Graph problems....

Post by Sidius »

Hello
I'm using Cacti version 0.8.7b
And using poller Spine with Poller Interval Every Minute and Cron Interval Every Minute.
Last time i created new graph for my core server and see that something wrong with it (i attach images below). And i created new device and taking graph from it and graph are the same. My previous graph is more smooth than new... why? I check all settings and cannot find a solution...

You are perhaps hitting the rrdtool consolidation, please see http://docs.cacti.net/?q=node/275 and following. For a fair comparison, equal timeframes are required. Then, running at 1 min requires some specific setup of rra's and data sources. That's not exactly an easy task
