Has anyone had any luck using qmail with mrtg? I am using the qmailmrtg7 executable from here: http://www.inter7.com/index.php?page=qmailmrtg7 The script works fine for other graphs, ie cpu/memory usage, but for every qmail graph I can't seem to get anything to display (except for the queue size as that just looks at the directory). In the requirments for qmailmrtg7 it says it needs tcpserver & multilog. So I assume that I need to modify qmail to use multilog? Is this going to cause any problems with Plesk? And if not when a new upgrade comes out is it going to erase the changes?
