We do this, but its SQL Server based.
First, Go into your Servers table and make sure your Location fields are
setup so that they match (typically your regions or pops).
Then create a table like this:
CREATE TABLE dbo.OnlineCount (
Date smalldatetime NOT NULL ,
Location varchar (15) NOT NULL ,
UserCount int NOT NULL
Lastly, using SQL Executing to execute a command like this on what ever
interval you want your granularity:
Insert Into OnlineCount
Select GetDate(), Location, Count(Username)
