Amazon DCV server imaging

Counters in this set provide information about the subsystems responsible for screen grabbing, encoding and delivery.

Counters in this set are divided in two groups:

  • For those in the first group, Amazon DCV collects one value for each session and publishes it in the $session_name instance.

  • For those in the second group, Amazon DCV collects one value for each encoder in each session. There are three active encoders:

    • one full-frame encoder

    • one tile-based encoder

    • one lossless encoder

    These counters are published in the $session_name:$encoder_name instances.
