Re: [Xen-users] xm top

[Mark Williamson <mark.williamson@xxxxxxxxxxxx>]

xm top really invokes the xentop command

xentop gets its information from libxenstat...  This is a C library, although 
there are swig-based bindings for Perl and Python provided.  If you feel 
enterprising you could try to hack up a PHP binding...

Otherwise, your best bet for a quick-n-dirty is probably to get the 
information out either using libvirt or using libxenstat (by writing a little 
script in a language which has bindings), then dump that to a stdout / a file 
and access it in PHP.

Cheers,
Mark
