Profiler.enableBinaryLog

Description

Enables the logging of profiling data to a file.

When enabled, the Unity player saves profiling data to the file specified in the Profiler.logFile file. The player automatically assigns the file extension, “.raw” to this log file. You can load this file in the Unity Editor using the Profiler window to view the data.

You must also set Profiler.enabled to true. If the buffer is too small to output the profiler data you will see a message in the debug log "Skipping profile frame. Receiver can not keep up with the amount of data sent". Use Profiler.maxUsedMemory to raise the buffer memory.

Note: In the following example, on the WebGL platform, the log file is outputted to a path like the following: /idbfs/some-hash/profiler.raw. To find this file, use your browser's developer tools. You can also use File.Open with the same path that you used to load the data, and use UnityWebRequest.Post to send it to a web server.

        yield return new WaitForSeconds(5.0f);

        Profiler.enabled = false;
        // It is important to change the log file so it can be opened
        Profiler.logFile = "";
