Re: Setup for a 5 minute average Bandwidth graphing

Hi William,
If I am not mistaken, it's an rrdtool issue, meaning that rrdtool takes the
RRA most appropriate to the timescale that you try to graph. If your rrd
file contains both the monthly/2hours avg and monthly/5min average, rrdtool
will take the monthly/2hrs because it generates the good number of points
for your graph.
Have you tried to suppress the normal monthly (2hrs avg) from your template
?
In the end, depending on the size of your graph, and thus the level of
detail, I am not sure that doing what you do will be relevant. You may have
to few pixels to graph all the points of the RRA and then the graph will
have a weird graphical effect.
Please correct me if I am mitaken :)
Vincent.

Has anyone had any luck setting up Cacti to show a 5 minute average not
just on a daily basis?
I am running Cacti 0.8.5 Ve
By default Cacti will graph bandwidth based on the RRA as follows:
Consolidation Functions = Average and Max for all
steps rows timespan
X-Files Factor
Daily (5 Minute Average) 1 600 86400
0.5
Weekly (30 Minute Average) 6 700 604800
0.5
Monthly (2 Hour Average) 24 775 2678400
0.5
Yearly (1 Day Average) 288 797 33053184
0.5
I added a new RRA as:
Monthly2(5 Minute Average) 1 8928 2678400
0.5
I then select "Monthly2 (5 Minute Average)" under Data Templates in
Interface - Traffic - in and - out
When I compare the "Monthly2 (5 Minute Average)" graph against the
"Monthly (2 Hour Average)" graph they grow the same and the max and current
Mb are the same?
What am I doing wrong? I have looked over the docs and as far as I can
tell this should work? I think my math on the RRA's Im looking for are:
Daily (5 Minute Average) 1 600 86400 0.5 "Stays the same"
Weekly (5 Minute Average) 1 2016 604800 0.5
Monthly (5 Minute Average)1 8928 2678400 0.5
Yearly (5 Minute Average) 1 105120 33053184 0.5
Thanks for your help
Bill Richardson
