Hello Vernon
I've written a script that gathers data from the squidclient
util (just called client in the earlier versions).
I've just started collecting data so I don't have error status's set up
yet ...
The squidclient util will give can give you ridiculous amounts of data
on squid memory usage, disk IO, 5min and 60min averages etc.
Squidclient mgr:menu will tell you what you can get.
You should be able to change the client script to grab what ever data
you want ...

That gives me pretty graphs about traffic and number of clients.
Hope that helps.

Subject: [hobbit] Squid & Dansguardian
Hi all
I detest reinventing wheels, so let's first check if they exist.
Has anybody got anything to monitor Squid and/or Dansguardian?
Regards
Vernon
