| check_failed_logins_rh.sh | check_failed_logins_rh.sh |
This plugin is ment to run in the monitoring target host, so you will need another plugin, like NRPE, installed and configured in your environment.
Example usage:
check_failed_logins.sh -w 5 -c 10
This will check for failed login attempts and return a warning when 5 to 9 attempts fail and a critical when 10 or more attempts fail.
SETUP (with NRPE, with other plugin should be a similar process):
1.- Copy the plugin to the RedHat server you want to monitor.
/usr/lib64/nagios/plugins/check_failed_logins_rh.sh
2.- Define an entry in nrpe.cfg:
command[check_failed_logins]=/usr/lib64/nagios/plugins/check_failed_logins_rh.sh -w 5 -c 10 2>&1
3.- Restart NRPE service.
4.- Create a command in nagios:
define command {
command_name check_failed_logins_rh
command_line $USER1$/check_failed_logins_rh.sh -w $ARG1$ -c $ARG2$
}
Any suggestions will be appreciated.
