# apphbd(8)

Application Heartbeat Monitor for High-Availability Linux

## 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 The functionality provided by **apphbd** has been replaced by resource-level monitoring in Pacemaker.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 on the command line.

• /usr/lib/heartbeat/plugins/AppHBNotification – directory containing plugins for **apphbd**.
