Using Aggregate Graphs on Weathermaps

[cksrealm]

Guys

I am in the process of creating some weathermaps, we have multiple links between routers and I would like to if possible create the link on the weathermap using this aggregate graph, I am not sure if this is possible however.
I am aware that I could do it by displaying 2 links however do to the fact that we have over 400 routers it would make the graph look rather messy.

Anyone able to provide any information on this at all?

Yep, in fact it's in the FAQ, and I wrote an article about it too

Short answer: you can aggregate multiple targets in one link by listing the rrds one after another.

Heh, about two years ago Howie and I had exactly this conversation .

On a similar note Howie, is there any way to set a "Default RRD Directory".

I have a ton of RRD files (over 10k) which all reside in one directory. Currently I use two formats to set the target:

LINK cr1.ex1-cr2.ex1
NODES cr1.ex1 cr2.ex1
SET GID 1
SET RRD some_rrdfile.rrd

LINK cr1.ex1-cr1.ex2
NODES cr1.ex1 cr1.ex2
SET GID 2
TARGET /var/www/cacti/rra/some_rrdfile-2.rrd /var/www/cacti/rra/some_rrdfile-3.rrd

Is there any way to set a default rrd directory in the global options, so if there are no "/"'s in the TARGET it looks in N Directory? That would clean my target lines up and make all my scripts more easy to read (this is clearly not a functionality request)

Thanks for the fantastic tool Howie

You can use {} variables in target lines, so you could do

Yea, that's just as complex (not that it is complex mind you, just a lot of text that 'could' be assumed by a variable at the top).

I was sort of thinking like:

RRADIR /var/cacti/rra/

as a top level config option, then if the TARGET didn't have a '/' it would prepend the RRADIR to it. I admit, I'm not that deep in the php to know if that idea would work .
