<h3>Sommaire</h3>

<p>
<code class="module"><a href="../mod/mod_heartmonitor.html">mod_heartmonitor</a></code> interpr&egrave;te les messages d'&eacute;tat g&eacute;n&eacute;r&eacute;s
par les serveurs d'origine pour lesquels <code class="module"><a href="../mod/mod_heartbeat.html">mod_heartbeat</a></code> est activ&eacute; et
fournit ces informations &agrave; <code class="module"><a href="../mod/mod_lbmethod_heartbeat.html">mod_lbmethod_heartbeat</a></code>, 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>Ce module utilise les services de <code class="module"><a href="../mod/mod_slotmem_shm.html">mod_slotmem_shm</a></code>,
lorsqu'il est disponible, au lieu d'un simple fichier texte. Aucune
configuration suppl&eacute;mentaire n'est requise pour utiliser
<code class="module"><a href="../mod/mod_slotmem_shm.html">mod_slotmem_shm</a></code>.</p>

    <div class="warning">
