Thanks a lot, Sven! Still fairly new to rrdtool and never used the "updatev" option, gonna check it right now.
Do you have any documents handy on how you implement this? if you do, could you point me the link? Regards! Joh I use the aberrant behaviour detection in rrdtool and I find
it quite handy. To detect problems, i use the 'rrdtool updatev' command, which will output FAILURE=1.0 (different syntax), if it detects failures. FAILURE=0.0 if not. In other words, I parse the output of the command, and trigger alerts based on it. You should probably implement a wrapper around the parsing/alarming, so that you won't get flooded with mails/SMS messages every five minutes while a deviation is happening. Sven
