<h3>Sommaire</h3>
<p>lbmethod=heartbeat utilise les services du module
<code class="module"><a href="../mod/mod_heartmonitor.html">mod_heartmonitor</a></code> pour rpartir la charge entre les
serveurs d'origine qui fournissent des donnes heartbeat via le
module <code class="module"><a href="../mod/mod_heartbeat.html">mod_heartbeat</a></code>.</p>
<p>Son algorithme de rpartition de charge favorise les serveurs dont la
capacit de traitement moyenne rpartie dans le temps est la plus
importante, mais il ne slectionne pas forcment le serveur qui prsente
la disponibilit instantane la plus importante. Les serveurs qui ne
possdent aucun client actif sont pnaliss, car ils sont considrs
comme non entirement initialiss.</p>
