Monthly wikistats page view trend reports, indirectly based on squid logs

 * Platform: wikistats server stat1002
 * Update frequency: daily
 * Input: hourly per-wiki page view totals (files named projectcounts-yyyymmdd-hhnnss) ... produced by webstatscollector downloadable from dump server
 * Output:
 * csv file for monthly Report Card
 * daily updated monthly page view stats. These reports are available in 4 variations: for desktop and mobile traffic, normalized (all months recalculated to 30 days) or original. There are reports for every project and a report for all project combined. See sitemap.

Monthly wikistats traffic reports (geo & traffic type), based on un|sampled squid logs
Monthly (manual run) github, dev/beta on squid1002:/home/ezachte/wikistats/squids stat1002:/a/squid/archive/sampled
 * Update frequency:
 * Scripts location
 * Input:

SquidCountArchive.pl
Collects a large variety of data from a/squids/archive/sampled in two passes,
 * updates a few monthly files (in folder /a/wikistats_git/squids/csv/yyyy-mm), and
 * creates a large set of daily csv files in folder (../yyyy-mm/yyyy-mm-dd), subfolders ../private and ../public.

Modules

 * EzLib.pm (now at EZ ~/lib)
 * ../SquidCountArchiveProcessLogRecord.pm
 * ../SquidCountArchiveReadInput.pm
 * ../SquidCountArchiveWriteOutput.pm

Phases

 * Pass/Phase 1: collect frequencies for all ip addresses, needed in phase 2 to filter addresses which are most likely from bots (freq > 1 in sampled squid log stands for 1000 real views/edits, esp. for edits this most likely means a bot (few false positive are accepted)
 * Pass/Phase 2: collect all other counts

Arguments

 * -t for test mode (run counts for short timespan)
 * -d date range, can be absolute or relative, specify one value for a single day, two values for a range of days
 * -d yyyy/mm/dd[-yyyy/mm/dd] (slashes are optional). This is best for generating counts for a specific day or period.
 * -d -m[-n] where m and n are number of days before today. This is best for daily cron scheduling (e.g. -d 1-7 => run for last 7 days before today, skip days for which output already exists).
 * -f [1|2|12|21], for force rerun phase 1 and/or 2, even when that phase completed successfully earlier
 * phase 1: check for existence SquidDataIpFrequencies.csv.bz2 in ../yyyy-mm/yyyy-mm-dd
 * phase 2: check for existence #Ready in ../yyyy-mm/yyyy-mm-dd

Input

 * 1:1000 sampled squid log files from stat1002:/srv/squid/archive/sampled


 * Format
 * 1) see also wikitech
 * 2) 1. Hostname
 * 3) 2. Sequence number
 * 4) 3. Current time in ISO 8601 format (oplus milliseconds), according ot the squid server's clock
 * 5) 4. Request time in ms
 * 6) 5. Client IP
 * 7) 6. Squid request status, HTTP status code
 * 8) 7. Reply size including HTTP headers
 * 9) 8. Request method (GET/POST etc)
 * 10) 9. URL
 * 11) 10. Squid hierarchy status, peer IP
 * 12) 11. MIME content type
 * 13) 12. Referer header
 * 14) 13. X-Forwarded-For header
 * 15) 14 User-Agent header

On file read country codes are added from local copy of MaxMinds free GeoLite Country service as follows: open IN, "-|", "gzip -dc $file_in | /usr/local/bin/geoiplogtag 5" ; (author geoiplogtag Mark Bergsma), 5 means: 5th field contains ip address

Output

 * Most files are written to sub folder ../yyyy-mm/yyyy-mm-dd
 * SquidDataLogfileHeadTail.csv and SquidDataSequenceNumbersAllSquids.csv are reused between runs and updated in sub folder ../yyyy-mm


 * Notes
 * Files marked as private file can contain data which are covered by the Wikimedia Privacy Policy, such as ip addresses and/or referers. These files should never be published! Also these should be deleted after the maximum retention period, set by our privacy policy.
 * Count is number of occurences in one day sampled log, for actual traffic counts scale by factor 1000
 * Country codes are as used by MaxMinds free GeoLite Country service
 * There are several reasons why a requester is classified as bot
 * agent string contains url, which by convention should only occur for crawlers (exception: Embedded Web Browser from: http://bsalsa.com/)
 * name contains bot/crawler/parser/spider
 * for edits only: ip address occurs more than once in sampled log on one day (few false positives accepted)


 * # Ready
 * This file signals successful completion of script's phase 2: collecting all counts except ip addresses.
 * On rerun phase 2 will not be redone when this file exists, except when argument -f 2 (force) is specified.

 * Views:
 * starting in July 2009 for page views
 * input in stat1002:/wikistats_git/squids/csv


 * Edits:
 * starting in November 2011 for page edits
 * input in stat1002:/wikistats_git/squids/csv_edits

 * SquidDataCountries2.csv

Input
Csv files generated by WikiCountArchive.pl.

Output
Once a month generates a lot of reports from the csv files generated by SquidCountArchive.pl. Page view reports are based on a 1:1000 sampled server log (squids) ⇒ all counts x 1000. Page edit reports are identical to page view reports, but based on 1:1 unsampled squid log!

Reports come in two sets
 * Breakdown of traffic by one aspect, see this portal section.
 * How many files are requested each day? Breakdown by file type and target (sub)project
 * Where do those requests originate? Breakdown by file category and origin
 * Where do those request land? Breakdown by file category and destination wiki
 * Which HTTP requests are issued? Breakdown by type and results
 * Which scripts are invoked? Breakdown by type (css, javascript, php), name and parameters
 * Which skin files are downloaded and how often?
 * Which crawlers access our servers? Breakdown by host, file types requested, agent string
 * Which operating systems do our clients use? Breakdown by platform, mobile or not, release
 * Which browsers are how popular? Breakdown by brand, revision level, mobile or not
 * Breakdown of all traffic that Google send us. Directly (crawlers) and indirectly (search results)
 * Breakdown of Wikipedia views by geo info, see this sitemap.
 * Page views by country (and larger regions)
 * Breakdown of page views by country by visited language
 * Breakdown of page views by language by visiting country
 * Quarterly trends in breakdown of views by country by visited language
 * Breakdown of Wikipedia edits by geo info, see this sitemap.

SquidLoadScan.pl
Read all files on squid log aggregator with hourly counts for
 * number of events received per squid
 * average gap in sequence numbers (this should be 1000 ideally on a 1:1000 sampled log)

Write several aggregations of these data: This leads to the folowing report: udp2log message loss, and traffic volume, based on 1:1000 sampled squid logs
 * Hourly average delta sequence numbers per squid (should be 1000 in 1:1000 sampled data set, if no UDP loss occurred)
 * Monthly averages of events per squid per hour
 * Monthly metric per squid set (set defined by location and server role)
