-------------------------------------------------------------------
I would say:
# Yes to {{TRACE}} level, and that should probably be part of GUACAMOLE-422.
# We should add an empty handler for {{nop}}, as it's a legit instruction
(probably makes sense to be part of GUACAMOLE-422 there, too).
# Those empty opcodes are handled by the Java side of the tunnel
implementation. There's something strange about this deployment if they are
being received by guacd. They are explicitly filtered:

> Debug level guacd logs spammed with "Handler not found for"
> -----------------------------------------------------------
>
> Key: GUACAMOLE-854
> URL: https://issues.apache.org/jira/browse/GUACAMOLE-854
> Project: Guacamole
> Issue Type: Bug
> Affects Versions: 1.1.0
> Environment: guacd: staging/1.1.0
> guacamole-common-js: staging/1.1.0
> Reporter: Richard Lancaster
> Priority: Minor
>
> When running guacd with DEBUG level logs, the logs are spammed with:
> {noformat}
> guacd[9]: DEBUG: Handler not found for "nop"
> guacd[9]: DEBUG: Handler not found for ""
> guacd[9]: DEBUG: Handler not found for ""
> guacd[9]: DEBUG: Handler not found for ""
> guacd[9]: DEBUG: Handler not found for ""
> guacd[9]: DEBUG: Handler not found for ""
> guacd[9]: DEBUG: Handler not found for "nop"
> guacd[9]: DEBUG: Handler not found for ""
> guacd[9]: DEBUG: Handler not found for ""
> guacd[9]: DEBUG: Handler not found for ""
> guacd[9]: DEBUG: Handler not found for ""
> guacd[9]: DEBUG: Handler not found for ""
> {noformat}
> I think the empty strings are caused by these instructions:
> `0.,4.ping,13.1563882935963`.
