Which command is used in Cassandra to view gossip information?

cqlsh gossipinfo
nodetool gossipinfo
cassandra gossipinfo
gossip view

The correct answer is: nodetool gossipinfo

In Apache Cassandra, the command used to view gossip information is 'nodetool gossipinfo.' The 'nodetool' utility is a command-line interface that provides various management commands for monitoring and managing Cassandra nodes. The 'gossipinfo' subcommand specifically allows users to retrieve detailed information about the gossip protocol, which is crucial for how nodes in a Cassandra cluster communicate and share state information. Gossip is essential for maintaining the health and status of nodes in a distributed system, providing insights into node health, membership, and data replication. By using 'nodetool gossipinfo,' administrators can gain an understanding of these dynamics and identify potential issues in the cluster, such as unreachable nodes or those that have recently joined or left the cluster. The other options listed do not represent valid commands within the Cassandra environment for viewing gossip information, which solidifies 'nodetool gossipinfo' as the correct choice for this task.
