+# Sample NRPE Config File 
+# Written by: Ethan Galstad (nagios@nagios.org)
+# 
+# Last Modified: 11-23-2007
+#
+# NOTES:
+# This is a sample configuration file for the NRPE daemon.  It needs to be
+# located on the remote host that is running the NRPE daemon, not the host
+# from which the check_nrpe client is being executed.

+# supported.
+#
+# Note: The daemon only does rudimentary checking of the client's IP

+
+# COMMAND PREFIX
+# This option allows you to prefix all commands with a user-defined string.
+# A space is automatically added between the specified prefix string and the
+# command line from the command definition.
+#
+# *** THIS EXAMPLE MAY POSE A POTENTIAL SECURITY RISK, SO USE WITH CAUTION! ***
+# Usage scenario: 
+# Execute restricted commmands using sudo.  For this to work, you need to add
+# the nagios user to your /etc/sudoers.  An example entry for alllowing 
+# execution of the plugins from might be:
+#
+# nagios          ALL=(ALL) NOPASSWD: /usr/lib/nagios/plugins/
+#
+# This lets the nagios user run all commands in that directory (and only them)
+# without asking for a password.  If you do this, make sure you don't give
+# random users write access to that directory or its contents!
+
+# command_prefix=/usr/bin/sudo

+
+# DEBUGGING OPTION
+# This option determines whether or not debugging messages are logged to the
+# syslog facility.
+# Values: 0=debugging off, 1=debugging on
+
+debug=0
+
+
+
+# COMMAND TIMEOUT
+# This specifies the maximum number of seconds that the NRPE daemon will
+# allow plugins to finish executing before killing them off.
+
+command_timeout=60
+
+
+
+# CONNECTION TIMEOUT
+# This specifies the maximum number of seconds that the NRPE daemon will
+# wait for a connection to be established before exiting. This is sometimes
+# seen where a network problem stops the SSL being established even though
+# all network sessions are connected. This causes the nrpe daemons to
+# accumulate, eating system resources. Do not set this too low.
+
+connection_timeout=300
+
+
+
+# WEEK RANDOM SEED OPTION
+# This directive allows you to use SSL even if your system does not have
+# a /dev/random or /dev/urandom (on purpose or because the necessary patches
+# were not applied). The random number generator will be seeded from a file
+# which is either a file pointed to by the environment valiable $RANDFILE
+# or $HOME/.rnd. If neither exists, the pseudo random number generator will
+# be initialized and a warning will be issued.
+# Values: 0=only seed from /dev/[u]random, 1=also seed from weak randomness
+
+#allow_weak_random_seed=1
+
+
+
+# INCLUDE CONFIG FILE
+# This directive allows you to include definitions from an external config file.
+
+#include=<somefile.cfg>
+
+
+
+# INCLUDE CONFIG DIRECTORY
+# This directive allows you to include definitions from config files (with a
+# .cfg extension) in one or more directories (with recursion).
+
+#include_dir=<somedirectory>
+#include_dir=<someotherdirectory>
+
+
+
+# COMMAND DEFINITIONS
+# Command definitions that this daemon will run.  Definitions
+# are in the following format:
+#
+# command[<command_name>]=<command_line>
+#
+# When the daemon receives a request to return the results of <command_name>
+# it will execute the command specified by the <command_line> argument.
+#
+# Unlike Nagios, the command line cannot contain macros - it must be
+# typed exactly as it should be executed.
+#
+# Note: Any plugins that are used in the command lines must reside
+# on the machine that this daemon is running on!  The examples below
+# assume that you have plugins installed in a /usr/local/nagios/libexec
+# directory.  Also note that you will have to modify the definitions below
+# to match the argument format the plugins expect.  Remember, these are
+# examples only!

