Which of the following is a valid method to stop monitoring data processing on a cluster node?

The correct approach to stop monitoring data processing on a cluster node is to expand the cluster node and click on Configure. This method allows you to directly access specific settings related to that node, which can include disabling monitoring features without impacting the entire cluster.

This option provides a targeted and precise way to manage the monitoring capabilities of individual nodes within a cluster setup, enabling changes to be made without the need for broader adjustments that might affect operational continuity. The ability to configure settings for each node is paramount in ensuring that performance and monitoring can be tailored based on the requirements of different components of a distributed application.

The other options present less suitable alternatives. Using the system command line may not provide the necessary granularity for stopping monitoring data processing and instead may involve more complex commands that could inadvertently affect other functionalities. Changing network settings does not inherently stop monitoring; it may instead disrupt connectivity without addressing the monitoring process itself. Restarting the entire cluster is a heavy-handed approach that affects all nodes simultaneously and can cause unnecessary downtime for services that are not related to the data processing that one wishes to halt.
