What tool provides insights on forwarder activity and throughput every 15 minutes?

The Monitoring Console is the tool specifically designed for monitoring the health and performance of a Splunk deployment, including insights on forwarder activity and throughput. It provides a comprehensive overview of the system's operations, allowing administrators to track various metrics related to data ingestion and forwarder performance.

The Monitoring Console's functionality includes displaying data about the number of events being forwarded, the performance of forwarders, and the overall health of forwarder connections. This information is crucial for maintaining an efficient Splunk environment, as it allows the admin to quickly identify and address issues related to data transmission.

While other tools like Forwarder Management and the Deployment Server have roles in managing forwarders, they do not provide the same level of real-time, periodic insights into forwarder activity and throughput specifically every 15 minutes. The Search Head primarily focuses on data querying and visualization, not on monitoring forwarder performance metrics. The unique role of the Monitoring Console in this context makes it the correct choice for tracking forwarder activity and throughput.
