Hi @ugurdemirezen,

# Post Analysis

QGC saves telemetry logs, which you can configure a bit in the [Application Settings](https://www.ardusub.com/reference/qgroundcontrol/application-settings-view.html#telemetry-logs) page. By default they’re saved in your `/Documents/QGroundControl/Telemetry/` folder, assuming you haven’t changed the Application Load/Save Path setting.

QGC’s default CSV output option may be useful, but

# While Operating

If you’re interested in getting data in real-time (rather than analysing a telemetry log file afterwards) then you can either

- set up an extra MAVLink endpoint via the [Mavproxy page](https://www.ardusub.com/reference/companion/mavproxy.html) of the Companion web interface (e.g. add `--udpout 192.168.2.1:14560`), and connect to it (e.g. using [Pymavlink](https://www.ardusub.com/developers/pymavlink.html#run-pymavlink-on-the-surface-computer)), or
- connect to the [mavlink2rest](https://github.com/patrickelectric/mavlink2rest) output at [http://192.168.2.2:4777](http://192.168.2.2:4777) with a [websocket client connection](https://github.com/patrickelectric/mavlink2rest/blob/master/examples/websocket_client.py)