+#
+# ===================== INFORMATION ABOUT THIS PLUGIN =========================
+#
+#  This plugin returns uptime of the system returning data in text (readable)
+#  format as well as in minutes for performance graphing. The plugin can either
+#  run on local system unix system (that supports standard 'uptime' command
+#  or check remote system by SNMP. The plugin can report one CRITICAL or
+#  WARNING alert if system has been rebooted since last check.
+#
+# ======================  SETUP AND PLUGIN USE NOTES  =========================
+#
+#  The plugin can either retrieve information from local system (when you
+#  run it through check_nrpe for example) or by SNMP from remote system.
+#
+#  On local system it will execute standard unix 'uptime' and 'uname -a'.
+#
+#  On a remote system it'll retrieve data from sysSystem for system type
+#  and use that to decide if further data should be retrieved from 
+#    sysUptime (OID 1.3.6.1.2.1.1.3.0) for windows or 
+#    hostUptime (OID 1.3.6.1.2.1.25.1.1.0) for unix system or
+#    snmpEngineTime (OID 1.3.6.1.6.3.10.2.1.3) for cisco switches
+#
+#  For information on available options please execute it with --help i.e:
+#    check_uptime.pl --help
+#
+#  As I dont have time for extensive documentation below is all very brief:
+#
+#  1. You can also specify warning and critical thresholds which will
+#     give warning or critical alert if system has been up for lees then
+#     specified number of minutes. Example: 
+#        check_uptime.pl -w 5
+#     Will give warning alert if system has been up for less then 5 minutes
+#
+#  2. For performance data results you can use '-f' option which will give
+#     total number of minutes the system has been up.
+#
+#  3. A special case is use of performance to feed data from previous run
+#     back into the plugin. This is used to cache results about what type
+#     of system it is (you can also directly specify this with -T option)
+#     and also means -w and -c threshold values are ignored and instead
+#     plugin will issue ONE alert (warning or critical) if system uptime
+#     changes from highier value to lower
+#
+# ============================ EXAMPLES =======================================
+#
+# 1. Local server (use with NRPE or on nagios host), warning on < 5 minutes:
+#
+# define command {
+#        command_name check_uptime
+#        command_line $USER1$/check_uptime.pl -f -w 5
+# }
+# 
+# 2. Local server (use with NRPE or on nagios host), 
+#    one critical alert on reboot:
+#
+# define command {
+#        command_name check_uptime
+#        command_line $USER1$/check_uptime.pl -f -c -P "SERVICEPERFDATA$"
+# }
+#
+# 3. Remote server SNMP v2, one warning alert on reboot,
+#    autodetect and cache type of server:
+#
+# define command {
+#        command_name check_snmp_uptime_v2
+#        command_line $USER1$/check_uptime.pl -2 -f -w -H $HOSTADDRESS$ -C $_HOSTSNMP_COMMUNITY$ -P "$SERVICEPERFDATA$"
+# }
+#
+# 4. Remote server SNMP v3, rest as above
+#
+#define command {
+#        command_name check_snmp_uptime_v3
+#        command_line $USER1$/check_uptime.pl -f -w -H $HOSTADDRESS$ -l $_HOSTSNMP_V3_USER$ -x $_HOSTSNMP_V3_AUTH$ -X $_HOSTSNMP_V3_PRIV$ -L sha,aes -P "$SERVICEPERFDATA$"
+# }
+# 
+# 5. Example of service definition using above
+#
+# define service{
+#      use				std-service
+#      hostgroup_name			all_snmp_hosts
+#      service_description		SNMP Uptime
+#      max_check_attempts               1
+#      check_command			check_snmp_uptime
+# }
+#
+# 6. And this is optional dependency definition for above which makes
+#    every SNMP service (service beloning to SNMP servicegroup) on
+#    same host dependent on this SNMP Uptime check. Then if SNMP
+#    daemon goes down you only receive one alert
+#
+# define servicedependency{
+#        service_description SNMP Uptime
+#        dependent_servicegroup_name snmp
+# }
+#
+# ============================= VERSION HISTORY ==============================
+#
+# 0.1 - sometime 2006 : Simple script for tracking local system uptime
+# 0.2 - sometime 2008 : Update to get uptime by SNMP, its now alike my other plugins 
+# 0.3 -  Nov 14, 2009 : Added getting system info line and using that to decide
+#		        format of uptime line and how to process it. Added support
+#			for getting uptime with SNMP from windows systems.
+#			Added documentation header alike my other plugins.
+#			Planned to release it to public, but forgot.
+# 0.4  - Dec 19, 2011 : Update to support SNMP v3, released to public
+# 0.41 - Jan 13, 2012 : Added bug fix by Rom_UA posted as comment on Nagios Exchange
+#			Added version history you're reading right now.
+# 0.42 - Feb 13, 2012 : Bug fix to not report WARNING if uptime is not correct output
+# 0.5  - Feb 29, 2012 : Added support for "netswitch" engine type that retrieves
+#		        snmpEngineTime. Added proper support for sysUpTime interpreting
+#			it as 1/100s of a second and converting to days,hours,minutes
+#			Changed internal processing structure, now reported uptime
+#			info text is based on uptime_minutes and not separate.
+# 0.51 - Jun 05, 2012 : Bug fixed for case when when snmp system info is < 3 words.
+# 0.52 - Jun 19, 2012 : For switches if snmpEngineTime OID is not available,
+#		        the plugin will revert back to checking hostUptime and
+#			then sysUptime. Entire logic has in fact been changed
+#			to support trying more than just two OIDs. Also added
+#			support to specify filename to '-v' option for debug
+#		        output to go to instead of console and for '--debug'
+#			option as an alias to '--verbose'.
+# 
+# TODO:
+#   0) Add '--extra-opts' to allow to read options from a file as specified
+#      at http://nagiosplugins.org/extra-opts. This is TODO for all my plugins
+#   1) Add support for ">", "<" and other threshold qualifiers
+#      as done in check_snmp_temperature.pl or check_mysqld.pl
+#   2) Support for more types, in particular network equipment such as cisco: [DONE]
+#      	     sysUpTime is a 32-bit counter in 1/100 of a second, it rolls over after 496 days
+#            snmpEngineTime (.1.3.6.1.6.3.10.2.1.3) returns the uptime in seconds and will not
+#            roll over, however some cisco switches (29xx) are buggy and it gets reset too.
+#            Routers running 12.0(3)T or higher can use the snmpEngineTime object from
+#            the SNMP-FRAMEWORK-MIB.  This keeps track of seconds since SNMP engine started.
+#   3) Add threshold into perfout as ';warn;crit'

