can i create a graph with data from multiple hosts?

[ashfieldm]

Hi,

I'm trying to create a graph which would display the number clients connected to an access point. I'd like the graph to show this counter for multiple hosts on one graph. That way I'd quickly be able to see which AP's are busiest, etc..

It seems that I can only apply my graphs to particular hosts. Is there a way to apply multiple hosts to a particular graph?

Total newbie here, so sorry if this is simple!

Thanks

Hi

you can do this : when you add a graph, select "None" as host.
You'll then be able a choose data sources from any host.

This answer is not very well thought out. It's just wrong.

Can anybody shed some light on the original question? I've searched through the forum for hours and haven't found a good answer yet in regards to creating a summation graph for multiple hosts.

To be clear, I have multiple hosts that I'm tracking interface stats via SNMP. I can see graphs for each host and if I weren't so lazy, I could get out my abacus and add all of the inbound traffic and then the outbound traffic and then draw myself a graph with crayons and cardstock. However, I have a pretty nifty thing in my racks called a computer and I'd like it to do the work for me.

I know it's possible to see one graph with multiple host's data aggregated within it, I just can't find a howto to tell me howto.

Thank you very much in advance for your help.

The answer works just fine, but the problem I'm running in to is the description of the graph itself. This is what I end up with when I choose "None" and enter the data sources I want aggregated:

|host_description| - Traffic - Aggregate

Can someone explain an easy way to modify the |host_description| field after the graph has been created?

If the Graph was generated from a Graph Template, visit that Template and check the "Use per Graph Value" checkbox for the title. Now, the title of the Graph will be editable
