# 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";'`

|
||||
# - Add dynamic arch page size determination
|
||||
# - Some cleanup and clarification
|
||||
# version 0.3 - 2006 May 3 - Micah Anderson <micah@riseup.net>
|
||||
# - Add ability to group vservers via environment vars
|
||||
# - Fix missing close quotes and standardize indents
|
||||
# - Add limit notification
|
||||
# - Update documentation to include info on groups and limits
|
||||
# version 0.4 - 2006 Jun 22 - Micah Anderson <micah@riseup.net>
|
||||
# - Fix error that results if NodeName is set to include a domain name
|
||||
# version 0.5 - 2008 Apr 12 - Chris Wilson <chris+munin@qwirx.com>

||||
# - Some cleanup and clarification
|
||||
# version 0.3 - 2006 May 3 - Micah Anderson <micah@riseup.net>

# - Fix error that results if NodeName is set to include a domain name

# Graph Vserver resource usage and limits
|
||||
#
|
||||
# Configuration variables
|
||||
# vservers - specify the vservers to include in the graph (default: all)
|
||||
# resource - specify the resource to be monitored (no default)
|
||||
# limits - if true, turn on limit graphing (default: false)
|
||||
#
|
||||
# NOTE: If no configuration variables are set, the defaults will be used
|
||||
|
||||
# Example /etc/munin/plugin-conf.d/munin-node
|
||||
#
|
||||
# The following monitors the RSS value for the vservers named
|
||||
# "vserver1 vserver2 vserver3 vserver4" and looks to see if the
|
||||
# resource limit has been breached, if so it sends a message to nagios
|
||||
# via send_nsca, and sends an email to notify that this has happened:
|
||||
#
|
||||
# [vserver_resources]
|
||||
# user root
|
||||
# env.vservers vserver1 vserver2 vserver3 vserver4
|
||||
# env.resource RSS
|
||||
# env.limits 1
|

# contacts nagios email
|

# contact.nagios.command /usr/bin/send_nsca -H your.nagios-host.here -c /etc/send_nsca.cfg
|
||||
# contact.email.command mail -s "Munin-notification for ${var:group} :: ${var:host}" your@email.address.here
|
||||
#
|
||||
# This second example monitors the VM value for all vservers on the system and
|
||||
# has no limit notifications turned on:
|
||||
#
|
||||
# [vserver_resources]
|
||||
# user root
|
||||
# env.vservers vserver5 vserver6 vserver7
|
||||
# env.resource VM
|
||||
# env.limits 0
|
||||
#
|
||||
# This last example monitors all the resources for vserver5. Note that
|
||||
# this will be a busy graph, and it would be really useless if you
|
||||
# specified more than one vserver when the resource is set to ALL:
|
||||
#
|
||||
# [vserver_resources]
|
||||
# user root
|
||||
# env.vservers vserver5
|
||||
# env.resource ALL
|
||||
# env.limits 0
|
||||
|
||||
# Possible values for env.resource are:
|
||||
#
|
||||
# ALL - all the below resources
|
||||
# PROC - number of processes
|
||||
# VM - sum of all virtual pages inside the guest
|

# VML - sum of all virtual pages locked into memory
|

# RSS - number of pages currently present in RAM

|

# (for one vserver only)
|

# - and/or make it so you can graph all resources for one vserver
|

# - set a default for the resource if it is unset?
|

# - 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";'`
