Then you have to tell RRDtool to store at ***exactly*** the right time. > As you can see there is a slight difference between what Cacti reports > and what rrdtool stores/graphs (in fact, each value differs towards its > preceding value).

Might any other averaging > mechanism fool me here? COUNTER -> rate = delta(counter)/delta(time) ABSOLUTE -> rate = (value)/delta(time) GAUGE -> rate = value. Then: rate -> normalization -> RRA. *If cacti is using something similar to "rrdtool update N:12345" then what is "N"? N is approximately "09/22/2003 9:40 AM". N is not exactly "09/22/2003 9:40 AM" HTH Alex -- 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
