It should only print logs at ERROR and WARN levels by default, what logging outputs were you seeing?

panjf2000 commented 8 months ago

The logging module of gnet is pluggable, which means that you are free to replace the default logger with your own customized logger. If you want to disable the default logger, you can set the environment variable GNET_LOGGING_LEVEL to the highest level FatalLevel (which is "5") before starting your gnet services.

@panjf2000 it was under ddos attack, i'm using github.com/IceFireDB/redhub which uses gnet.

it doesnt show any logs output. do u think it's doing something without showing anything? i put icefiredb under ants.Submit "goroutine". just wondering if it's advisable to use ants on top of gnet services etc.
