You right, I did not specify that part. The place to change colons and 
equal signs is the status (or data) message which is sent to Xymon. I've 
seen a few times that a line containing a colon resulted in an unexpected 
RRD file to be created.

The RRD collector in Xymon searches for lines, which contain a colon or an 
equal-sign and satisfy some other criteria as well. By replacing the colon 
or equal-sign in those lines which are not meant to contain data for an 
RRD, you're certain that those lines will not result in funny RRDs.
