Apache Module mod_watchdog

Description:	provides infrastructure for other modules to periodically run tasks
Status:	Base
Module Identifier:	watchdog_module
Source File:	mod_watchdog.c
Compatibility:	Available in Apache 2.3 and later

Summary

mod_watchdog defines programmatic hooks for other modules to periodically run tasks. These modules can register handlers for mod_watchdog hooks. Currently, the following modules in the Apache distribution use this functionality:

• mod_heartbeat
• mod_heartmonitor

To allow a module to use mod_watchdog functionality, mod_watchdog itself must be statically linked to the server core or, if a dynamic module, be loaded before the calling module.
