NAME

apphbd - Application Heartbeat Monitor for High-Availability Linux

apphbd [-srkdh] [-c file]

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 The functionality provided by apphbd has been replaced by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

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.

o apphbd.cf - Default configuration file for apphbd. apphbd searches: the file in its working directory.
o recoverymgrd.conf - default configuration file for recoverymgrd.: recoverymgrd searches the file in its working directory. An
