Hi all,
I'm using the following code to make shaded graphs:
"CDEF:shading2=myusers,0.98,*" "AREA:shading2#FF" \
"CDEF:shading10=myusers,0.90,*" "AREA:shading10#FF0F00" \
"CDEF:shading15=myusers,0.85,*" "AREA:shading15#FF1800" \
"CDEF:shading20=myusers,0.80,*" "AREA:shading20#FF2D00" \
"CDEF:sh
Has anyone written any code to do trend analysis and prediction on rrdt?
What I'd like to be able to do is do some sort of prediction based upon a rrd
and predict what it will be at a future point in time based upon the past
trends. I'd also like to be able to predict when a device will reach a

Hi all,
I'm trying to graph how often google crawls some pages on my site.
So far, it can be as frequent as 1 day, other times, it might be weeks or
months.
Does anyone have an idea how I might be able to use rrdtool to grapgh something

It would be nice if someone wrote a set of tools that allowed things like this
to be possible. Removing DS's, adding additional DS, etc. Just an idea for the

If you are using MRTG to collect the data you can use the trend plugin
with routers2.cgi.

Hi,
'rrdtool fetch' would give you values in
timestamp: form.
So write a small script so that, each line obtained
using 'rrdtool fetch' from the original rrd is
inserted into the new rrd using rrdtool update.

Hi everyone,
I have about 100 rrd's that I'd like to modify and add Holt-Winters forecasting
to.
Being that I have a 12 months worth of data in each of them, I'm reluctant to
blow them away and start again.
I'd like to modify the existing databases to include

Has anyone done any forecasting rrdtool to give an indication of future growth?
For example, give the past week or month or year load, use that to calculate
possible future trends? Or even implemented Holt-Winters? If so I'd like to

Hi all,
I've read the few brief pages on the RRDTOOL website about HW-forecasting.
It sounds interesting, but has anyone actually used it?
Has anyone converted existing rrd's to include the HW stuff? If so, how?
cheers

Here are some suggestions;
Depends on how complicated you shell/awk scripts are.
Calling individual shell scripts are slower than having parameters read into a
loop to go thru each server.
i.e.
while read servername
do
[snmp walk $servername]
[update rrd $servername]
[rrd graph $servername
I've not tried this, but I think one way might be to export the data using
rrddump, modify the xml content, then use rrdrestore to reload it.

It looks like your rrd may have no data in it...
You also seem to have an extra character in the DEF command.

Perhaps there was a 'spike' in the data that set the max to a crazy figure. If
you know the maximum possible, set that as a limit in the rrd.
