#
# ===================== 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'

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
SNMP port (Default 161)
