Graphing Max value

otisbrown · Post by **otisbrown** » Fri Apr 11, 2008 1:18 pm

I created a graph for a netscreen fw that graphs the current sessions. I am able to graph the average, but I also want to draw a line on the graph that represents the maximum. The gprint displays the correct value, but when I create the line it represents the current number of sessions. Can Cacti draw graphs based on the maximum value?

TIA

Sure. Please select the Consolidation Function "MAXIMUM" when defining the Graph Item.

Thanks Gandalf,

That is what I did, but the Line is not drawing the Maximum. It is actually drawing the current. However, my gprint is specifying the Maximum.

Please post debug screenshot from Graph Management, then

Here you go.

RRDTool Command:

RRDTool Says:

OK

The AREA refers to AVERAGE, the LINE1 to MAX, fine.
Diffrences will be shown only when leavin the first consolidation level (usually seen on the weekly graph, NOT on the daily one)

Thanks Gandalf,

I have always had the graph set up that way(with the line using max), but no matter what time frame I look at the line never shows the maximum value, while the Gprint does. Any ideas?

Please post a screenshot of a graph spanning, let's say, a month

I'm having the exact same issue with one of my traffic graphs. Was this ever resolved?

Regards,
