Enable snmp on VMware vSphere Hypervisor 5.1(vicfg-snmp)

無償版のVMware vSphere Hypervisor 5.1のsnmpをコマンドから有効にできるか確認してみました

VMware vSphere Hypervisor
http://www.vmware.com/jp/products/datacenter-virtualization/vsphere-hypervisor/overview.html

VMware vSphere Hypervisor 5.1にvMA5.0をデプロイしてvicfg-snmpコマンドで設定してみます

1. sshでvMA5.0にログイン

sshクライアントからvMA5.0にログインします

2. Hypervisor 5.1を登録

snmpを有効にするHypervisor hostを管理サーバに登録します

vi-admin@vma5:~> vifp addserver vmesxi.rootlinks.net

vi-admin@vma5:~> vifp listservers
vmesxi.rootlinks.net ESXi

3. ターゲットを指定

管理hostを指定します

vi-admin@vma5:~> vifptarget -s vmesxi.rootlinks.net

4. vicfg-snmp

snmpを設定するvicfg-snmpコマンドの使用方法です

vi-admin@vma5:~[vmesxi.rootlinks.net]>vicfg-snmp --help Synopsis: /usr/bin/vicfg-snmp OPTIONS Command-specific options: --communities -c Set communities separated by comma comm1[,...] (this overwrites previous settings) --disable -D Stop SNMP service --enable -E Start SNMP service --hwsrc -y Where to source hardware events from IPMI sensors or CIM Indications.

5. vicfg-snmp -s

以前、直接/etc/vmware/snmp.xmlファイルを編集してsnmpを有効に設定したのでコマンドで確認してみます

vi-admin@vma5:~[vmesxi.rootlinks.net]> vicfg-snmp -s
Current SNMP agent settings:
Enabled : 1
UDP port : 161

Communities :
public

Notification targets :

Options :
EnvEventSource=indications
engineid=00000063000000a1c0a80a00
loglevel=info

6. trapの設定

試しにtrap先を設定してみます

vi-admin@vma5:~[vmesxi.rootlinks.net]> vicfg-snmp -t 192.168.1.254/public
Changing notification(trap) targets list to: 192.168.1.254/public…
Failed : Current license or ESXi version prohibits execution of the requested operation.

無償版のHypervisor 5.1ではコマンドでの参照は出来ますが設定変更は出来ませんでした
無償版のHypervisor 5.1でsnmpを有効にするには直接ファイルを編集するしな無いようです
