This is a a loosely organized collection of notes and links for the Stats feature design. (Note: this is for the new stats system only - there's an existing legacy system too.)

Bug 124

Stats project team (we're recruiting)

Table definitions

CREATE TABLE statkeylist (
    statkeyid INT UNSIGNED NOT NULL AUTO_INCREMENT, 
    name VARCHAR(255) DEFAULT NULL, 
 
    PRIMARY KEY (statkeyid), 
    UNIQUE KEY (name) 
)
 
CREATE TABLE site_stats ( 
    category_id INT UNSIGNED NOT NULL, 
    key_id INT UNSIGNED NOT NULL, 
    insert_time INT UNSIGNED NOT NULL, 
    VALUE INT UNSIGNED NOT NULL, 
 
    -- FIXME: This is good for retrieving data for a single category+key, but 
    -- maybe not as good if we want all keys for the category, with a limit on 
    -- time (ie, last 5 entries, or last 2 weeks). Do we need an extra index? 
    INDEX (category_id, key_id, insert_time) 
)

Storing statistics

DW::StatStore

Statistics items

Collecting statistics

  1. etc/stats-collection.conf should contain something like:
    ## collect and store all stats under the accounts category
    
    1. hangs if you don't enclose the asterisk in quotes
  2. accounts: "*"
    1. collect and store only these stats under the accounts category
  3. accounts: [ identity, personal, redirect ]

accounts: "*" active: "*"

paid: "*"
  1. bin/worker/stats-collection is the utility that handles stats collection. Run at least once per 24 hours, either from your crontab or by listing it in etc/workers.conf.
  2. (only needed if you chose to use etc/workers.conf): add a line to the "all" section reading:
      stats-collection: 1
    (note: this is for development only, as it assumes you only have one server - in production environments, you will usually list it in the section for a specific server)

Displaying statistics

(note: as of March 28 there is an uncommitted patch on bug 124 [[Routing_and_Template_Toolkit|TTizing] the stats display to DW::Controller::SiteStats, views/admin/stats.tt, view/site/stats.tt)
