Now looking at it I won't need to change much apart from the regex that's extracts the data which is currently:
Online now: 59 (members: 9, guests: 50)
The second thing I'm trying to do with munin is then track how many posts and threads and members I've got on my site as it grows. (I know xenforo has this build in, but I want to be able to see it as part of the munin charts with the other information without having to log into xenforo.)
<dl class="discussionCount"><dt>Discussions:</dt> <dd>7,050</dd></dl> <dl class="messageCount"><dt>Messages:</dt> <dd>125,986</dd></dl> <dl class="memberCount"><dt>Members:</dt> <dd>1,048</dd></dl>
Thirdly is there any way to simply output the above information so that I don't have to have it load the homepage every time. I'm thinking maybe a Page thats not displayed on the node tree with just that into on.
