hi,
first the easy question. How can I make ala mrtg CURRENT, MAX and AVERAGE
legend when generating
with rrdgraph? This should be with CDEF, isnt it ?
Can u give me example...
Now the second one.. I have thousand of .rrd's under thousand of dirs.. Now
what I want to do is
walk over all these rrd's and based on some condition group them (fetch the
values) and then
combine all these in one stacked graphic with one area for every group..
This is imposible with rrdtool alone, isnt it ? I need to have some script
which will walk and extract the data..
The other thing is that I dont want this to happen every 5 min but just on my
request... so fetching will be
a little bit harder...
Could u advise me how to do this, some exaples (even in pseudo code)...
I will be using perl..
On the other hand it will be probably better to not build graphic but another
.rrd instead, but then I have to
do it every 5 min.. Is there a way to make non-5min fetch-make-rrd easier..
('cause in this case I will have to look from what time i dont have data in my
combined .rrd and start fetching
from other .rds from that time onward ..etc..etc...)
tia
