ESXiのハードウェアを監視します。対象としては、DellやIBM、HPのサーバなどです。あまりにマイナーなハードウェアだとほとんど監視できませんので、あしからず。

Nasgios Exchangeにも書かれていますが、どうも、ESXi 5.0 u1ではCIMのクエリに対する応答が異常に遅くなるバグがあるようです。プラグインのバグではないとの記載があります。私が試してみたところ応答があるまでに1分30秒以上かかり、結果プラグインの実行がタイムアウトしてしまいます。nagios.cfgのservice_check_timeoutをデフォルトの60秒から300秒程度まで伸ばして、監視間隔を10分など長めに設定すると問題ないようです。

動作確認は、CentOS 6.2 + ESXi 4.1, 4.1 u1, 5.0, 5.0 u1です。

ESX側には、監視用のユーザを作成する必要がありますので、まずは、システム管理者のロールかrootグループに所属するユーザを作成してください。

作成者のサイトか、Nagios Exchangeからcheck_esxi_wbem.pyをダウンロードします。pluginsのディレクトリに移し権限を付与しておきます。

export http_proxy=http://xxx.xxx.xxx.xxx:8080# プロキシが必要な場合だけ
wget http://www.claudiokuenzler.com/nagios-plugins/check_esxi_hardware.py
mv check_esxi_hardware.py /usr/lib64/nagios/plugins
chmod 755 /usr/lib64/nagios/plugins/check_esxi_hardware.py

このスクリプトの動作には、vSphereCLIとpython、pywbemが必要です。
まず、python、pywbemをインストールします。

yum install python pywbem

次にvSphere CLIをインストールします。
ダウンロードには登録が必要です。ログインしたあと、vSphereCLIをダウンロードします。今回は、「VMware-vSphere-CLI-5.0.0-422456.x86_64.tar.gz」をダウンロードしました。

cd /usr/local/src
tar xzvf VMware-vSphere-CLI-5.0.0-422456.x86_64.tar.gz
cd vmware-vsphere-cli-distrib/

インストールの前に色々とパッケージが必要となるので、先にインストールしておきます。また、接続にプロキシが必要な場合はproxyも設定しておきます。(ftpも)

export http_proxy=http://xxx.xxx.xxx.xxx:8080
export ftp_proxy=http://xxx.xxx.xxx.xxx:8080
yum install openssl-devel libxml2-devel libuuid-devel
cpan # ←初回起動時は色々聞いてきます。
 cpan > o conf ftp_proxy http://xxx.xxx.xxx.xxx:8080
 cpan > o conf http_proxy http://xxx.xxx.xxx.xxx:8080
 cpan > install YAML
 cpan > install UUID
 cpan > install LWP::Protocol::https

やっとインストールです。途中何度か質問を投げてくるので、適当に適切に答えます。

./vmware-install.pl
Press enter to display it. [enter]
Do you accept? (yes/no) yes
In which directory do you want to install the executable files?
[/usr/bin] [enter]

それでは実行してみましょう。ユーザとパスワードは先ほど作成したものを使用します。

verboseを指定したため、上記のようなちょっと詳細な結果が帰ってくるはずです。。。しかし、さすがに自作パソコンだけあって、FanもPowerSupplyもBatteryも、ほとんど何も監視できていない。CPUくらいか・・・。
ちなみに、普通のサーバ(DellやIBM、HPなど)を使用すれば温度センサーやバッテリーのステータス、PowerSupplyのステータスなど、様々な値が帰ってくるようになります。また、「–perf-data」を指定しているため、温度や回転数など取得できるパフォーマンスデータがあれば、一緒に帰ってきます。

上記スクリプトをNagiosのCommandファイルと、Servicesファイルに追加し監視してください。

ちなみに、対応したハードウェアに対して上記スクリプトを実行すると、下記のようなにこれでもかと応答が帰ってきます。ハードウェアの監視としてはコレで十分すぎるくらいではないかと。
