Graph based on script result

Anyone ever done something like this?

Lets say I want to graph the number of connections on a LNS machine over time. I have a script that will SSH into the software, execute the command and parse the results to get the total number of connected sessions. This is cron'd every 10 minutes. This is currently graphed using Cricket, as the cron job writes connections to a .csv file, and the cricket poller yanks those stats every 10 minutes from the .csv and graphs the usage.

Unfortunately this info is NOT available via SNMP. I'm currently gathering BW details, and response time for this node with Solarwinds.

Would there be a feasable way to include this information somehow when viewing the Node Details of that particular node? I assume to get this to work I would likely need to modify the script to store the results directly into the NetPerfMon database? I've also done some searches in the forums and am coming up blank. This seems like it might have occured to someone else before....as many interesting variables aren't always available via SNMP, which would be very cool to have integrate into the main webpage.

Euphorik,

If you could get the resulting graph into a webpage format, then you could add a 'Custom HTML' resource to your Node View that would reference the page with the graph that you want. I am not familiar with Cricket so I do not know all of its capabilities for output.

The idea is I want to move away from Cricket (which is a derivitive of RRD Tool / MRTG) if I can, and consolidate onto our Orion platform. I figured I'd have to schedule a job to remote in and grab my stats, but I'm not sure if anyone has thought of a method of storage, or what I can do with the results once I obtain them via expect.

I suppose I could leave Cricket running, and graphing, then pull that particular graph into the Node Details page in Orion. Was kind of hoping for a way to shut that server off though :-p

Euphorik,

You are positive there is not an OID that could be used to collect this information via SNMP? If you can find one then it would be a simple matter of setting up a Custome Poller to collect it into the Orion DB.

Yep. The app in question is a sourceforge build called L2TPNS used for LNS termination. Works great for our application, but obviously there isn't likely to be a MIB for it which means we need to write a script to go into the app and pull our stats out manually.

Would be ideal if the "custom poller" had an option to be a script, and would simply run every 10min and report the result given to it by the script!

Hi Euphorik

How did you get cricket to graph CSV files? I need ideas on how to get cricket to graph CSV files. I already have cricket up and running and unfortunately the device I want to graph doesn't support snmp statistics collection.

I can graph the same device using MRTG. Give me an insight on how you did.

Thanks
