Better error reporting about supervisord HOT 14 CLOSED

Ok thanks, now it works! Had an old source...
Is there a way to get the version from supervisord? I really think its a nice feature to compare and know where you are...

from supervisord.

now the log will be appended to the previous log file if it's max size does not exceed the limit.

from supervisord.

any suggestion on the error message you want to get?

from supervisord.

Maybe capture the stdout from when the command was executed?

from supervisord.

The stdout/stderr can be redirect to file with program configure item "stdout_logfile"/"stderr_logfile". Also you can redirect the program stdout/stderr to syslog.

Okay there was no output, just a return code of 126.

Maybe the return code can be in the error message? For example, "fail to start program: return code 126".

exit status is added in the log, please try it

from supervisord.

There is something which bothers me. When a program exits with an exception, while having redirected stdout_logfile or/and stderr_logfile, the program restarts as expected, but the log files are reinitialized instead of appending the content to it. This makes almost impossible to see what happens with the programs. Any hints on how to sort this out?

Thanks for your answer, but that doesn’t happen to me... They get truncated everytime the app restarts... Since when is this implemented (version)? Is there a way to get the version...because ./supervisord -v doesnt work... How do you configure the max size limit?
Thanks in advance.

from supervisord.

What is your "stdout_logfile"? it is in absolute path or relative path?

The max size is configured with parameter stdout_logfile_maxbytes/stderr_logfile_maxbytes. If this parameter is not configured, its default size is 50M.

Have you sync your source code to the latest?

I tried, but now it can't even compile...and sadly go is not my primary language of use...
I first execute:

go get -u -v -d  github.com/ochinchina/supervisord

and then

GOOS=linux GOARCH=arm go build github.com/ochinchina/supervisord
# github.com/ochinchina/supervisord
/home/user/go/src/github.com/ochinchina/supervisord/set_user_id.go:10: unknown field 'NoSetGroups' in struct literal of type syscall.Credential

from supervisord.

Please use golang 1.9 to compile it

from supervisord.

it is a good idea for supervisor to print a version or build no.
I will add a command line command to print the version later.
