# Graph Vserver cpu usage stats
#
# Configuration variables
# vservers - specify the vservers to include in the graph (default: all)
#
# NOTE: If no configuration variable is set, the default will be used
#
# see vserver_resources for example uses of configuration files
#
# or links to define what to monitor:
# vserver_cpu_ -> monitor cpu usage of all vservers on all cpus
# vserver_hold_ -> monitor hold on all vservers on all cpus
# vserver_hold_0 -> monitor hold on all vservers on cpu0
# vserver_hold_1 -> monitor hold on all vservers on cpu1
# vserver_hold_foo -> monitor hold on all cpus on vserver named foo
# vserver_sys_foo -> monitor cpu usage on all cpus on vserver named foo
# Changelog
# version 0.2 - 2006 October 02 Holger Levsen <debian@layer-acht.org>
# - label fixed: we measure jiffies not seconds
# - Fix error that results if NodeName is set to include a domain name
# - Fix hypens in NodeNames, replace them with underscores
# - whitespace cleanup
# version 0.3 - 2006 October 07 Holger Levsen <debian@layer-acht.org>
# - rewrite of vserver_usercpu
# - smp-aware
# - can display hold too (third value in the cpu line(s) of /proc/virtual/<xid>/sched)
# - no seperation between user and system cpu anymore
# - handle identical vserver-names by using the vserver-id internally
# version 0.4 - 2007, October 07
# Micah Anderson <micah@riseup.net>
# - fixed variable name (thanks pietro)
# version 0.5 - 2008, July 07
# Micah Anderson <micah@riseup.net>
# - fixed number of CPU regexp to be more accurate
# - added $NAMELOC - fixes plugin so it works with VCI_SPACES (> 2.6.19) as well as older version
# TODO:
# - comment the code or go mad
# - add info how many jiffies per second are available on a machine
# - user and system cpu are always added to each other, make it optional to split them?
# - use /proc less often (100 times more overhead than talking to the kernel directly)
# i.e. use something like pagesize=`perl -MPOSIX -e 'print POSIX::sysconf(_SC_PAGESIZE), "\n";'`
