# Version : 1.0 or 1315 2009-01-08 09:16:31Z
# Date    : January 8 2009
# Notes   : This is the original plugin 
#
#
# Version : 2011-03-24
# Date    : March 24 2011
# Notes   : Modified plugin to perform a Percentage Of Dirty Pages check that
#			returns performance data (cache_pdp)
#
# Version : 2011-03-28
# Date    : March 28 2011
# Notes   : Modified plugin to perform SP Busy and SP Idle checks that
#			returns performance data (sp_busy and sp_idle)
#
#
# Version : 2011-05-08
# Date    : May 5 2011
# Notes   : Modified plugin to peform an SP Busy check [that uses the controller
#			busy and idle ticks] and returns performance data (sp_cbt_busy).
#			This is more accurate than the (sp_busy and sp_idle) method.
#			Removed (sp_busy and sp_idle) checks from the help text, left them
#			in the plugin so can can still be used if desired.
#
#
# Version : 2011-06-29
# Date    : June 29th 2011
# Notes   : Modified sp_cbt_busy to check for negative numbers in the data
#			obtained from the SAN. If this occurs then abort. This happens 
#			randomnly so this will avoid incorrect data.
#
#
# Version : 2011-07-04
# Date    : July 4th 2011
# Notes   : Modified sp_cbt_busy to ensure calculated value does not exceed
#			100%. If this occurs then abort. This happens randomnly so this 
#			will avoid incorrect data.
#
#
# Version : 2012-03-06
# Date    : March 6th 2012
# Notes   : Modified check_disk to look for Removed drives, this was missing.
#			Also removed a double || symbol in the same section.
#			Modified check_portstate to include code supplied from Federspiel
#			Till. Problem occurred when all ports were checked, the error_count
#			was being incorrectly determined.
#
#
# Version : 2012-10-23
# Date    : October 23rd 2012
# Notes   : Corrected POD formatting to fix POD ERRRORS.
#			Added error checking to ensure we are getting expected results from
#			the Navisphere CLI app.
#			
#
# Version : 2012-12-05
# Date    : December 5th 2012
# Notes   : Updated plugin to check for navicli or naviseccli, it will use
#			naviseccli if present. Also makes sure that the username and password
#			arguments have been provided. This fixes a problem with newer
#			releases of Navisphere that only come with naviseccli (reported by
#			Charles Breite).
#			
#			
# Version : 2012-12-11
# Date    : December 11th 2012
# Notes   : Fixed bug in portstate check, it is now performing a regex that is 
#			not case sensative (reported by Charles Breite). Also added a check
#			to detect if the user did not provide any options, if not it will
#			display the help. 
#			
#			
# Version : 2012-12-19
# Date    : December 19th 2012
# Notes   : Updated code to prevent errors if required arguments are missing, if 
#			so it will display the help. Updated the help to include information
#			about Secure vs Non-Secure and also provided several examples.
#			
#			
# Version : 2013-01-25
# Date    : January 25th 2013
# Notes   : Added LUN check (requested by Nishith N. Vyas) to report the State,
#			ID, Name, Size, Free Space, RAID Group Type and Percentage Rebuilt. 
#			Added RAID Group check (requested by Nishith N. Vyas) to report the
#			State, ID, RAID Group Type, Logical Size, Free Space, Percentage 
#			Defragmentation Complete, Percentage Expansion Complete. 
#			Fixed bug in the disk check that was counting Empty disk slots as
#			disks, (reported by Nishith N. Vyas). Added SP Information check 
#			that will report information about the SP ID, Agent Revision, 
#			FLARE Revision, PROM Revision, Model/Type, Memory and Serial Number.
#			Added functionality that will pause for 7 seconds if an error occurs
#			before showing the help text, this gives you time to read the error
#			message. Added error checking for "Could not connect to the specified
#			host". Updated SP check to account for enclosures which return 
#			certain parts (Fans etc) with a status of N/A (as reported by 
#			davesykes on Nagios Exhcange). Added information to the Help about 
#			what states will be returned for each check. If warn or crit values
#			are incorrect or not present when the arguments are, only an error
#			is displayed, the help is not displayed. Fixed bug "Illegal division
#			by zero" error when running the sp_cbt_busy check (reported by
#			Charles Breite). Added full GNU license.
#			
# Version : 2013-01-28
# Date    : January 28th 2013
# Notes   : Fixed RAID Group type being identified as hot_spare instead of 'Hot
#			Spare'. 
#			
# Version : 2013-01-30
# Date    : January 30th 2013
# Notes   : Removed space from performance data string for LUN and RAID Group
#			checks as identified by Fernando Coelho.
#			
#
# Version : 2013-02-09
# Date    : February 9th 2013
# Notes   : Fixed bug in LUN and RAID Group checks, they were not triggering
#			correctly on the warning and critical thresholds. Updated the help
#			to explain how the warning and critical thresholds are triggered as
#			the existing help was not very clear.
#			
# Version : 2013-03-09
# Date    : March 9th 2013
# Notes   : Plugin updated to incorporate new functionality of using a credentials
#			file instead of supplying a username and password. This code was 
#			supplied by Uwe Kirbach. Fixed a bug that was caused by older versions
#			of perl and the use of switch statements. Changed these switch
#			statements to if elsif statements to allow plugin to run on older
#			versions of perl.
#
# Version : 2013-12-19
# Date    : December 19th 2013
# Notes   : Add an option to set min spare disk expected (--minspare <COUNT>).
#
# Version : 2014-05-06
# Date    : May 6th 2014
# Notes   : Added a check to get the inlet air temperature as a nagios perf
#			metric (Contributed by Max Vernimmen from www.comparegroup.eu).
#			Fixed duplicate port bug when checking just one port. Can now check
#			several specific ports at one time like --port 1,3. (Port fixes
#			contributed by Stanislav German-Evtushenko).
#			Added a check for reporting on Storage Pools (requested and tested by
#			Vitaly Burshteyn, tested by Stanislav German-Evtushenko).
#
#
# Version : 2015-03-24
# Author  : Alexandre Rigaud <arigaud.prosodie.cap(AT)free.fr>
# Date    : March 24th 2015
# Notes   : Added a function to check exit value of commands (check_for_errors was useless).
#			Added debug option to displaying navicli return.
#			Added output option (nagios states, one line stdout for faults only)
#			Added Timeout option, default is 10 sec.

