| <h3>Sommaire</h3> |
| |
| <p> |
| <code class="module"><a href="../mod/mod_heartmonitor.html">mod_heartmonitor</a></code> interprète les messages d'état générés |
| par les serveurs d'origine pour lesquels <code class="module"><a href="../mod/mod_heartbeat.html">mod_heartbeat</a></code> est activé et |
| fournit ces informations à <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 supplémentaire 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 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_heartmonitor.html">mod_heartmonitor</a></code>. |
