How to access Redis log file

Have Redis setup with ruby on ubuntu server, but can't figure out how to access its log file. Tutorial says it should be here:

/var/log/redis_6379.log

But can't even find the /var/ folder

I recommend you to use redis-cli monitoring tool. Simple type the following command:

redis-cli monitor

It gives you a real-time access log which helps you troubleshoot the problems and...

vi /usr/local/etc/redis.conf

Look for dir, logfile

# The working directory.
#
# The DB will be written inside this directory, with the filename specified
# above using the 'dbfilename' configuration directive.
#
# The Append Only File will also be created inside this directory.
#
# Note that you must specify a directory here, not a file name.
dir /usr/local/var/db/redis/



# 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 "redis_log"

So the log file is created at /usr/local/var/db/redis/redis_log with the name redis_log

You can also try MONITOR command from redis-cli to review the number of commands executed.

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.

Check your error log file and then use the tail command as:

tail -200f /var/log/redis_6379.log

or 

 tail -200f /var/log/redis.log

According to your error file name..

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.
