisions. This work was mainly done by Yusuke Matsubara, Aaron Halfaker and Fabian Kaelin. This is working again and if you have input / suggestions on how to expose this data, then please let me know! Best, Diederik

Issues with Emery
by Diederik van Liere 28 Jan '13

28 Jan '13

Heya, Since yesterday afternoon we have been having intermittent packetloss issues with Emery. Ori and myself wrote yesterday a simple patch to enable sampling on two filters to reduce the workload. That seemed to work however this morning packetloss came back. Paravoid pointed out that it was probably due to the fact that Emery was running for 208 days and that older versions of the kernel start doing weird things. Rebooting Emery seemed to have resolved the issue and we are planning to upgrade to Precise soon. Best, Diederik

Access to view stats
by Brian Keegan 25 Jan '13

25 Jan '13

I wanted to follow up and second on Magnus' December request<http://lists.wikimedia.org/pipermail/analytics/2012-December/000272.html>for more usable way to access page view stats. Mining these stats is attracting an increasing amount of attention from researchers ( http://www.l3s.de/~kanhabua/papers/ECIR2013-WikiEvents.pdf, http://arxiv.org/pdf/1212.5943v1.pdf, http://arxiv.org/pdf/1211.0970.pdf) even as the current approaches for extracting them from stats.grok.se or the dumps are slow and inhumane (respectively). I'm also interested in looking at bursts of pageview activity on articles and then examining the extent to which this pageview activity diffuses over the local wiki-link network. I suspect this has strong implications for understanding patterns of editing activity; namely, editing activity may be non-trivially coupled with sudden attention to articles that are a few degrees of separation away. I'd be happy to chat with folks inside or outside of WMF about getting access to the relevant view stats and beginning such an analysis. Best, Brian

The Uniﬁed Logging Infrastructure for Data Analytics at Twitter
by Dario Taraborelli 22 Jan '13

22 Jan '13

http://arxiv.org/pdf/1208.4171.pdf This is a pretty interesting and accessible description of best practices and design decisions driven by practical problems they had to solve at Twitter in the area of client-side event logging, funnel analysis, user modeling. E3: check out section "3.2 Client Events" in particular, which is quite relevant to EventLogging. Dario

getting Wikisource added to the page-view data logs
by Sumana Harihareswara 22 Jan '13

22 Jan '13

I saw this discussion: https://en.wikipedia.org/wiki/User_talk:Emw#Stats thanks to Andrea Zanni (cc'd), who would like to add Wikisources to this tool: http://toolserver.org/~emw/wikistats/?p1=Coupling_%28computer_programming%2… In order for that to happen, Emw said, we'd need to add an "identifier for that project in the raw page-view data". How feasible is that? Thanks. -- Sumana Harihareswara Engineering Community Manager Wikimedia Foundation

Hey everyone! Pageview counts for the wikivoyage project are availabe on dumps.wikimedia.org as part of the regular hourly article and project counts files. The first file that contains them has the timestamp " 20130116-160001<http://dumps.wikimedia.org/other/pagecounts-raw/2013/2013-01/projectcounts-…> " Example file http://dumps.wikimedia.org/other/pagecounts-raw/2013/2013-01/projectcounts-… and search for ".voy". If you run into any issues please let us know or file a bug on bugzilla (Analytics -> webstatscollector). Best regards, Diederik
