Do you see any other log files? You should be seeing some or all of:
go-agent-bootstrapper.out.log
*go-agent-launcher.log*
go-agent-stdout.log
go-agent-stderr.log
go-agent.log
I am especially interested in the launcher log file, which should have the
line I mentioned earlier ("Agent is version: 17.4 ...").
Do you see that?
Cheers,
Aravind
