Stats Design

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.)

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

• DW::StatData
• DW::StatData::*

Collecting statistics

1. etc/stats-collection.conf should contain something like:

   ## collect and store all stats under the accounts category
   
    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: "*"
