Hello Toasters.
Some may have noticed my search for a simplified monitoring tool awhile back. Alas, I never found such a tool. So I finally broke down and just wrote my own. So far I've only got about 2 hours worth of developement into it, but it's mostly what I want already. I thought I'd see if anyone else was interested in it or could propose suggestions for it.
It's called "Toasterview" (I wanted to call it ToasterVision, but that seemed to silly) and you can see an example output page here:

Some notes about this sample page. Firstly, the Head image you see at top does, you'll notice, match the model of the filer so you can "see" what the head looks like reguarless of which model it is; right now F7x0, F8x0, F940 and F9x60 are handled. The logo image in the top right is, of course, intended to be changed to your company logo so that your boss is impressed. The global status box changes from green to red based on status. But, the most interesting and important part for me is the DF output. Using the DF SNMP table I can parse it up and display how I like, so I display volumes in nice round numbers (using 1024 insteal of 1000) for easy reading and a little bar graph that lets you see volume usage in an instant. Also, the last line of the DF table is a "Total" line. This simply adds up the data from all the non-snapshot volumes and displays this information like anything else. It's kinda nifty to be able to take 1 look and confidently say "We're using X% of the filers capacity" rather than just approximating off the top of your head.
Anyway, this is the kind of tool I want. I need to clean up the source so it's pretty and then I'll GPL it. Anyone interested or what to make suggestions?
I should note that I'm actually supplimenting this page you see with extra data at the bottom as supplied by RRD graphs and such... however that stuff is all system specific whereas my current script as demostrated works on any NetApp Filer (I guess NetCache too). The colors and stuff need tweeking, but you get the general idea.
