apphbd - Application Heartbeat Monitor for High-Availability Linux
apphbd [ -srkdh ] [ -c configure file ]
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 watchdog timer to monitor itself.
apphbd extends its functionality by using plugins. Currently a plugin
recmgr is implemented to notify Recovery Manager daemon if some events
(specified in apphb_notify.h) happen (e.g. an application fails to
The Recovery Manager daemon recoverymgrd receives notification from
recmgr plugin, then it tries to execute recovery scripts as configured.
See recoverymgrd default configure file recoverymgrd.conf for detail.
recoverymgrd registers itself with apphbd as a client application.
apphbd should be started first with plugin recmgr loaded. Then
configure and start recoverymgrd.
