munin df插件配置

Question

每次删除 LVM 快照时，我都会收到 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.

有什么方法可以忽略 munin 中的 LVM 分区通知？ 谢谢。

Answer 1

在你的情况下快速：

  [diskstats]
    env.exclude lv

应该够了。这应该放在此主机配置下方的 /etc/munin/munin.conf 中。
