=head1 NAME
file_age - Monitors the age of files.
=head1 CONFIGURATION
Since there is no way for the plugin to guess which files you want monitored, you're going to have to set each file up separately. Put the following in a file in your plugin-conf.d directory.
[file_age]
user root # May not be necessary, depending on which files you want monitored.
env.file1_path /var/log/syslog # Mandatory, complete path to file.
env.file1_label System syslog # Optional label if you don't want the file name to be displayed.
env.file1_warning 86400 # Optional warning level. Measured in seconds. 86400 is one day of seconds.
env.file1_critical 864000 # Optional critical level. Measured in seconds.
Continue with file2, file3, etc...
Here, have some seconds:
3600 One hour
7300 Two hours
10800 Three hours
21600 Six hours
43200 Twelve hours
86400 One day
172800 Two days
259200 Three days
604800 One week
