check_daytime

If you need more precise measurements I suggest instead using NTPd but not everyone wants to bother setting it up and on most unix systems setting up time or utime is very easy with protocols supported as part of base inetd services. For more information about using this plugin use '-h' option: # ./check_daytime.pl --help check_daytime plugin for nagios version 0.2 by William Leibzon - william(at)leibzon.org Usage: ./check_daytime.pl -v | -h | -P daytime|daytime-udp|time|time-udp -p -H -w -c -t usec -f This is a nagios plugin that connects to remote host using protocol specified with -P which can be either daytime (port 13) or RRC868 time service (port 37) running on TCP or UDP and then checks that time specified on remote host is no more then seconds different then local time on host executing this plugin. Port numbers (13 or 37) above can optionally be overridden with -p option. If daytime service is used the string returned by remote host should be in the format like '01 JAN 2006 12:01:01 PDT' -v, --verbose print extra debugging information -h, --help print this help message -H, --hostname=HOST (STRING) name or IP address of host to check (required parameter) -P, --protocol=daytime|daytime-udp|time|time-udp protocol used to get remote time (required paramter) note that daytime protocol should give one string like '01 JAN 2006 12:01:01 PDT' (its parsed with Date::Parse str2time) -p, --port=port (INTEGER) This overrides default values set based on '--protocol' parameter which are by default 13 for daytime and 37 for time protocols -w, --warn=variance (INTEGER) If the difference between remote host and localhost is more then equal to this number of seconds then cause WARNING returned to Nagios -c, --critical=variance (INTEGER) If the difference between remote host and localhost is more then equal to this number of seconds then cause CRITICAL error returned to Nagios -t, --timeout=seconds (INTEGER) timeout for network connection (default : 5 seconds) -f, --perfparse Causes time & difference not only in main status line but also as perfparse output -o, --formout=str|usec Time printed as output is a readable time string when 'str' is specified (default) or unix seconds with 1970 (when usec is specified)
