Ping timeout: Time for which the system is waiting for the ping response. With
mobile networks the response time can be quite long (several

SYSTEM – Troubleshooting – Network Debugging – Ping. The first
response typically takes a longer time than the following ones in
GPRS/UMTS networks, the Ping timeout should be set to the longer
time than with the first response.
Ping interval: Time to wait before sending the next probe.
Retry interval (if ping failed): If the first trial fails, ping hosts in this modified interval until the ping
is successful or the maximum number of failed trials is reached.
Max. number of failed trials: The maximum number of failed ping trials until the ping check will
be declared as failed.
Emergency action: Configure the Emergency action which should be taken after the
maximum downtime is reached. Using "reboot" perfoms the system
