check_nt
WindowsのNSClientサービスを使って、様々な値をチェックするプラグイン。
主なものは下記。
- NSClientのバージョン
- CPU負荷
- 稼働時間
- ディスク使用量
- メモリ使用量
- サービスの状態
- プロセスの状態
- ファイルの更新日時から現在までの経過分数
- パフォーマンスカウンタの値

対象ホストに下記が必要
実行
Cドライブの使用容量が 80% で WARNING、 90% で CRITICAL。
/usr/local/nagios/libexec/check_nt -H 192.168.0.2 -v USEDDISKSPACE -l C -w 80 -c 90
ここで、OK, CRITICAL等は表示されないが、ちゃんと終了コードはOK, CRITICALの値をとっているので、
Nagiosに設定するか、下記を実行すれば結果が分かる。
echo $?0
| 終了コード | 結果 |
| -1 | UNKNOWN |
| 0 | OK |
| 1 | WARNING |
| 2 | CRITICAL |

備考
個人的には同様のチェックはNRPE_NTで行うのがお勧めです。
