<h3>Sommaire</h3>

    <p><code class="module"><a href="../mod/mod_heartbeat.html">mod_heartbeat</a></code> envoie à un moniteur
    <code class="module"><a href="../mod/mod_heartmonitor.html">mod_heartmonitor</a></code> des messages multicast l'informant
    du nombre de connexions courantes. En général,
    <code class="module"><a href="../mod/mod_heartmonitor.html">mod_heartmonitor</a></code> est chargé sur un serveur
    mandataire où <code class="module"><a href="../mod/mod_lbmethod_heartbeat.html">mod_lbmethod_heartbeat</a></code> est chargé, ce
    qui permet d'utiliser la <em>lbmethod</em> "heartbeat" au sein des
    directives <code class="directive"><a href="../mod/mod_proxy.html#proxypass">ProxyPass</a></code>.</p>

    <p>
    Le module <code class="module"><a href="../mod/mod_heartbeat.html">mod_heartbeat</a></code> est chargé sur le
    serveur d'origine qui sert les requêtes via le
    serveur mandataire.

<h2><a name="consuming" id="consuming">Utilisation de la sortie de mod_heartbeat</a></h2>
    
  <p>
      Chaque seconde, ce module génère un paquet multicast UDP contenant
      le nombre de threads/processus occupés et en attente. Le paquet
      possède un format ASCII simple similaire aux paramètres de requête
      GET en HTTP.
  </p>

<div class="example"><h3>Exemple de paquet</h3><p><code>
v=1&amp;ready=75&amp;busy=0
</code></p></div>

  <p>
    Les utilisateurs disposeront dans le futur de nouvelles variables en
    plus de busy et ready, et toujours séparées par des '&amp;'.
