ZyWALL (ZLD) CLI Reference Guide

The application watchdog has the system restart a process that fails. These are the 

app-watchdog

 

commands. Use the 

configure terminal

 command to enter the configuration mode to be able 

to use these commands.

The following example displays the application watchdog configuration and lists the processes that 
the application watchdog is monitoring.

app-watchdog Commands 

[no] app-watch-dog activate

setting back to the default.
