How do I log to a new file every day in rails?

Question

I am looking for a solution that will allow me to create a new log file for rails application everyday.

The goal is to go from standard production.log to

production.2019-06-01.log

production.2019-06-02.log

...etc

Where the latest log is has today's date.

I am aware of logrotate application but the issue is that production.log is current one, production.log.1 is supposedly yesterdays. So if you want to find something that happened on a specific day few weeks ago, you'll need to eyeball which log file it will be in.

you can configure logrotate to do what you need check daily and dateext options here https://linux.die.net/man/8/logrotate. also you can use the more modern way and use something like ELK https://www.elastic.co/elk-stack to index the logs in elasticsearch and use kibana dashboard to search your logs easily.

did you try :

logger = Logger.new('production.log', 'daily') # or 'weekly', 'monthly'

To get the desired output use :

t = Time.now()
file = 'production.' + (t.strftime("%m-%d-%y")) + '.log' 
logger = Logger.new(file, 'daily') # or 'weekly', 'monthly'

All great answers! I am currently running on tomcat, so I utilized the default java logging classes to do this.
