graph aggregation

[leventkurt]

hi there,

im using cacti for about two years long, two years ago when i first met cacti, one of the biggest problem was to sum 2 or more graphs to receive one.

what i did was to add new CDEFs (like cdef=a,b,+,8,*) and build graph templates like "Summary of 2".

today i need a new sum graph in my new job; i have to sum lot of interfaces, like 11 in 1, 18 in 1. i didn' t want to create these CDEFs and Templates, instead i look into forums and see gandalf's aggregate plugin.

so i installed and have a try. but this is clearly not i wanted. what i want is to have a graph, and only totals under the graph. graph that i attached is actually what i wanted, but this is sooo manual comparing to the one's of gandalf's plugin.

is there any other plugin to sum up graphs? or am i doing something wrong in gandalf's plugin?

The plugin aggregates stuff graphically. You may want to stack the individual graphs. But summing data sources is not (yet) supported. It's the most wanted feature by now.
You may add a new item manually and use the CDEF pseudo variable SIMILAR_DATA_SOURCES_NODUPS or TOTAL_DATA_SOURCES_NODUPS for summation
