Jangle provides a simple graphical snmp browser.
It is based on (as in a simple cut-and-paste job) some code from JKstat and leverages Jonathan Sevy's Java SNMP Package for basic SNMP support and Mibble for MIB parsing, and JFreeChart for the graphical charts.
(Note: I'm using Mibble 2.3, which has the GPL Library Exception. It's good enough, and allows me to continue on with this project without licensing headaches. I haven't gone far enough to be sure that I'm going to finish this project, or whether I'll use the above components, so picking a version that forced me into relicensing didn't seem convincing at this stage.)
The idea was to produce graphical charts just like I can in JKstat. I had a look around for existing utilities to do this, but none seemed complete.
Hence what I've produced so far. It started out as a simple exploratory tool: what's possible in this space? It's evolved into something that's starting to be moderately useful, if a little unpolished.
Just a simple screenshot:
The About tab gives you details of the relevant MIB entry. Siblings are different instances of the same thing; cousins are different properties of the same instance.
