Progress bar- The value above the bar is how much data has already been written to disk. The amount of data waiting to be processed in cases where your host computer cannot keep up with the amount of incoming trace data is shown below the bar. As the amount of backlog increases, so does the yellow fill in the progress bar. After you press the stop button, the backlog value will decrease. After it reaches zero, an analysis file is created. This process is visually represented by a green fill bar slowly replacing the yellow. Due to compression, backlog data size does not translate directly to disk usage amount. It will get smaller as the ARM Profiler processes it.

Total Instructions - The sum of instructions executed across all threads and processes.

Disk Space Remaining - The amount of disk space left on the host machine.
