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 The functionality provided by apphbd has been replaced by resource-level monitoring in Pacemaker.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/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

OPTIONS

The following options are supported:
-s
Show the status of apphbd, running or stopped.
-k

-r

-d level

-h
