Logging in qsfp_service #75

Closed bluecmd closed 6 years ago

bluecmd commented 6 years ago

Hi,

I fail to see how folly is configuredi n qsfp_service. In wedge_agent there is:

FOLLY_INIT_LOGGING_CONFIG("fboss=DBG2; default:async=true");

but this seems to be omitted in qsfp_service. I've been unsuccessful in trying to make any useful log messages appear except the ones that use VLOG().

Digging around in folloy I found references to the --logging variable. That seems to have done the trick.

E.g.:

dhtech@wedge1:/usr/local/bin$ sudo /usr/local/bin/qsfp_service -alsologtostderr -v=2000 -vmodule='EventBase=0,AsyncSocket=0,CP2112=0' -mode=wedge  --logging=.=DBG3
