The "Analytics" tab in the Juniper Apstra UI is the central location for all operational telemetry and time-series data. It contains pre-defined dashboards and probes for monitoring various aspects of the network's health and performance. For capacity planning, an operator would navigate to this tab to find historical and real-time data on metrics such as link utilization, which are collected and visualized by Apstra's analytics engine.

A: The "Active" tab shows the current deployed topology and its real-time state, not historical time-series information for trend analysis.

B: The "Staged" tab is used for designing and modifying the blueprint's intent before deployment; it contains no operational data.

D: The main "Dashboard" provides a high-level, multi-blueprint overview, while detailed time-series data for a specific blueprint is found within its "Analytics" tab.
