+    The metric will be increased if a cluster-internal connection to a
+    Coordinator cannot be established within 10 seconds. In this case the
+    instance will also log a warning.

+    If this metric keeps increasing permanently or for longer periods, there
+    are likely network connectivity issues or misconfigurations, which can
+    prevent the instance from connecting to every Coordinator in the cluster
+    (potentially connecting to itself). In this case it is advised to check
+    the connectivity manually, and ensure that the instance can make connections
+    to all Coordinators, potentially including itself.
+  
+    If there are temporary network glitches or instance restarts, this metric
+    can also increase. But increases should stop once the network has stabilized
+    and/or instances have restarted successfully.
