munin df插件配置

Question

每次删除LVM快照时，都会收到Munin警告：

Disk latency per device :: Average latency for /dev/vg/lv_mysql_snapshot
UNKNOWNs: Read IO Wait time is unknown, Write IO Wait time is unknown.

Disk latency per device :: Average latency for /dev/mapper/vg-lv_mysql-real
UNKNOWNs: Read IO Wait time is unknown, Write IO Wait time is unknown.

Disk latency per device :: Average latency for /dev/mapper/vg-lv_mysql_snapshot-cow
UNKNOWNs: Read IO Wait time is unknown, Write IO Wait time is unknown.

是否可以忽略munin中的LVM分区通知？ 感谢。

Answer 1

在你的情况下快速：

  [diskstats]
    env.exclude lv

应该足够了。这应该放在这个主机配置下面的/etc/munin/munin.conf中。
