muninでしきい値を超えた時にメールを送れるようなので設定してみました。

＜環境＞
Centos 6.3
Munin version 2.0

ハードディスク容量でテストしてみます

今の状態は

# munin-run df
_dev_vda3.value 2.72093653752988
_dev_shm.value 0.0282237832413447
_dev_vda1.value 21.9097563361532

設定を確認

# munin-run df config
graph_title Disk usage in percent
graph_args --upper-limit 100 -l 0
graph_vlabel %
graph_scale no
graph_category disk
_dev_vda3.label /
_dev_vda3.warning 92
_dev_vda3.critical 98
_dev_shm.label /dev/shm
_dev_shm.warning 92
_dev_shm.critical 98
_dev_vda1.label /boot
_dev_vda1.warning 92
_dev_vda1.critical 98

設定を変えます

# vim /etc/munin/munin.config

+ contact.email.command mail -s "Munin ${var:host}" sample@example.com
+ contact.email.max_messages 10
+ contact.email.always_send warning critical

[localhost]
    address 127.0.0.1
    use_node_name yes
+    df._dev_vda3.warning 1
+    df._dev_vda3.critical 2

テストメールを送ってみる

sudo -u munin sh -c "/usr/share/munin/munin-limits --contact email --force"

下記のようなメールが届きます

	OKs: /boot is 21.91, /dev/shm is 0.03, / is 2.72.
