Summary
[mod_watchdog](../mod/mod%5Fwatchdog.html) defines programmatic hooks for other modules to periodically run tasks. These modules can register handlers for[mod_watchdog](../mod/mod%5Fwatchdog.html) hooks. Currently, the following modules in the Apache distribution use this functionality:
[mod_heartbeat](../mod/mod%5Fheartbeat.html)[mod_heartmonitor](../mod/mod%5Fheartmonitor.html)[mod_md](../mod/mod%5Fmd.html)[mod_proxy_hcheck](../mod/mod%5Fproxy%5Fhcheck.html)
To allow a module to use [mod_watchdog](../mod/mod%5Fwatchdog.html) functionality,[mod_watchdog](../mod/mod%5Fwatchdog.html) itself must be statically linked to the server core or, if a dynamic module, be loaded before the calling module.
