「DELLサーバのRAIDを監視してmuninでメール通知」の助けになれば


DELLサーバのRAIDを監視してmuninでメール通知
素晴らしい手順エントリで、最後のオチも良かったのでw


さっきのエントリの途中まで実行し、omreportコマンドが実行出来る様になったら、

[oranie@hogehoge]# omreport storage pdisk controller=0

で物理Disk状態が見れて、

[oranie@hogehoge]# omreport storage vdisk controller=0

で仮想Disk(Raidね)の状態が見れるので、例えばこれをcronで1分に1回とか適当なディレクトリに
出力しておいて、それをWebサーバで見れるようにして、監視サーバが
http://example.com/pdisk.txt
http://example.com/vdisk.txt
で取得できるようにするとか、sshコマンドで直接叩くとか、NagiosだったらNRPE使うとかで
簡単なOK、NG判定のスクリプトを叩く事で正常性を確認して、NGならメール飛ばすとかでどうですかね?
たとえばこんなのをcronで1時間に1回とか。
https://github.com/oranie/oranie/blob/master/shell/dell_raid_check.sh

というか、既にNagiosプラグインであるよとかもっとちゃんとした方法とかあれば教えて下さい><
