Hello,
my Vbox v3.1.2 is running on Linux Ubuntu Desktop 9.10 as a host
system, as a guest system i use Ubuntu Server 9.10 with Guest
Additions installed.
I tried to write a function on Python which returns information about
the OS running inside the virtual machine, for this purpose i was
going to use methods of IGuest interface.
The statistics stuff was only implemented for Windows guests. For others
it's still on the todo list (low priority).
So the behavior you see is about as good as it gets. The only thing I
can't explain is the odd error code you get.

At first i tried to modify existing vboxshell.py script in order to
implement own function 'stats3':
----
def stats3Cmd(ctx, args):
print args
vers = ctx['vb'].version
print "Version is", vers
if (len(args) < 2):
print "usage: stats3 [vmname|uuid]"
return 0
mach = argsToMach(ctx,args)
if mach == None:
return 0
os = ctx['vb'].getGuestOSType(mach.OSTypeId)
print " Name [name]: %s" %(mach.name)
print " ID [n/a]: %s" %(mach.id)
print " OS Type [n/a]: %s" %(os.description)
manager = ctx['mgr']
vb = ctx['vb']
session = manager.getSessionObject(vb)
if mach.sessionState == ctx['ifaces'].SessionState_Open:
vb.openExistingSession(session, mach.id )
else:
vb.openSession(session, mach.id )
console = session.console
guest = console.guest
guestadd_ver1 = guest.additionsVersion
print guestadd_ver1
cpu = 0
threads = guest.getStatistic( cpu, 4 )
print threads
return 0

after execution this function i've got the following traceback:

after this i tried to implement this function to work over vboxwebsrv,
but .. no luck again:

was anyone able to implement any function with use of getStatistic method?
if yes, any example of getStatistic use will be very appreciated.
Thanks.