You can apply it to your programs, too.\n";

Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for them if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs, and that you know you can do these things.\n";

Therefore, we have designed this version of the GPL to prohibit the practice for those products.

For example, if you agree to terms that obligate you to collect a royalty for further conveying from those to whom you convey the Program, the only way you could satisfy both those terms and this License would be to refrain entirely from conveying the Program.\n";

=head1 NAME

check_emc_clariion.pl - Checks EMC SAN devices for NAGIOS.


=head1 USAGE:

=head2 Help:

check_emc_clariion.pl --help | more

=head2 Non-Secure:

check_emc_clariion.pl -H <host> -t <checktype>

=head2 Secure:

check_emc_clariion.pl -H <host> -u <user> -p <password> -t <checktype>

check_emc_clariion.pl -H <host> --secfilepath <secfilepath> -t <checktype>

=head2 Non-Secure vs Secure:

The newer versions of Navisphere Cli do NOT come with the Navicli command (Non-Secure) and hence you will need to provide -u and -p options so the Naviseccli can be used (Secure). Alternatively the --secfilepath option allows you to use a directory that has the security credentials encrypted in some files.

=head1 DESCRIPTION

B<check_emc_clariion.pl> receives the data from the emc devices via Navicli or Naviseccli if user and password are provided.


=head1 OPTIONS

=over 8

=item B<-h>

Display this helpmessage.

=item B<-H>

The hostname or ipaddress of the emc storage processor device.

=item B<-u>

The user used to connect to the emc storage processor device with Naviseccli.
You must use this option with -password !

=item B<-p>

The password of the user used to connect to the emc storage processor device with Naviseccli.

=item B<--secfilepath>

The path to the security files used to connect to the emc storage processor device with Naviseccli. You will need to make a directory first to store the files, and then run a command to create the security files in this directory.

The following example will create the directory /usr/local/nagios/libexec/check_emc_clariion_security_files for storing the security files.

You will need to change the username and password to match the credentials you use to connect to the emc storage processor.

Run these commands to create the security files:

  mkdir /usr/local/nagios/libexec/check_emc_clariion_security_files

  /opt/Navisphere/bin/naviseccli -secfilepath /usr/local/nagios/libexec/check_emc_clariion_security_files -User readonly -Password AStrongPassword -Scope 0 -AddUserSecurity

=item B<--debug>

Debug mode. display navicli return errors

=item B<-T>

Integer between 3 and 1800, indicating seconds to wait for response, default to 10

=item B<--state>

Prefix alerts with the service state

=item B<--lineout>

Force one line stdout faults only

=item B<-t>
