Monitoring the VMware ESXi with Nagios (1)

オープンソースのコンピュータシステムおよびネットワーク監視のためのNagiosからVMware ESXiを監視する設定をしてみました

VMware ESXiの監視にはいくつか方法がありますが、今回はCheck VMware APIを使用しました

1. VMWare Perl SDKインストール

Check VMware APIを動作させるためにはVMWare Perl SDKが必要になります
今回はVMware-vSphere-SDK-for-Perl-4.0.0-161974.i386.tar.gzをダウンロードしてインストールを行いました

Shell

最初は最新のVMware-vSphere-Perl-SDK-5.0.0-422456.i386.tar.gzをインストールしたのですがMissing perl module VMware::VIRuntimeのエラーがでて、メッセージにあるようにVMware-vSphere-SDK-for-Perl-4.0.0-161974の32bit版をインストールし直しました

2. VMware API projectのダウンロード

VMware API projectからスクリプトをダウンロードします
参考サイトでは”check_esx”となっていますが名前が変わって”check_vmware_api.pl”になっています

3. check_vmware_api.plをコピー

check_vmware_api.plをNagiosのコマンドフォルダにコピー(あるいは移動)させます
私の場合はソースからインストールして特にインストールフォルダの変更は行っていないので”/usr/local/nagios/libexec”になります。また、実行権限の無い場合は追加して下さい

Shell

[root@host1 ~]# cp op5plugins/check_vmware_api.pl /usr/local/nagios/libexec/ [root@host1 ~]# ls -l /usr/local/nagios/libexec/check_vmware_api.pl -rwxr-xr-x 1 nagios nagios 167291 8月 19 21:41 libexec/check_vmware_api.pl

4. check_vmware_api.plの実行

取り敢えずcheck_vmware_api.plを実行してみます
Can’t locate Nagios/Plugin/Functions.pmとエラーが出てしまいました

あるいは場合によってはCan’t locate Params/Validate.pmとエラーが表示されるかもしれません

まだNagios::Plugin perl moduleが必要でした。次回これをインストールします

How do I use the Nagios::Plugin perl module?
