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 10 seconds. 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.

       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.

       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.

       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.
