typehash = {}
for d in dmd.Devices.getSubDevices():
    if typehash.has_key(d.getDeviceClassPath()) == False:
        typehash[d.getDeviceClassPath()] = []
    typehash[d.getDeviceClassPath()].append(d.viewName())

for key in typehash:
    print """### %s\n""" % (key)
    for item in typehash[key]:
        print "*   %s\n" % (item)
    print ""

Run it in the zenoss console, or anything with a dmd connection. Tested on 2.5.x, but should be trivial to port forward if it breaks.

(PS: I could probably fix up that last bit to do something with .iteritems() instead…)

And then today I needed that info again. \o/ for IRC logs. To do this, connect to the dmd (on my system, which is installed with the debian package, the command for this is su -c “/usr/local/zenoss/zenoss/bin/zendmd” zenoss. Adjust it for your own system), and then run the following code

foo = dmd.Events.getSubEventClasses()
for i in foo:
    if len(i.transform) != 0: print "%s :: \n%s\n\n" % (i.getOrganizerName(), i.transform)

This will give you human-readable list of all your existing transforms, which makes it easy to find and re-use them.

Edit: this is confirmed working on 3.2.1 (and probably works on the rest of 3.x as well, post in the comments if it doesn’t). Thanks to jmp242 from #zenoss for testing.
