NAME

       watchdog.conf - configuration file for the watchdog daemon

DESCRIPTION

       This  file  carries  all configuration options for the Linux watchdog daemon.  Each option
       has to be written on a line for itself. Comments  start  with  '#'.   Blanks  are  ignored
       except  after  the '=' sign. An empty text after the '=' sign disables the feature as long
       as that makes sense.

OPTIONS

       interval = <interval>
              Set the interval between two writes to the  watchdog  device.  The  kernel  drivers
              expects  a  write  command  every  minute.  Otherwise  the system will be rebooted.
              Default value is 1 second. An interval of more than a minute can only be used  with
              the -f command-line option.

       logtick = <logtick>
              If  you  enable verbose logging, a message is written into the syslog or a logfile.
              While this is nice, it is not necessary to get a message  every  10  seconds  which
              really  fills  up  disk  and  needs CPU. logtick allows adjustment of the number of
              intervals skipped before a log message is written. If you  use  logtick  =  60  and
              interval  =  10, only every 10 minutes (600 seconds) a message is written. This may
              make the exact time of a crash harder to find but greatly reduces  disk  usage  and
              administrator  nerves if you're looking for a particular syslog entry in between of
              watchdog messages.

       max-load-1 = <load1>
              Set the maximal allowed load average for a 1 minute span. Once this load average is
              reached  the  system  is  rebooted. Default value is 0. That means the load average
              check is disabled. Be careful not to this parameter too low. To set  a  value  less
              then the predefined minimal value of 2, you have to use the -f commandline option.

       max-load-5 = <load5>
              Set the maximal allowed load average for a 5 minute span. Once this load average is
              reached the system is rebooted. Default value is 3/4*max-load-1.  Be careful not to
              this parameter too low. To set a value less then the predefined minimal value of 2,
              you have to use the -f commandline option.

       max-load-15 = <load15>
              Set the maximal allowed load average for a 15 minute span. Once this  load  average
              is reached the system is rebooted. Default value is 1/2*max-load-1.  Be careful not
              to this parameter too low. To set a value less then the predefined minimal value of
              2, you have to use the -f commandline option.

       min-memory = <minpage>
              Set  the  minimal amount of virtual memory that has to stay free. Note that this is
              in pages. Default value is 0 pages which means this test is disabled. The page size
              is taken from the system include files.

       max-temperature = <temp>
              Set the maximal allowed temperature. Once this temperature is reached the system is
              halted. Default value is 120. There is no unit conversion, so make sure you use the
              same  unit  as  your  hardware.  Watchdog  will issue warnings once the temperature
              increases 90%, 95% and 98% of this temperature.

       watchdog-device = <device>
              Set the watchdog device name. Default is to disable keep alive support.

       watchdog-timeout = <timeout>
              Set the watchdog device timeout during startup.  If not set, the default is driver-
              dependent.

       temperature-device = <temp-dev>
              Set the temperature device name. Default is to disable temperature checking.

       file = <filename>
              Set  file  name  for  file  mode.  This option can be given as often as you like to
              check several files.

       change = <mtime>
              Set the change interval time for file mode. This  options  always  belongs  to  the
              active filename, that is when finding a 'change =' line watchdog assumes it belongs
              to the most recently read 'file =' line.  They don't neccessarily  have  to  follow
              each  other  directly.  But you cannot specify a 'change =' before a 'file ='.  The
              default is to only stat the file and don't look for changes.  Using this feature to
              monitor  changes  in  /var/log/messages  might  require  some special syslog daemon
              configuration, e.g. rsyslog needs "$ActionWriteAllMarkMessages on"  to  be  set  to
              make sure the marks are written no matter what.

       pidfile = <pidfilename>
              Set  pidfile  name  for server test mode.  This option can be given as often as you
              like to check several servers.

       ping = <ip-addr>
              Set IP address for ping mode.  This option can be used  more  than  once  to  check
              different connections.

       interface = <if-name>
              Set  interface  name  for  network mode.  This option can be used more than once to
              check different interfaces.

       test-binary = <testbin>
              Execute the given binary to do some user defined tests.

       test-timeout = <timeout in seconds>
              User defined tests may only run for <timeout> seconds. Set to 0 for unlimited.

       repair-binary = <repbin>
              Execute the given binary in case of a problem instead of shutting down the system.

       repair-timeout = <timeout in seconds>
              repair command may only run for <timeout> seconds. Set to 0 for unlimited.

       admin = <mail-address>
              Email address to send admin mail to. That  is,  who  shall  be  notified  that  the
              machine  is  being  halted  or  rebooted. Default is 'root'. If you want to disable
              notification via email just set admin to en empty string.

       realtime = <yes|no>
              If set to yes watchdog will lock itself into memory so it is never swapped out.

       priority = <schedule priority>
              Set the schedule priority for realtime mode.

       test-directory = <test directory>
              Set the directory to run user test/repair scripts.   Default  is  '/etc/watchdog.d'
              See the Test Directory section in watchdog(8) for more information.

       log-dir = <log directory>
              Set  the  log  directory  to  capture  the  standard output and standard error from
              repair-binary and test-binary execution. Default is '/var/log/watchdog'.
