XYMON – ESX Hardware Health Monitor

Grab the Hardware Health of your VMware vSphere ESXi Host

Here is RC1 of my ESX Health Script for the XYmon monitoring server, not to be compared to the ESXi script going around for VM and Snapshot Health.  ESXHealth monitors the physical health of the hardware running the ESX hyper-visor  This script uses the xymoncgimsg.cgi to send status reports from a remote network to your XYmon Display Server thus allowing you to monitor ESX Host from anywhere really easily. Using this CGI allows you to run it from any windows box and send the notifications through port (http) friendly firewalls.

The only prereqs are, you must have installed the VMWare vSphere Perl SDK and have installed CURL or place the curl-nossl.exe provided in zip in the your PATH on Windows. Your XYmon server must have the xymoncgimsg.cgi moved from the xymon/server/bin folder to your xymon-cgi folder to allow web based status messages.

I have include the curl-nossl portable EXE with zip. Just drop it in the path for windows so you can call it by name. You will need to edit the script and update the URL to send the notifications to. I show an example in the script on how to use with a htpasswd protecting your web CGI for thoes who use that layer of security. If not then just place the standard URL for your xymoncgimsg.cgi and your good to go.

The script is very simple.

If all is good you get a “All’s OK” else if anything is bad it spits out any relevant info about that issue. The last error I got was for redundant Power lost to Supply 1 and was reported with plenty of detail to know what is wrong.

Just schedule windows to run every 15 minutes or so, see script for command line syntax for task scheduler

The monitor will look like the following examples: (Never mind my XYMon theme)

How-to get SNMP Data from VMWare ESXi 5 with Dell OpenManage, Cacti, Nagios, Munin or Ganglia

 

So you want to access your VMware ESX 5 host over SNMP? Here is the quick steps to get Dell OpenManage and SNMP on your ESX 5 host up and running fast.  You will need the VIB’s from Dell, also will need to download and install the VMware CLI client for accessing ESX hosts from remote. For the SNMP setups below we are using a generic password inside of quotes(“password”) you should remove the quotes and place the root password of the esx host where you see the quoted password text. We also are setting up SNMP to send traps to 192.168.24.120, you will need to change this to any host you want to receive traps. You will need to replace the server IP address with the address of your ESX5 host. If you use network monitoring applications like Cacti, Nagios, Munin or Ganglia then this is just what you need to start capturing network statistics and graphs.

 

Steps  to install OpenManage.

  1. Downloaded OpenManage VIB from Dell http://www.dell.com/support/drivers/us/en/g_5/DriverDetails/DriverFileFormats?DriverId=N3R0H&FileId=2773322235
  2. Uploaded VIB to ESX host and placed in /var/log/vmware/
  3. SSH to host as root
  4. ran command esxcli software vib install -d /var/log/vmware/OM-SrvAdmin-Dell-Web-6.5.0-542907.VIB-ESX50i_A02.zip
  5. After software install, I rebooted the host.

Steps to configure SNMP

  1. Started vmWare CLI
  2. vicfg-snmp.pl –server 192.168.24.10 –username root –password “password” -c public
  3. vicfg-snmp.pl –server 192.168.24.10 –username root –password “password” -t 192.168.24.120@161/public
  4. vicfg-snmp.pl –server 192.168.24.10 –username root –password “password” -E
    Current SNMP agent settings:
    Enabled  : 1
    UDP port : 161
    Communities :
    public
    Notification targets :
    192.168.24.120@161/public
    Options :
    EnvEventSource=indications

Openmanage Web Interface:

  1. Download OpenManage Server Administrator Managed Node http://www.dell.com/support/drivers/us/en/555/DriverDetails/DriverFileFormats?DriverId=R300521
  2. Navigate to https://localhost:1311, type in ESX host IP address, login and password.
  3. You should be able to view the all the good stuff like “Main System Chassis”, Software, Storage

 

I hope this helps someone out there in cyber space!
