Create a simple SNMP Classifier. The patterns edition
Hot on the heels of the simple SNMP classifier video I did '8' years ago
(don't hate, sometimes sequels take a while..heh). I just put together building another simple SNMP classifier video this time using patterns.
In this episode, I not only set up the initial classification using the same process as before but also extend the discovery loading custom (private) MIBs when discovering a Riverbed WAN Accelerator, wrapping all the work in a pattern.
First and foremost, proper credit goes to @ryan.zulli as the genesis of the original probe and sensor setup that many of us use today in discovering these devices and @patrick.decarlo whos (pattern-based) update set I used as a guide in building this video. They've done the good work, I just get to do the video and I learned a lot through the process. And having a (developer) Manager like @Tamir Livneh to lean on for help didn't hurt either.
Expect to go through some trial and error, digging through logs and relying on the docs site and most importantly USE existing patterns as your guide. If you get stuck, look to a pattern that works! Meaning, as I've always done when building my own probes and sensors there was always one OOB that did something similar that I wanted to accomplish in extending discovery. Do the same here. I used the OOB router pattern for a lot of guidance in understanding where the steps needed to take place in the work here to make it my own.
As it was before, full disclosure I am not video expert and apologize in advance for the quality and novice 'editing' but hey, I'm just a discovery guy trying to make his way and help his friends out there use new features that are available to us in the tool. This is basic, lots of ways to make it more elegant but it 'works' and sometimes that's all we need...
Enjoy...

Here again, is the link to an actual "professionally built" update set to discover the same type of riverbed devices. @Patrick Decarlo is the author and does a lot of extra steps and checks that I cut out to save time on the video but its the kind of good work we all love to share in, thank you Patrick! One difference is he took the script include route to match Mfg/Mod, I used an existing pre post processing script. Both ways work, can't go wrong..
