Analytics/Metric definitions

Background: Both the community and WMF have been using a number of metrics to keep track of the health of our projects. This page keeps track of commonly used metrics and their definition. It is our goal to standardize these definitions and to make sure that they are consistently applied. Also it is important to use different terms for different metrics so as to avoid confusion. We hope to make the distinction between related metrics clear and easy to comprehend.

Content
(dumps.wikimedia.org t.b.a.)

Content served
We need to make a distinction between page views and file requests. For both concepts reports are featured on stats.wikimedia.org

Page views
Derived from webstatscollector, which produces hourly aggregates based on incoming squid logs.


 * Relevant filter criteria
 * The url in a logline contains /wiki/. This excludes /w/index.php? and SpecialPages.
 * Not all public wikimedia projects are counted (e.g. foundation wiki).
 * Any article namespace qualifies (unlike the dump based reports (see 'Content' above)).

File requests
Many reports provide different breakdowns of files served by wikimedia squids. Breakdown by mime type, origin, destination, browser, OS etc. Also breakdown of edits or views by region, country, period, etc.


 * Relevant filter criteria
 * Any html request is counted in relevant reports, based on the supplied mime type 'text/html'. This includes counting special pages, pages requested using /w/index.php?.


 * Known issues:
 * Error pages are counted as html requests.
 * Mobile traffic does not yet supply mime type, this is inferred from url in the log line.

Active editor
An 'active editor' is a registered (and signed in) person (not known as a bot) who makes 5 or more edits per month in namespace 0.

Very active editor
An 'very active editor' is a registered (and signed in) person (not known as a bot) who makes 100 or more edits per month in namespace 0.

Newbie editor
A 'newbie editor' is a person who has made (fewer than 10? / 10 or less) edits on some Wikimedia wiki in total.
