This is a Nagios plugin, for reporting and checking the normal operation of the ILO port of a HP Server

HP (brand) Servers are typically equipped with a management processor, branded 'ILO' (Integrated Lights Out). This provides remote access and allows the server to the remotely powered on and off.

The server is (usually) unaffected if the ILO processor is faulty, hence the need to check it separately.
### Prerequisites

* If you have a HP Server with an ILO Management processor,
* If you have installed the HP SNMP Agents for reporting on the server health

Then this plugin is for you

### What it does

This script:
* connects to the server using SNMP version 2c using the snmpget command, and fetches the IP address of the ILO network port.
* connects to this ILO IP address using HTTPS, and checks the Title and Server headers of the HTTP response, to ensure an ILO device is present.

For the script to work properly, the HP SNMP Agents must be install and working on the server OS,
and the ILO Network port must be accessible (ie. not blocked by a firewall or VLAN access rules or IP routing rules)

The correct SNMP community string must be provided to the script (default: public)

#### Sample Output (normal)

OK: ILO=, iLO 4, HP ILO found: HP-iLO-Server/1.30|time=0.3165

#### Sample Output (ILO Port not accessible)

CRITICAL: ILO=, HTTP Error: 500 Can't connect to (timeout), (!) HTTP reponse took 10.1s (> 10.0s)|time=10.1294
Note that the IP above is for the ILO, not the server specified by -H

#### Sample Output (SNMP not responding / wrong community string)

CRITICAL: ILO=not available, Timeout: No Response from|time=U

Note that the Hostname/IP above is for the server, not the ILO

### Sample config

define command {
command_name check-hp-ilo
command_line $USER1$/ -H $HOSTADDRESS$ $ARG1$

define service {
use generic-service ; template name
service_description hp-ilo
hostgroup_name hp-servers
check_command check-hp-ilo!-c not_so_public
stalking_options o,w,c ; Retain latest ILO IP address (output rarely changes)

define hostgroup {
hostgroup_name hp-servers

define host {
use generic-host
name hp-server-0001
hostgroups hp-servers

### Performance Data

This plugin measures the response time of the ILO HTTPS Response (excluding the time taken for the SNMP response).
This is the only performance data generated, and works with the default PNP4Nagios template.
