graphing multiple oid's and combinging from several machines

Maybe I did this differently than most do. I copied the "SNMP - Generic OID Template - Data Template" for each oid. Then I created a graph template that graphs the 3 items. Then I went to "new graphs" selected 1 server, went to "create" drop down box, selected the "graph template" that I just created, and then hit create. I repeated this process for all 10 servers. So now I have 10 graphs graphing 3 data points.
If this is correct, then I dont follow how to go about it the way you are telling me. If I create another graph template, how can I apply that to all 10 servers?

Good, up to now.

You won't. As this is kind of an "Overview Graph", including data from multiple servers, you won't associate this one to a single host.
To create a Graph using the new Graph Overview Template, goto Graph Management and Add. Select the new Graph Template and Create.

I dont understand how you are telling cacti to read the rrd's into this template.

The rrd's are linked to each data source. So by giving the data sources, you'll get the DEF statements

Ok, steps I did:
1. Graph management ---> add
2. Under graph item templates, selected each oid and under cdef, selected "total all data sources".
3. Did that for each oid I wanted to graph.

Now the question is, how do I graph this template? From every other template I've used, I applied the template to a specific server.

In fact, you've now created a Graph, not a Graph Template. So nothing is left to do, except for placing this Graph on some Graph Tree, if you like

Ok, I took your advice, and went to graph management, new, added all the sources and stacked them to produce a nice graph. Now I want to do a "total", however I get segfault after I add it. This is how I added:
Under graph items>>>>add
Host = any
Data Template = any
Data Source = None
Color = black
Graph item type = line 1
Consolidation function = Total all data sources
Value = blank
Gprint type = Normal
Insert hard return = blank

RRDTool Says:

Segmentation fault (core dumped)

Any ideas why the "total" is causing seg fault? As soon as i delete that total item, graph is perfect.

Anyone have an idea on why this is causing segfault? Should I be doing something differently to get the total?

The cdefbe DEF is wrong. Please check your graph items again. BTB, rrdtool shouldn't segfault. Please post this error to the rrdtool mailing list (see: http://www.rrdtool.org)

I checked the data sources and your instructions, still a bit confused. I added all the data sources, and that graphs fine. I tried adding "legend" and total all data sources, still get seg fault. For the legend, if I select a data source, it doesnt seg fault anymore, but also doesnt create accurate total data.

In graph management, I select the product view graph, under graph items, I click add, set host as any, set data template as any, data source as none, color is none, graph item = legend, cdef function = total all data sources, gprint type = exact numbers, and then hit create. Then seg fault happens. I have tried setting the data template to the template I used for each host, still no go. Are the steps I'm taking correct?

Please post a screenshot of this before createing

Ok, here is screenshot before I hit create.

I only just noticed, that the above is not correct. The first data source should be an AREA, the following one should be STACKS

I'm not sure why it doesnt say area, however it is set to area, and the others are set to stack. For whatever reason, the debug output is not showing it.

So please try re-creating this using the topic linked above (this is a more detailed instruction compared to mine)
