+#
+# ===================== 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'.
+# 0.521 - Oct 4, 2012 : Small bug in one of regex, see issue #11 on github
+#
+# 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'

+Uploaders: Bernd Zeimetz <bzed at debian.org>
+Description: check_uptime returns uptime of a system
+ in text (readable) format as well as in minutes for performance graphing.
+ The plugin can either run on a local unix system (using 'uptime' command)
+ or check remote system by SNMP. Also it is able to report one CRITICAL
+ or WARNING alert if system has been rebooted since last check.
+Recommends: libnet-snmp-perl
+Version: 1.0.1
