Munin 分为master和node 两部分,Munin master为数据中心，Munin node 为节点中心，向master提供数据，master将数据汇总并进行分析。并支持plugin 进行相关程序监控。

2.配置master[/b]
emacs /etc/munin.conf

# Configfile for Munin master
dbdir       /var/lib/munin/
htmldir     /var/www/munin/
logdir      /var/log/munin
rundir      /var/run/munin/

# This is an example of the correct way to activate Nagios warnings
contact.nagios.command /usr/local/nagios/bin/send_nsca nagioshost.example.com -c /usr/local/nagios/etc/send_nsca.cfg -to 60

# From and including the first host, no more global directives can be defined.
# Everything after one host definition belongs to that host, until another host definition is found.

[foo.example.com]             # Defines the group "example.com" and then
                              # "foo.example.com" under that group.
  address localhost           # The address (IP or host name) of the host, where munin-node is running.

[example.com;bar.example.com] # Same as above, but with an explicit definition.
                              # of the host's group.
  address bar.example.com     # The address.
  df.contacts no              # Don't warn Nagios (or whatever) if the 'df' plugin exceed warning values.

[Groupname;]                  # Defines the group "Groupname"
  contacts nagios             # Notifications shall go to nagios for hosts in this group

[Groupname;baz.example.com]   # Associates the host baz.example.com to this group
  address baz.example.com     # The address of the host, where munin-node is running.
  update no                   # Specifies that no services on this host should be updated by munin-update
