Custom DataSource's from Vendor MIB's

Yes, you can create custom Datasources from these pretty easily. You simply need to identify what data from the MIB you want to poll. The answer to this question usually comes in the form of, "I want to poll all the data that's in the mib table at 1.3.6.1.4.1.a.b.c.d.e.f.g."  I've been meaning to write a blog going through this process, so if you don't mind working through it here in this public forum, we can work through it. The first thing to do is to look at the MIBs themselves. Can you link to the MIBs here along with any ideas you've got so far about what data in the MIB you want to poll? Usually a MIB browser like this one can help you understand what data is in the mib and what form it takes. That's where I'd start.
