Reading Nagios Alerts

[Robert Wolfe]

The following link has the answer you need:

http://support.nagios.com/knowledgebase/faqs/index.php?option=com_content&view=article&id=52&catid=35&faq_id=70&expand=false&showdesc=true

But, I'll post it here as well:

To quote:

-----8<-----
#!/usr/bin/perl
# nagios-log-print
# taken from the faqs section FAQID: F0070 on the www.nagios.org website
#

if (!@ARGV[0]) {
    print "Usage: {jumi [knowledge-based/faq/viewfaq.php]} <logfile name>\n";
    print "\n";
    print "prints the specified Nagios-logfile with timestamps\n";
    print "converted to human readable time\n";
    exit 1;
}

open(LOG, at ARGV[0]) || die "no Nagios log file named >>>>>>@ARGV[0]<<<<<<";
while (<LOG>) {
    ($part1, $part2) = split(/\s+/, $_, 2);
    $part1 =~ s/\[//;
    $part1 =~ s/\]//;
    print "[", scalar localtime($part1), "]\;$part2\n";
};
close(LOG);


Alternatively, if you want to display the log from the command line use;

perl -pe 's/(\d+)/localtime(jumi)/e' nagios.log

The nagios log files have different time stamps. How can this be converted to the normal time stamp? Can nagios config be changed to output the normal time stamp on the log files?

Thanks!
