What you are saying is like this in pseudo code: > while forever > do > run_rrdtool > sleep 60 > done The execution time of this loop is more than 60 seconds. Say it takes 0.1 seconds to 'run_rrdtool'. If you require the updates to be no further apart than 60 seconds, and if you update every 60.1 seconds, each update will arrive too late. I'm not saying this has to be the cause of your problem. I do say something like this is the most likely cause. Try changing that 'N' into a real timestamp and then log every update command so you can do some analysis. -- Alex van den Bogaerdt http://www.vandenbogaerdt.nl/rrdtool/ -- Unsubscribe mailto:[EMAIL PROTECTED] Help mailto:[EMAIL PROTECTED] Archive http://lists.ee.ethz.ch/rrd-users WebAdmin http://lists.ee.ethz.ch/lsg2.cgi
