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
