This page can be used as a guide to obtain detailed performance information of your instance.

It is important to know the following :

Users and usage

ユーザー

What is the typical number of concurrent active users i.e. number of concurrent requests being processed?

• users with currently active requests
• users currently using Confluence: eg including reading a page, editing a page, viewing search results.
• users with sessions held in application server memory.
• users logged in active users (Note that Confluence uses "Remember Me" Session cookies and in my experience of Confluence, users never explicitly log out).
• define user types (viewer, editor, etc)

– light viewer
– rss reader
– searcher
– infrequent editor
– frequent editor
– administrator
– commenter

用途

What is the average number of pages created per day, and similar usage stats (AWStat reports are a good starting place when User Access Logging is enabled)
To help interpret the raw access data, consider these important URL patterns:

Usage statistics gather from database

Note: specify the date range

1 日あたりの作成されたコンテンツ

select contenttype, min(number_of_changes), max(number_of_changes), avg(number_of_changes)
from (
    select contenttype, date_trunc('day', creationdate) , count(*) as number_of_changes 
    from content 
    where content.creationdate > date '2007-01-01' and version = 1
    group by contenttype, date_trunc('day', creationdate)        
     ) as dates
group by contenttype
