Nagios check_file_age mod

Category: Sysadmin / Tag: , ,  / Add Comment

As I don’t think in seconds about time and more like hours days etc. I’ve added this small bit of code to Nagios check_file_age script to display age in days. I’m using this to check PID file age for service that needs daily/weekly restarts.

By default you will get something like this:

FILE_AGE CRITICAL: /var/run/server.pid is 457395 seconds old and 4 bytes

I’m to lazy to calculate this ;)

Find this line in the code:

print "FILE_AGE $result: $opt_f is $age seconds old and $size bytes\n";

and replace it with:

my $days = $age/86400;
$days = sprintf("%.1f", $days);

print "FILE_AGE $result: $opt_f is $age seconds ($days days) old and $size bytes\n";

Now you will get:

FILE_AGE CRITICAL: /var/run/server.pid is 457381 seconds (5.3 days) old and 4 bytes

Much nicer :)
