[mrtg] Re: Plot more than 2 variables

[Steven Williams]

I've been doing this for a while with a custom CGI script which I've
attached an example. This runs on Win2000 server.

I use a normal MRTG config which generates numerous .rrd files, and I simply
combine the data from the numerous .rrd files with this .cgi script. I've
had no problems graphing up to 10 variables this way. It's a little bit of
work to setup, but once its done it works well, and you don't need to know
Perl which is a bonus for me.

Results look like the gif file I attached.

Give me a yell if you have any problems

In fact, it would produce three: 1, 2 and Combined.
Routers2.cgi allows this.

In fact, you can fine tune it further to remove graphs 1 & 2 using the
routers.cgi*InMenu and routers.cgi*InSummary options

The section in the documentation doesn't explain routers.cgi*Graph
particularly clearly, just try it and see what you get. Especially useful
is the Total option instead of doing OID maths.


-----------------------------------

Won't that produce 2 separate graphs? I believe he meant having more than
two lines on one graph.
I have been looking for a way to do this also.
Thanks

Target[1]: 1:public at ipaddress
