  39 <p><code class="module"><a href="../mod/mod_watchdog.html">mod_watchdog</a></code> defines programmatic hooks for other modules to
  40 periodically run tasks.  These modules can register handlers for
  41 <code class="module"><a href="../mod/mod_watchdog.html">mod_watchdog</a></code> hooks.  Currently, the following modules in the
  42 Apache distribution use this functionality:</p>
  43 <ul>
  44 <li><code class="module"><a href="../mod/mod_heartbeat.html">mod_heartbeat</a></code></li>
  45 <li><code class="module"><a href="../mod/mod_heartmonitor.html">mod_heartmonitor</a></code></li>

  48 To allow a module to use <code class="module"><a href="../mod/mod_watchdog.html">mod_watchdog</a></code> functionality,
  49 <code class="module"><a href="../mod/mod_watchdog.html">mod_watchdog</a></code> itself must be statically linked to the server
  50 core or, if a dynamic module, be loaded before the calling module.
