<description>provides infrastructure for other modules to periodically run

<summary>
<p><module>mod_watchdog</module> defines programmatic hooks for other modules to
periodically run tasks. These modules can register handlers for
<module>mod_watchdog</module> hooks. Currently, the following modules in the
Apache distribution use this functionality:</p>
<ul>
<li><module>mod_heartbeat</module></li>
<li><module>mod_heartmonitor</module></li>
</ul>
<note type="warning">
To allow a module to use <module>mod_watchdog</module> functionality,
<module>mod_watchdog</module> itself must be statically linked to the server
core or, if a dynamic module, be loaded before the calling module.
