+# Please be aware of the following:
+#1. If the network between web, collector, and the agents are not stable, it is advisable not to use this feature.
+#2. We recommend using the cluster.web.tcp.port option. However, in cases where the collector is unable to establish connection to the web, you may reverse this and make the web establish connection to the collector.
