On a PC press Control + Alt + F6 when you are playing a game to see advanced streaming stats. Please note some notebooks may require you to press a fn key to access F6.
On a Mac, Press Option + Command + F6 at any time to see advanced streaming stats. The network stats will look similar to the picture below. Please note on a MacBook you may need to press fn + 6 to for the F6 command.
Here’s what the different numbers mean:
First Line:
- ###fps – average frame rate, based on frame-to-frame present time
- ft:###ms – average frame-to-frame receive time from server
- fj:###ms – average frame-to-frame receive time jitter (negative = early, positive = late)
- r:##mb – average streaming rate
- bwu:##% - bandwidth utilization as percentage.
Second Line:
- ######## - ~frame number
- rtd: ###ms – round trip delay from client to server
- pl: ### - packet loss (note there may be more than one packet per video frame)
- %cpu: ##.# - on mac, the percentage of 1 core the process is using. (> 100% means using more than 1 core). Should be similar to Activity Monitor on Mac.
Third Line:
- b: ####ms – ‘begin’ time – the latency between receipt of packet to start of processing
- d: ####ms – ‘decode’ time – the latency from begin to decode complete
- r: ####ms – ‘render’ time – the latency from decode complete to render complete
- p:####ms – ‘present’ time – the latency from render complete to post-swap-buffers
- t: ####ms – ‘total’ time – add up all of the above for total latency through the client.
Fourth Line:
- wr: ###x### - window resolution
- sr: ###x### - streaming resolution (may vary due to network quality)
- sq: ### - ‘q score’ – or Quality score represents the overall streaming quality that the user is currently experiencing, where 100 is perfect and values near 0 are unplayable
- e: #### - number of input events processed
Fifth Line:
- gpu: ####### - type of GPU used on the server for this session
- input: alt|sdl - alt: using direct input events from system, sdl: using input events from SDL library
On Android and SHIELD, Two-Finger double tap or hold LT and LB while closing the on screen controls (Hold START to open the On screen controls)
On Chromebooks, press Ctrl + Alt + F6. To press F6, see these instructions:
First Line:
- ###fps – average frame decode rate, based on number of frames decoded and time taken. There is a standard stats defination in webrtc, but not yet implemented.
- j:#.###ms – average network packet jitter
- r:##Mbps – average streaming rate [avg bytes received per second] in Mb
- bwu:## - bandwidth utilization as percentage.
Second Line:
- fd: The total numbers of frame decoded.
- fr: The total numbers of frame received.
- fdr: The total number of frames dropped prior to decode or dropped because the frame missed its display deadline for this receiver's track
- ft:### – average frame-to-frame decode time in client in ms
Third Line:
- rtd: ###ms – round trip delay from client to server
- pl: ### - packet loss (note there may be more than one packet per video frame)
- d: avg decode time ( Total decode time / frames decoded.)
- fl: approx frame lost. ( pliCount from webrtc stats)
Fourth Line:
- wr: ###x### - client window resolution, which in full screen means the logical resolution of the display as reported by the OS
- sr: ###x### - streaming resolution, which is initially established based on your client window resolution and may vary due to network conditions (DRC)
- sq: ### - ‘q score’ – or Quality score represents the overall streaming quality that the user is currently experiencing, where 100 is perfect and values near 0 are unplayable