+Debug & Console Options:
+ -v, --verbose[=FILENAME], --debug[=FILENAME]
+   print extra debugging information.
+   if filename is specified instead of STDOUT the debug data is written to that file
+ -h, --help
+   print this help message
+ -V, --version
+   prints version number
+
+Standard Options:
+ -T, --type=auto|local|unix-host|unis-sys|windows|netswitch
+   Type of system:
+     local           : localhost (executes 'uptime' command), default if no -C or -l
+     unix-host       : SNMP check from hostUptime ($oid_hostUptime) OID
+     unix-sys        : SNMP check from sysUptime ($oid_sysUptime) OID
+     win | windows   : SNMP check from sysUptime ($oid_sysUptime) OID
+     net | netswitch : SNMP check from snmpEngineTime ($oid_engineTime) OID
+     auto            : Autodetect what system by checking sysSystem OID first, default
+ -w, --warning[=minutes]
+   Report nagios WARNING alert if system has been up for less then specified
+   number of minutes. If no minutes are specified but previous preformance
+   data is fed back with -P option then alert is sent ONLY ONCE when
+   uptime changes from greater value to smaller
+ -c, --critical[=minutes]
+   Report nagios CRITICAL alert if system has been up for less then
+   specified number of minutes or ONE ALERT if -P option is used and
+   system's previous uptime is larger then current on
+ -f, --perfparse
+   Perfparse compatible output 
+ -P, --prev_perfdata
+   Previous performance data (normally put '-P \$SERVICEPERFDATA\$' in
+   nagios command definition). This is recommended if you dont specify
+   type of system with -T so that previously checked type of system info
+   is reused. This is also used to decide on warning/critical condition
+   if number of seconds is not specified with -w or -c.
+ --label=[string]
+   Optional custom label before results prefixed to results
+ -t, --timeout=INTEGER
+   timeout for SNMP in seconds (Default: 15)
+ 
+SNMP Access Options:
+ -H, --hostname=HOST
+   name or IP address of host to check (if not localhost)
+ -C, --community=COMMUNITY NAME
+   community name for the SNMP agent (used with v1 or v2c protocols)
+ -2, --v2c
+   use snmp v2c (can not be used with -l, -x)
+ -l, --login=LOGIN ; -x, --passwd=PASSWD
+   Login and auth password for snmpv3 authentication 
+   If no priv password exists, implies AuthNoPriv 
+ -X, --privpass=PASSWD
+   Priv password for snmpv3 (AuthPriv protocol)
+ -L, --protocols=<authproto>,<privproto>
+   <authproto> : Authentication protocol (md5|sha : default md5)
+   <privproto> : Priv protocols (des|aes : default des) 
+ -p, --port=PORT
