<h3>Sommaire</h3>
<p>
<code class="module"><a href="../mod/mod_heartmonitor.html">mod_heartmonitor</a></code> interprte les messages d'tat gnrs
par les serveurs d'origine pour lesquels <code class="module"><a href="../mod/mod_heartbeat.html">mod_heartbeat</a></code> est activ et
fournit ces informations <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 supplmentaire n'est requise pour utiliser
<code class="module"><a href="../mod/mod_slotmem_shm.html">mod_slotmem_shm</a></code>.</p>
<div class="warning">
Pour utiliser <code class="module"><a href="../mod/mod_heartmonitor.html">mod_heartmonitor</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 tre soit des modules statiques, soit des modules
dynamiques, et dans ce dernier cas, ils doivent tre chargs
avant <code class="module"><a href="../mod/mod_heartmonitor.html">mod_heartmonitor</a></code>.
