ESXi health

This is a collection of ESXi health checkers for Nagios/Sensu. There are two number exposed by rbvmomi and these check against them. This can be used to look directly at a ESXi host and alert on high percentage usage for both CPU and RAM.

Installation

This requires the rbvmomi gem, so in order to run this you need to do something like the following:

$ git clone https://github.com/jjasghar/esxi_health
$ cd esxi_health
$ bundle install

Running

There are multiple way's to run this inside of Sensu/Nagios, but to test via the installation options you can run:

$ cd esxi_health
$ ruby checks/esxi_memory_stats.rb --hostname ESXIHOST -n NAMEOFESXIHOST -P USERNAMEPASSWORD -u USERNAME -p 60
OK: ESXi is under the max memory usage using 60.0%

Sensu Checks

Here is an example Sensu check:

{
  "checks": {
    "esxi_memory": {
      "command": "esxi_memory_stats.rb --hostname ESXIHOST -n NAMEOFESXIHOST -P USERNAMEPASSWORD -u USERNAME -p 60",
      "standalone": true,
      "subscribers": [
        "esxi"
      ],
      "interval": 60
    }
  }
}

Don't forget you'll need to inject rbvmomi into the embedded sensu ruby install:

$ /opt/sensu/embedded/bin/gem rbvmomi
