If all you are interested in is having a summary graph of the Incoming traffic,
and another summary graph of the Outgoing traffic, then Routers2 does this
automatically. You can put 'showtotal=yes' in your routers2.conf and the
Incoming and Outgoing graphs will be generated with additional Total traffic
lines.
However if you want to do this by a subset of ports, or on a single graph, then
you'll need to do more work.
What you will need to do is to define a UserDefined summary graph over the
ports that you are interested in. This summary graph can optionally include
the separate lines for the ports, optionally stacked, with a Total line. I
would suggest you suppress display of the numerical per-port data and per-port
lines, and only include the total numbers and total lines, else it would be
confusing - though you could use stack-mirror mode and include the per-port
data.
To generate this automatically from cfgmaker, you'll need to use interface
templates and host templates. The Host template should define the display
parameters for the summary graph; the interface tmeplate should add the
interface to the summary graph (if it meets the criteria you specify). This
will require a bit of Perl coding knowledge.
Here is an EXAMPLE that needs a bit of work to complete.
Host template:
$target_lines .= <<ECHO;
routers.cgi*ShortDesc[mygraph]:Total
routers.cgi*Title[mygraph]:Total traffic
routers.cgi*Options[mygraph]:total nolines nodetails
#routers.cgi*GraphStyle[mygraph]:stackmirror
#routers.cgi*Options[mygraph]:total active
ECHO
And an interface template:
$target_lines = $default_target_lines;
if( insert your condition here ) {
$target_lines .= "routers.cgi*Graph[$target_name]: mygraph total nolines
nodetails\n";
}
With a little work, this should achieve what you want automatically.
Alternatively, you can manually set up a set.
Other useful options for the routers.cgi*Graph definition are 'active' (which
will suppress components which are not active - remove the nolines and/or
nodetails options if you use this), and if you remove either nolines or
nodetails, you may want to use routers.cgi*GrpahStyle[mygraph]:stackmirror in
the host template to get a stacked/mirror graph.
There's a lot more information on this in the documentation, in the book
http://steveshipway.org/book/ or in the forum http://www.steveshipway.org/forum
and there are some demo configurations showing stacked userdefined graphs in
the demo site http://www.steveshipway.org/cgi-bin/routers2.pl

Subject: Aggregate switch mrtg
I have installed and run mrtg on a 52 port switch which is running. Now i want
to generate the aggregate for ports in use. How do I get the file to run to
generate this.
