[libvirt] Performance statistics
Hello, Is it possible to get at the (historical) performance data provided by libvirtd? Is it stored for a period of time, or only available to clients polling it? Thanks JB

Libvirtd doesn't store any, you really need to poll at the frequency you consider appropriate, Daniel -- Daniel Veillard | libxml Gnome XML XSLT toolkit http://xmlsoft.org/ daniel@veillard.com | Rpmfind RPM search engine http://rpmfind.net/ http://veillard.com/ | virtualization library http://libvirt.org/

FYI, you can use 3rd party monitoring software with a libvirt data collection plugin. We have written plugins for collectd, munin and nagios - it is trivially to do the same for more monitoring apps if one of those doesn't suit your needs Daniel -- |: Red Hat, Engineering, London -o- http://people.redhat.com/berrange/ :| |: http://libvirt.org -o- http://virt-manager.org -o- http://ovirt.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: GnuPG: 7D3B9505 -o- F3C9 553F A1DA 4AC2 5648 23C1 B3DF F742 7D3B 9505 :|
