Starting Mosquitto in verbose/debug mode through /etc/init.d/mosquitto

[GeertVc]

I've installed Mosquitto on my Raspberry Pi through sudo apt-get install mosquitto mosquitto-clients python-mosquitto.
Thanks to the last part, python-mosquitto, I'm able to start/stop/restart/... Mosquitto through sudo /etc/init.d/mosquitto [start|stop|status|restart|...], which is nice.
However, I can also start Mosquitto "manually" with the verbose option through sudo mosquitto -v.

I would also like to have the chance to start Mosquitto in verbose and/or debug mode through the sudo /etc/init.d/mosquitto ... command.  I was thinking of adding this option into the /etc/mosquitto/mosquitto.conf file, but I can't find the right syntax and I'm also not sure if that's possible at all.  I tried to add verbose true into the configuration file (like there is persistence true, among others) in different flavours, but none of them is picked up correctly.

Is it possible through the configuration file and if so, how?

/etc/init.d forks processes so you won't see things like the verbose output, that's usually only for debugging. You might get close by trying "tail -f /var/log/mosquitto/mosquitto.log"

I tried this already before, but I don't get the output I see when I start Mosquitto "by hand" from the command line by adding the option -v.

If it's not possible, then I'll continue using the manual method....

Maybe just try reading the mosquitto.conf file a bit better....

There's a whole series of log_xxxx options you should have seen if you
had looked at the file. Or the documentation for the file...

@karlp: Rest assured, I did read the mosquitto.conf file which was put on my Raspberry Pi after installing Mosquitto.  And the "whole series of log_xxxx options" you're pointing at in your reply-with-a-slightly-arrogant-undertone boils down to, right, simply just one log_xxxx line.  So, a bit exaggerated, isn't it???

Here's the full content of the mosquitto.conf file as it appears just after a fresh Mosquitto installation on the RPi:

# Place your local configuration in /etc/mosquitto/conf.d/
#
# A full description of the configuration file is at
# /usr/share/doc/mosquitto/examples/mosquitto.conf.example

pid_file /var/run/mosquitto.pid

persistence true
persistence_location /var/lib/mosquitto/

log_dest file /var/log/mosquitto/mosquitto.log

include_dir /etc/mosquitto/conf.d

But I must admit, I didn't read the man page thoroughly enough.  And even better, you indirectly pointed me to the example mosquitto.conf file in /usr/share/doc/mosquitto/examples/, where I also found the solution to my problem.

Just in case other people face the same issue and because I like to help people if I found something useful for myself, here's the adapted mosquitto.conf file, which gives me at least the information I would see if I start Mosquitto manually with the -v option:

# Place your local configuration in /etc/mosquitto/conf.d/
#
# A full description of the configuration file is at
# /usr/share/doc/mosquitto/examples/mosquitto.conf.example

pid_file /var/run/mosquitto.pid

persistence true
persistence_location /var/lib/mosquitto/

# Added by GVC
log_type all
# End by GVC

log_dest file /var/log/mosquitto/mosquitto.log

include_dir /etc/mosquitto/conf.d

I only added one line, log_type all, which gave me the information I wanted to see appearing in the log file.  I "spy" the log file using the command tail -f /var/log/mosquitto/mosquitto.log.  Finetuning might still be needed, depending on one's needs, though...

To be complete, I also added the example mosquitto.conf file to this thread.
