    NAME

    
    
    watchdogd
    
     - watchdog daemon
    
     
    

    SYNOPSIS

    [-d ] [-e cmd ] [-I file ] [-s sleep ] [-t timeout ]  

    DESCRIPTION

    The utility interfaces with the kernel's watchdog facility to ensure that the system is in a working state. If is unable to interface with the kernel over a specific timeout, the kernel will take actions to assist in debugging or restarting the computer.

    If -e cmd is specified, will attempt to execute this command with system(3), and only if the command returns with a zero exit code will the watchdog be reset. If -e cmd is not specified, the daemon will perform a trivial file system check instead.

    The -s sleep argument can be used to control the sleep period between each execution of the check and defaults to one second.

    The -t timeout specifies the desired timeout period in seconds. The default timeout is 16 seconds.

    One possible circumstance which will cause a watchdog timeout is an interrupt storm. If this occurs, will no longer execute and thus the kernel's watchdog routines will take action after a configurable timeout.

    Upon receiving the SIGTERM or SIGINT signals, will first instruct the kernel to no longer perform watchdog checks and then will terminate.

    The utility recognizes the following runtime options:

    -I file
    Write the process ID of the utility in the specified file.
    -d
    Do not fork. When this option is specified, will not fork into the background at startup.
