Hello,
I work with Tom Georgoulias over at McClatchy Interactive, he suggested that I share a python Xen VM Monitoring script I wrote for our systems. I've uploaded it to: http://eiknet.com/mi-vt.py.bz2
This script is handy in that it sends information from the Dom0 on behalf of the DomUs. This way VM data shows up in hobbit with the rest of the DomU host information, giving you the following information updated correctly even if you migrate/move the DomU to another Dom0:
Virtual Machine Status
State: Blocked HostServerMemUsed: 49.99% MaxMemSet: 2048 MB CurMemSet: 2047 MB VCPUs: 2 Dom0: hostname
It also reports information about all DomUs on behalf of the Dom0:
Virtual Machine Status
Host Server Specs MB Memory: 8191 Num CPUs: 2 Num Cores: 4 CPU MHz: 2666
hostname01 State: Blocked HostServerMemUsed: 12.49% MaxMemSet: 1024 MB CurMemSet: 1023 MB VCPUs: 2
hostname02 State: Blocked HostServerMemUsed: 24.99% MaxMemSet: 2048 MB CurMemSet: 2047 MB VCPUs: 2
hostname03 State: Blocked HostServerMemUsed: 24.99% MaxMemSet: 2048 MB CurMemSet: 2047 MB VCPUs: 2
hostname04 State: Blocked HostServerMemUsed: 6.24% MaxMemSet: 512 MB CurMemSet: 511 MB VCPUs: 2
The scripts turns yellow on the system being paused, and red on the system being crashed, dying or in shutdown states. You only need to be running this on the Dom0 and there is, of course, some minor setup to be done by you in the top of the script.
If you have comments, questions or suggestions feel free to pass them along, especially if you are well vested in python since this was my first attempt at using it.

That's an good idea ...
.. and how to configure or debug it ...
my clientlaunch.cfg looks like
[vt] ENVFILE /usr/lib/hobbit/client/etc/hobbitclient.cfg CMD /usr/lib/hobbit/client/ext/mi-vt.py LOGFILE $HOBBITCLIENTHOME/logs/xen.log INTERVAL 5m
but i've got no logfile or something else, nothing to see ..
cheers, martin

I went ahead and sent the same email to the "theshire-developers" list on source forge.

Your client config looks fine - It won't have any console output unless its failing somewhere. Make sure you've set bbhome, domain & hobbit_server in the script.
