Redis: How to access Redis log file

Found it with:

sudo tail /var/log/redis/redis-server.log -n 100

So if the setup was more standard that should be:

sudo tail /var/log/redis_6379.log -n 100

This outputs the last 100 lines of the file.

Where your log file is located is in your configs that you can access with:

redis-cli CONFIG GET *

The log file may not always be shown using the above. In that case use

tail -f `less  /etc/redis/redis.conf | grep logfile|cut -d\  -f2`

You can also login to the redis-cli and use the MONITOR command to see what queries are happening against Redis.

The log file will be where the configuration file (usually /etc/redis/redis.conf) says it is :)

By default, logfile stdout which probably isn't what you are looking for. If redis is running daemonized, then that log configuration means logs will be sent to /dev/null, i.e. discarded.

Summary: set logfile /path/to/my/log/file.log in your config and redis logs will be written to that file.
