Hey Brian,

Yeah, the normal configuration for the Toolkit is to only do outbound ping
tests since we can’t be sure that bwctl is running on the far side to do
inbound ping tests. I’m not sure about the graphing though. Bidirectional
tests can be configured with some config file modification.

Cheers,
Aaron
