This usually means that you've got a step interval of 5 minutes in your RRD file (which I believe is the default). You may be pumping in data every 1 minute, but RRD is only going to put in a new value every five minutes (an interpolated value from those 1 minute runs). The solution to this is to either update your RRD to store values on 1 minute steps (which will make a very large RRD file) or change your graphing end time to be ( current time - ( current time % 5 ) ). That's how RRD stores it's data, so your ending time will always be on the last RRD data step. * Philip Molter * DataFoundry.net * http://www.datafoundry.net/ * [EMAIL PROTECTED] -- Unsubscribe mailto:[EMAIL PROTECTED] Help mailto:[EMAIL PROTECTED] Archive http://www.ee.ethz.ch/~slist/rrd-users WebAdmin http://www.ee.ethz.ch/~slist/lsg2.cgi
