What function does TabMon serve in Tableau Server?

TabMon serves as a performance monitoring tool designed specifically for Tableau Server environments. It focuses on analyzing system performance by collecting and presenting data about the server's operational state. Through the utilization of various metrics, such as CPU usage, memory utilization, and request handling times, TabMon helps administrators gain insights into how well the Tableau Server is performing. This data can then be used to diagnose potential issues, optimize performance, and ensure that resources are being utilized effectively.

The other options, while related to functionalities within the Tableau ecosystem or data visualization in general, do not accurately describe TabMon's capabilities. For example, the function of connecting to external APIs or creating dashboards does not align with TabMon’s role. Instead, its specific purpose revolves solely around monitoring and enhancing performance for the Tableau Server, making it a critical tool for administrators who need to maintain optimal operational conditions.
