To see the files being staged locally for telemetry, navigate to /var/opt/MarkLogic/Stage/Logs. Type tail -f ErrorLog.txt |grep -i telemetry and press return. When telemetry is enabled this will show a running log of the data being that is being collected and uploaded every 5 minutes.

This example shows when data that has been sent to telemetry:

[localhost Logs]$ tail -f ErrorLog.txt |grep -i telemetry
