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.
