sensu_dell

This is a Sensu check (dell_check.rb) designed to verify status of several components of a dell server.
This removes the need to have NRPE (Nagios) installed and wrapping a Perl script which wraps openmanage. Yo dawg, I heard you like wrapping..

Requirements

This requires Dell Openmanage is installed. The command omreport must be in your path, or you can set a default binary path within a json blob.
Example: /etc/sensu/conf.d/dell_check.json

{ "dell_check": { "binpath":"/path/to/openmanage"} }

Installation

Copy dell_check.rb to a friendly Sensu check execution path on all target assets.

mkdir -p /etc/sensu/plugins/hardware/
cp dell_check.rb /etc/sensu/plugins/hardware/dell_check.rb
chmod 755 /etc/sensu/plugins/hardware/dell_check.rb

Check Example

For instance, create check /etc/sensu/conf.d/checks/dell_memory_check.json

 {
  "checks": {
    "dell_memory_check": {
     "command": "/etc/sensu/plugins/hardware/dell_check.rb --memory",
      "subscribers": [
        "linuxhost"
      ],
      "interval": 15
    }
  }
 }

Plugin details

This initial stab at a plugin using the periodic check method that is common in Nagios and Sensu. We will eventually replace this for a local daemon that runs on an asset, and will send alarms directly through the client Sensu socket. The framework for this daemon is forthcoming, but we'd like a local alarmbot that will listen to things like hardware events or syslog messages, and fire off notification on-demand rather than on a periodic schedule (push instead of poll). We can add double-verification by including concurrent periodic polling as a point of parity with the push notifications.

Items Verified

storage, check the storage subsystem
memory, check system memory (dimms)
fans, check fan status
power, check power supplies
temperature, check chassis temperature sensors
cpu, check processors
voltage, check chassis/systemboard voltage sensors
batteries, check battery probes
amperage, check power consumption
intrusion, check for intrusion detection
sdcard, check removable flash media (SD cards)
alertlog, check alert log
esmlog, check the ESM log (hardware log)
esmhealth, check the ESM log overall health
servicetag, check that the service tag is sane
