Hi guys..

Ive been using routers2cgi for many years now and all has been quite happy..

Ive got a situation at teh moment though where i need to add a number graphs together to display one 'total' graph..

a bit like using the 'incoming' and 'outgoing' graphs but instead of showing them individually per device, to total them together based on the category they're in.. and display both total incoming and outgoing on one graph..

for example.. i have 20 interfaces in 1 x .cfg file (so i dont have to include nultiple cfgs).. and i want to 'add' them all up to create 1 x graph with total incoming and outgoing on a graph..

does that make sense..

possible ?

Yes, possible. You need to make a userdefined graph.

You can make the sub-graphs either as normal lines (like in the incoming graph) or as stacked areas. Then, you can optionally add a total line, and/or an Average line.

For an example, see the demo routers2 system on this website, and look at the CPU graph for the linux server. This is 3 stacked sub-graphs. You can also see the .cfg file used to generate it here.


Read the doc/HOWTO for details, but the directive you need is

routers.cgi*Graph[subtarget]: summaryname withtotal

for each subtarget, and then

routers.cgi*GraphStyle[summaryname]: stack

if you want it stacked. Many other options are available as well. If you don't have noo or noi set, then it totals both incoming and outgoing. You may also want nodetails set, if you are only interest in the final total and not the legends for the sub-lines. If you have v2.17b2 or later, you can use the 'nolines' option to hide the sub-lines entirely.
