Adaptec RAID Monitoring Plugin setup

The Adaptec RAID Monitoring Plugin can be used to monitor Adaptec Controller RAID sets. The plugin is written in Perl and uses the command line tool arcconf to interact with the controller.

Current Version

The current check_adaptec_raid version can be obtained from GitHub:

Prerequisites

A detailed description on how to install the requirements will follow in the next sections:

On the monitored server
- Install check_adaptec_raid plugin
- Install arcconf
- Install libfile-which-perl
- Add sudoers entry for user nagios to call arcconf without sudo password
- If NRPE is used a command definition for NRPE
On the Icinga server
- Command definition
- Service defintion
- If using the Call-Home-Service
  - Define templates (Using Call-Home-Service with Icinga or Nagios)

Installation

Manually

Installing the plugin manually involves copying the file into the directory /usr/lib/nagios/plugins.

:~$ git clone https://github.com/thomas-krenn/check_adaptec_raid.git
Cloning into 'check_adaptec_raid'...
:~$ cd check_adaptec_raid/
:~/check_adaptec_raid$ ls
arcconf_output  check_adaptec_raid  check_adaptec_raid.POD  README  testing.patch
:~/check_adaptec_raid$ sudo cp check_adaptec_raid /usr/lib/nagios/plugins/

The command line utility arcconf can be found for the corresponding adaptec controller on their website: http://www.adaptec.com/en-us/downloads/

TK Ubuntu-Repository

After setting up the Repo - Thomas Krenn Ubuntu Repo - the package nagios-plugins-thomas-krenn installs check_adaptec_raid:

:~$ sudo apt-get install nagios-plugins-thomas-krenn
[...]
Suggested packages:
  arcconf

  arcconf libstdc++5 libfile-which-perl

Configuration

The plugin is suited to monitor a host via NRPE as well as a local host. In both cases the plugin has to be installed on the monitored server.

Via NRPE

One the Icinga Server

The host definition defines the command that is called via NRPE on the remote host. The plugin parameters are specified on the remote host afterwards:

define service {
    service_description           adaptec-raid-nrpe
    display_name                  Adaptec RAID
    use                           generic-service
    host_name                     test
    check_command                 check_nrpe_1arg!check_adaptec_raid
}

Attention: In order to use the Call-Home-Service some templates have to be created - cf. Using Call-Home-Service with Icinga or Nagios. Then instead of use generic-service, the line use thomas-krenn-service must be used at service definition!

Using TKmon to configure check_adaptec_raid

The Adaptec raid plugin is already integrated in the TKmon service catalogue. It is sufficient to select "Adaptec RAID via NRPE" when adding a service to a host:

On the monitored Server

The user nagios has to call arcconf without providing a sudo password. Therefore the following sudoers definition is created.

Attention: With CentOS the NRPE daemon runs as user nrpe! Therefore you have to replace nagios with nrpe in the sudoers configuration.

:~$ sudo vi /etc/sudoers.d/check_adaptec_raid 
nagios ALL=(root)NOPASSWD:/sbin/arcconf
:~$ sudo chmod 440 /etc/sudoers.d/check_adaptec_raid

If the definition is correct, the following command does not ask for a password:

:~$ sudo su nagios --shell /bin/bash
:~$ sudo /sbin/arcconf --version
  | UCLI |  Adaptec by PMC uniform command line interface
  | UCLI |  Version 7.0 (B18781)
  | UCLI |  (C) Adaptec by PMC 2003-2011
  | UCLI |  All Rights Reserved
[...]

A NRPE configuration file specifies the check command that is called if check_adaptec_raid is used via NRPE. This command must be the same as the one on the Icinga side in the host definition.

Notice: With CentOS it may help to specify the script interpretor explicitly, e.g. perl /usr/lib/nagios/plugins/check_lsi_raid -C 0 -p /usr/sbin/storcli.

:~$ sudo vi /etc/nagios/nrpe.d/raid.cfg
command[check_adaptec_raid]=/usr/lib/nagios/plugins/check_adaptec_raid -C 1 -p /sbin/arcconf

:~$ sudo service nagios-nrpe-server restart

Finally a test on the Icinga side checks the correct definitions:

:~$ /usr/lib/nagios/plugins/check_nrpe -H 10.0.0.2 -c check_adaptec_raid
AACRAID OK (Ctrl #1)

Check local RAID

A local check is useful if the Icinga server itself uses an adaptec RAID controller.

Manually

Requirements for a local installation are the plugin, arcconf and the sudoers entry. As a first step an Icinga command definition is created:

:~$ sudo vi /etc/nagios-plugins/config/check_adaptec_raid.cfg
define command {
        command_name    check_adaptec_raid
        command_line    /usr/lib/nagios/plugins/check_adaptec_raid -C '$ARG1$' -p '$ARG2$'
}

A service definition uses this command:

define service{
        use                             generic-service
        host_name                       tkmon
        service_description             adaptec-raid
        check_command                   check_adaptec_raid!1!/sbin/arcconf
}
