Hello Team,

When I am bootstrapping/restarting a Cassandra Node, there is a delay
between gossip settle and port opening. Can someone please explain me where
this delay is configured and can this be changed? I don't see any
information in the logs

In my case if you see there is  a ~3 minutes delay and this increases if I
increase the #of tables and #of nodes and DC.

Also during this 3 minutes delay, I am losing all my metrics from the C*
nodes(basically the metrics are not returned within 10s).

Can someone please help me understand the delay here?

Cassandra Version: 3.11.3
Metrics: Using telegraf to collect metrics.
