Apollo: How to view Apollo modules errors and print lines?

[snuffysasa]

Hello,

I am just getting started with Apollo. And I launch the modules from dreamviewer or with the scripts.. that say module launched successfully. But I never see any error messages or print to console messages, how can I turn on debug mode so I can see standard out and error messages, so that I can do my own editing and debugging.

Thank you

The short answer is you can not see debug message in the DreamView console, without a lot of work.
To view Debug message, go to data/log folder you will see text files with debug message from different modules.
To enable debug mode, for example in planning module: add --v=4 at the end of modules/planning/conf/planning.conf

Okay thank you.

Does that work for all modules?

Will it show all kinds of print lines?

You can modify how each module is launched in modules/tools/supervisord/dev.conf (or release.conf). To change the verbosity level, just add --minloglevel option, e.g. --minloglevel=2 ( you can set it to be 1, 2, or 3).

Thank you.

Is this going to put the log messages in the ubuntu terminal? or in Dreamview console?

As an example, here is how canbus is started in dev.conf:

[program:canbus]
command=/apollo/bazel-bin/modules/canbus/canbus --flagfile=/apollo/modules/canbus/conf/canbus.conf --log_dir=/apollo/data/log
autostart=false
numprocs=1
exitcodes=0
stopsignal=SIGINT
startretries=10
autorestart=unexpected
redirect_stderr=true
stdout_logfile=/apollo/data/log/canbus.out

Just play with redirect_stderr and stdout_logfile. You can figure it out then.
