Thanks for reporting this. The current icingadb-redis
default configuration should log to stdout, resulting in systemd forwarding the logs to journald.
# Specify the log file name. Also the empty string can be used to force
# Redis to log on the standard output. Note that if you use standard
# output for logging but daemonize, logs will be sent to /dev/null
logfile ""
However, if you have altered your /etc/icingadb-redis/icingadb-redis.conf
configuration file, it may not have been updated by your package manager. Thus I would advice you to
- either update your configuration file to the latest version or at least set
logfile ""
or - overwrite the systemd unit with the relevant
ReadWritePaths
as you have already posted.
