ESXi开启SNMP服务

ESXi开启SNMP服务方法:

1.使用ssh登陆ESXi主机;
2.切换至/etc/vmware/目录;
3.使用vi打开snmp.xml;
4.将标签false改为
true.
public
5.重启服务
/sbin/services.sh restart

Last night I wrote an article about how to monitor the health of an ESXi server (link here) and I wanted to explain a bit more about my findings with SNMP on an ESXi host.

My goal with the monitoring was to use the check_dell and check_hp commands I have found for Nagios/Opsview to monitor the hardware that ESX is running on. The ESXi installs I am working with are using the Dell and HP management agents installed so I thought that everything would work out of the box and enabling SNMP would let me query the different aspects of the hardware.

The official line from VMWare was that SNMP is not enabled on ESXi and with no console cant be enabled. I knew however, having read a recent post on the TechHead blog (link here) that you could see the snmp.xml file and this shows that it is not enabled which made me think it must be possible to enable it. I was right.

A quick google came up with this article and I had a look and this was a fairly simple process to run:

First you need to enter the “unsupported” console on your ESXi server. To do this press Ctrl+Alt+F1 at your ESX console, now type the word unsupported (N.B. you will not see the text on your screen) and press Enter. If all goes well you should see a password prompt, enter your root password here and you should get a warning you are entering a mode that should only be enabled with VMWare support and be presented with a console.

type the following command to enter the VI text editor and start to modify the snmp.xml file:

vi /etc/vmware/snmp.xml

You should see a single line of text at the top of the screen which is the contents of the xml file. Press i to enter Insert mode and change

false

to

true

Then scroll across and add the community name you want the SNMP agent to respond on and place this between the following tags


so it should look like

public

I wasnt interested in setting up SNMP traps so left this blank and quit the VI editor by press Esc to exit insert mode and then :wq to write the file and quit the editor.

Finally we need to restart the services on the esx host which can be done with the following command

/sbin/services.sh restart

Great, SNMP is now enabled so I should be able to get the information from the HP/Dell management agents that I want. Wrong. My snmpwalk of the host provided little to no useful information about what I was trying to unlock.

My thoughts now are simple. SNMP is not enabled in ESXi for the reason that there is not much there to query and you can use the CIM queries that I mentioned in the previous post to look at this instead.
