Xen users - Mar 2006 - xenmon stats

Hi,
Can someone clarify for me the numbers that show up in Xenmon? Specifically,
I''m curious about the
"domain31" entry which always shows up.  It looks like this represents
the
free resources.  Also, does anyone know what would happen if more than 30
domain0''s were started (or more likely, I did enough migrations to
raise the
next domain ID to above 30)?

Thanks for the clarifications!

And generally, are people using xenmon to monitor performance, or do you
generally stick with things like xentop or even measurement apps inside the
unpriveliged domains like "top" or "vmstat"?

-Tim

Err, thats just us being lazy :-) "Domain31" is just another name for
the idle domain. 32 is kind of hard coded in the current
implementation as the maximum number of domains xenmon can keep track
of. Its good that you brought it up -- I''ll think about whats a clean
way of going about this. But yes, if your domain IDs go beyond 31,
funny things might happen.
