Aggregate with 95th summed traffic individually

[skhosla]

Hi,

I am running into a bit of a brick wall here and was hoping someone can help.

I am using the aggregate plugin to combine multiple ports from multiple routers in a single graph.

Aggregate is working fine. I have set it up so that all of my inbound traffic is on the positive axis, and the outbound is on the negative axis.

What I want to do is find the hrule function that will add up all of the inbound traffic, then calculate the 95th against the summed total and present that so I can graph it. I then want an hrule function that will add up all of the outbound traffic then calculate 95th against that summed total and present it to me so I can graph it on the negative axis.

Having looked at the variable definitions for nth percentile here: http://docs.cacti.net/manual:087:6_refe ... #variables I can't seem to find anything that works like that for an aggregated graph.

I also can't seem to get the hrule to print on the negative axis. I have tried a CDEF function to make it negative, and I have also tried putting a - in front of the variable with no success.

Can someone point me in the right direction?

Thanks
