NAME

       apphbd - Application Heartbeat Monitor for High-Availability Linux

SYNOPSIS

       apphbd [-srkdh] [-c file]

DESCRIPTION

           Warning
           apphbd is deprecated; its use is strongly discouraged. The functionality provided by
           apphbd has been replaced by resource-level monitoring in Pacemaker.

       /usr/libexec/heartbeat/apphbd is a basic application heartbeat monitor daemon for
       Linux-HA. A group of Application Heartbeat APIs are defined for this heartbeat monitoring
       service. Applications may register with the daemon in order to be monitored. If an
       application fails to send a heartbeat within the specified interval, the daemon will log
       an event.

       apphbd may use a watchdog timer to monitor itself.

       apphbd extends its functionality by using plugins. A plugin, recmgr notifies the recovery
       manager daemon if certain events occur (e.g. an application fails to heartbeat).

       The Recovery Manager daemon (/usr/libexec/heartbeat/recoverymgrd) receives notification
       from the recmgr plugin, then it tries to execute recovery scripts as configured. See the
       recoverymgrd default configuration file, recoverymgrd.conf for details.

       recoverymgrd registers itself with apphbd as a client application.  apphbd should be
       started first with the recmgr plugin loaded. Then, recoverymgrd should be configured and
       started

OPTIONS

       The following options are supported:

       -s
           Show the status of apphbd, running or stopped.

       -k
           Stop (kill) the daemon.

       -r
           Restart the daemon.  apphbd will reload its configuration file when restarted.

       -d level
           Set the debug level.

       -h
           Show a brief usage message.

       -c file
           Set an alternate configuration file. The default configuration file is ./apphbd.cf.
           For details on the file format and supported options, refer to the example apphbd.cf
           file found in the documentation directory.

FILES

       •   /run/apphbd.pid – default PID file

       •   apphbd.cf – Default configuration file for apphbd.  apphbd searches the file in its
           working directory.

       •   recoverymgrd.conf – default configuration file for recoverymgrd. recoverymgrd searches
           the file in its working directory. An alternative configuration file may be specified
