Hello, I wonder if there is any possibility to show the load average of a whole XEN server. Executing top in Dom0 or DomU only shows the load average of the according domain but there seems to be no way to show the load of the whole server. How to check if a server is over load because the domains running on it where frequented too much? Did I miss something? Any help appreciated.

Hello Mats,> "xm top" should do what you want, I would think.--- xm top Error: Unknown command: top Try ''/usr/sbin/xm help'' for more information. --- Looks like it doesn''t. I''m using xen-2.0.7-stable, perhaps the feature you mentioned exists in versions >= 3 ?!

I think there''s a synonymous command of "xentop", but that may also be a version >= 3 command... -- Mats> > > Cheers, > > -- > Christian Hertel > Netzwerk-Sicherheit/Netzwerk-Applikationen > > infoServe GmbH > Nell-Breuning-Allee 6 > D-66115 Saarbruecken > > T: (0681) 8 80 08 - 59 > F: (0681) 8 80 08 - 33 > www.infos.de > mailto:c.hertel@infos.de_______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

There''s a package called vmtools for xen which claimed to report useful stuff about load, but I could never get it to work. I don''t have the link handy with me at the moment. I also use the xm list command, and then use a neat graphing package (xenupdate.py, xengraph.py) -- not a precise way of monitoring but it provides some perspective about load distribution.
