Hi
I have a golang file where I have code like:
log.Fatal("My error message: ", err)
When the above statement is executed, In the appengine logviewer, I get
something like:
panic: os.Exit called goroutine 1 [running]:
os.Exit(0x1)
go/src/os/proc.go:58
<https://console.cloud.google.com/debug/fromlog?appModule=default&appVersion=20171103t130151&file=go%2Fsrc%2Fos%2Fproc.go&line=58&logInsertId=59fc1ca5000391bb3a15d19c&logNanos=1509694618092435000&nestedLogIndex=0&project=celtic-facility-184703>

+0x201
But I dont get any error message. The main.go:42 corresponds to the
log.Fatal line in my code but I do not get to see the error message that is
printed as part of the log statement.
I see that appengine package has a "Log" function which may print the
AppLogs such that they can be viewed from the Google Appengine log console
itself.
My question is, can the golang default log package be somehow instructed to
redirect to appengine ? Something like:
if env == "AppEngine" {
log.SetOutput(appengine.DefaultLogger)
}
in my main file ? This way, I get to make my code not locked to google
cloud and also can deploy existing code which uses log already.
Any pointers ?
Thanks.
