Log files
The ChirpStack components are writing their log output to Syslog,
which writes to /var/log/messages.
All logs
To view the logs, run:
sudo tail -f /var/log/messages
By service
To filter the messages by a specific service (e.g. chirpstack-concentratord),
run:
sudo tail -f /var/log/messages |grep chirpstack-concentratord
