+=head1 NAME
+
+check_areca - Checks the status of an Areca RAID via the Areca CLI utility.
+
+=head1 VERSION
+
+This documentation refers to check_areca version 1.1.0
+
+=head1 USAGE
+
+check_areca.pl
+
+=head1 REQUIRED ARGUMENTS
+
+None
+
+=head1 OPTIONS
+
+ --areca_cli (-A) Set the location of the Areca cli executable.
+ --help Display usage information.
+ --man Display the entire POD documentation
+ --timeout (-t) Sets the timeout, defaults to 10 seconds.
+ --usage Display usage information (same as --help)
+ --version Display the version number
+
+
+=head1 DESCRIPTION
+
+This is a Nagios plugin that runs the Areca CLI to check the status of the
+RAID controller. It then parses the resultant exit information and
+passes the output to NRPE.
+
+=head1 DIAGNOSTICS
+
+=head2 Command: cli vsf info failed, aborting!
+
+For some reason the command trying to be run failed. Try running it by hand
+and seeing if it runs properly.
+
+=head2 Operation timed out after <timeout> seconds.
+
+Running the command failed after a certain amount of time (defaults to 10
+seconds). Try using the --timeout (-t) switch and increasing the timeout
+threshold. Also try running the command by hand and see if it is hanging.
+
+=head2 An unknown error has occurred:
+
+Just what it says, running the cli command threw an unknown error and the
+process died. Run the CLI command by hand and see if you receive proper
+output.
+
+=head2 <areca cli> does not exist, aborting!
+
+The binary that the script is looking to run does not exist. By default
+check_areca looks in /usr/local/areca/bin/ for the cli. However, you can
+change this default by setting the --areca_cli (-A) flag from the command
+line
+
+=head2 <areca cli> is not executable by the running user, aborting!
+
+The cli program was found but it is not executable by the current user,
+usually this is the nagios user.
+
+=head1 CONFIGURATION AND ENVIRONMENT
+
+The Areca cli program should be available on the system. By default
+check_areca looks in /usr/local/areca/bin/cli for the cli. You can set the
+location using the --areca_cli (-A) flag from the command line.
+
+It is helpful to have an Areca RAID controller on the system being checked.
+

+ POSIX Standard Perl 5.8 module
+ Getopt::Long Standard Perl 5.8 module
