  37 <p><code class="module"><a href="../mod/mod_watchdog.html">mod_watchdog</a></code> defines programmatic hooks for other modules to
  38 periodically run tasks.  These modules can register handlers for
  39 <code class="module"><a href="../mod/mod_watchdog.html">mod_watchdog</a></code> hooks.  Currently, the following modules in the
  40 Apache distribution use this functionality:</p>
  41 <ul>
  42 <li><code class="module"><a href="../mod/mod_heartbeat.html">mod_heartbeat</a></code></li>
  43 <li><code class="module"><a href="../mod/mod_heartmonitor.html">mod_heartmonitor</a></code></li>
  44 </ul>
  45 <div class="warning">
  46 To allow a module to use <code class="module"><a href="../mod/mod_watchdog.html">mod_watchdog</a></code> functionality,
  47 <code class="module"><a href="../mod/mod_watchdog.html">mod_watchdog</a></code> itself must be statically linked to the server
  48 core or, if a dynamic module, be loaded before the calling module.
