I assume you mean the right hand side of the graph. If the last known value in your database is at, for instance, 14:54:00 and you create the graph at 14:55:30, there is no traffic *in the RRA* for the interval 14:54:00 to 14:55:30. This is the gap you're seeing. The way to get rid of it? Just graph until 14:54:00, not "now". If your front end does something like "rrdtool graph x.gif DEF:.... " etcetera, change it into: TIMENOW=`date +%s` TIMENOW=$((TIMENOW/120)) TIMENOW=$((TIMENOW*120)) rrdtool graph x.gif --e $TIMENOW DEF:..... The 120 in these calculations is the same as the interval for the smallest RRA. cheers, -- __________________________________________________________________ / [EMAIL PROTECTED] [EMAIL PROTECTED] \ | work private | | My employer is capable of speaking therefore I speak only for myself | +----------------------------------------------------------------------+ | Technical questions sent directly to me will be nuked.
