<h3>Sommaire</h3>

    <p><code>lbmethod=heartbeat</code> utilise les services du module
    <code class="module"><a href="../mod/mod_heartmonitor.html">mod_heartmonitor</a></code> pour r&eacute;partir la charge entre les
    serveurs d'origine qui fournissent des donn&eacute;es heartbeat via le
    module <code class="module"><a href="../mod/mod_heartbeat.html">mod_heartbeat</a></code>.</p>

<p>Son algorithme de r&eacute;partition de charge favorise les serveurs dont la
capacit&eacute; de traitement moyenne r&eacute;partie dans le temps est la plus
importante, mais il ne s&eacute;lectionne pas forc&eacute;ment le serveur qui pr&eacute;sente
la disponibilit&eacute; instantan&eacute;e la plus importante. Les serveurs qui ne
poss&egrave;dent aucun client actif sont p&eacute;nalis&eacute;s, car ils sont consid&eacute;r&eacute;s
comme non enti&egrave;rement initialis&eacute;s.</p>
