Add up data from multiple hosts

[getUP]

Is it possible to add up data from multiple hosts into one graph for instance?
Any other way would be fine as well.

We'd like to know how much mail/spam is handled by all our mailservers all together.

Yes, it is possible. Go to configuration of graphs, create a new one, add as many metrics as you want.

[getUP]

I don't think that covers it. It shows not exactly what I mean. But maybe I'm missing something.

With adding up, I mean having one final graph without multiple metrics. So there is only one left, containing all data added up. This way, we can see how many e-mail our mail servers are handling instead of having to do it manually.

Perhaps a stacked graph would hlpe. Not quite what you need though.

I'd suggest investigating the grpsum item type? It will create an aggregate of items.

We also use stacked graphs at our place for mail servers so that we can see the total but also compare which server has the largest mail queue.

That seems to be it noxis, great! Thanks!
