The correct item to select is Process ID. In Falcon investigations, a Process Timeline requires the sensor-specific process identifier, not merely the operating system PID. The OS PID can be reused over time and is not sufficiently unique for reliable historical telemetry correlation. The Falcon Process ID maps to the process record used by the platform to retrieve process-related events such as file writes, network connections, registry activity, DNS requests, and child process creation. Selecting the command line may provide useful context, but it does not pivot directly into the process timeline. Selecting PID is less precise because it refers to the local operating system process identifier. For accurate process-scoped investigation, the Process ID is the correct pivot point.
