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

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

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

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
