I have warning logs in server.log :
WARN [NettyTransport] receiveBufferSize (SO_RCVBUF) for input XXX should be 1048576 but is 212992.
I have 2 inputs (1 syslog TCP and 1 GELF TCP) and both are concerned by this warning messages.
The size 1048576 is the default size configured when I created the inputs.
So I have 2 questions :
- What is the role of this buffer ? What is its aim ?
- Why does I get this warning logs ? Is it important ? Must I resolve them ?
