<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.
</p>
<div class="warning">
Pour utiliser <code class="module"><a href="../mod/mod_heartbeat.html">mod_heartbeat</a></code>,
<code class="module"><a href="../mod/mod_status.html">mod_status</a></code> et <code class="module"><a href="../mod/mod_watchdog.html">mod_watchdog</a></code>
doivent être soit des modules statiques, soit des modules
dynamiques, et dans ce dernier cas, ils doivent être chargés
avant <code class="module"><a href="../mod/mod_heartbeat.html">mod_heartbeat</a></code>.

<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&ready=75&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 '&'.

<p>La directive <code class="directive">HeartbeatAddress</code> permet de
spécifier l'adresse multicast à laquelle <code class="module"><a href="../mod/mod_heartbeat.html">mod_heartbeat</a></code> va
envoyer ses informations. En général, cette adresse correspond à la
valeur définie par la directive <code class="directive"><a href="../mod/mod_heartmonitor.html#heartbeatlisten">HeartbeatListen</a></code> sur le serveur
mandataire frontal.</p>
