Multiple output fields, one graph

Post by Norm »

I'm beginning to configure Cacti, and I'm sure I'm not the only one who's very impressed, but a bit confused once I leave the comfort of the built-in templates...

Here's my question: I've got a script that spits out the number of users in each of our VLANs. I believe I've correctly turned this into a data input method with seven output variables, one per VLAN. I'm passing the hostname to the script as a parameter, which is handy.

I think I've got a data source configured. I tied my script to a given device.

Now when I create a graph, I'm was hoping to see my seven output variables as data sources to create lines; however, it's not breaking them out individually.

Am I going about this the wrong way? What's the best way to take multiple outputs from a script and graph them together on the same graph?

Thanks for any advice,

Norman

Can you post some screen shots of script output, Data Input method and your Data Source Template?

Thanks for the reply. Here's my script output...

Code: Select all

100:2005
128:34
144:86
160:26
176:24
200:938
520:135
I've attached pictures of my data input method, my data source, and my graph items screens.

Ideally, I'd like to automatically graph whatever rows the script outputs. I'd settle for having to manually configure the rows for now.

Thanks again for any advice,

Norman

I would make this a data query because you never know what the vlan numbering will be. The beauty of a data query is that the values can change from switch to switch and your query works just as well on each.

Of course it would have to be a custom script based data query such as ss_host_disk.php.

For every output field you have, you need a Data Source Item in your Data source. Then you can select the appropriate "Output Field" at the bottom of the Data Source Item section.

Now I see where you configure the output field per data source, so it looks like I've got things straightened out. Thanks.

It appears; however, that my script is being run once per data source. Is there a way to configure it to run once, and the output be parsed for each data source?

Thanks,

Norman
