Difference between two graphs.

#1 Post by clarityhs » Wed May 15, 2019 1:17 pm

Hey Guys,

We are looking to calculate the difference between two cacti graphs and continuously graph this data. So something opposite to the aggregate function.

Currently have a few interfaces that are now combined under the aggregate function and need to minus this data from another interface. Both are using the 95th.

How can we start doing this ? Also if I am in the wrong forum please point me in the right direction.

It occurs to me that you can use CDEFs or VDEFs to do that, with those you can create personal fomulas using the data sources present in your graphs.

You can create them in Console->Presets then you can use them into your graphs.
