In my production.log file, I’m only seeing errors and database queries, etc. How should I go about generating an access.log and error.log (similar to apache). I’m interested in seeing the usual stats, request, referer, host, user-agent. – Anthony E. 408-656-2473 [http://anthony.ettinger.name](http://anthony.ettinger.name) ---

That’s all the responsibility of whatever http server you’re running. production.log is purely what Rails itself does. ---

This would be for mongrel then… On Mon, Jul 14, 2008 at 12:21 PM, Jason R. [removed\_email\_address@domain.invalid](mailto:removed_email_address@domain.invalid) wrote: > > referer, host, user-agent. > > > – Anthony E. 408-656-2473 [http://anthony.ettinger.name](http://anthony.ettinger.name) ---

Hmm, no, not mongrel, something like Apache, nginx, lighttp, etc. These are your front-end http servers, and they proxy down into Mongrel for running your Rails site. Jason ---

Not using those, I’m using mongrel stand alone, as suggested in the Deployment book. On Mon, Jul 14, 2008 at 2:10 PM, Jason R.

which deployment book? i would be surprised if a book about deploying ruby on rails suggests that you run mongrel alone in production. most resources that I’ve seen suggest apache or nginx proxying to mongrel. often it is proxying to a cluster of mongrels. for one reason, mongrel is slow at serving static files. also another issue of running mongrel alone, is that a mongrel can only deal with one request at a time, so of there are any tasks that are a little long, it will block other tasks from being run. this is why people use load-balancers to proxy to mongrel. also, using apache or nginx gives you the logs that you are looking for. nice. anyway, here are a few links: [http://blog.codahale.com/2006/06/19/time-for-a-grown-up-server-rails-mongrel-apache-capistrano-and-you/](http://blog.codahale.com/2006/06/19/time-for-a-grown-up-server-rails-mongrel-apache-capistrano-and-you/) > **[apache proxy balancer + mongrel clusters and deploying application with...](https://webonrails.com/2007/02/04/apache-proxy-balancer-mongrel-clusters-and-deploying-application-with-capistrano/)** > > How to setup or deploy rails application with mongrel cluster and apache proxy balancer?

Scott, ``` Having Mongrel (Thin, or whatever) standing alone, not proxied ``` behind a full fledged web server is unusual but it works. ``` If you have a box with plenty of resources and a bunch of small ``` apps servicing not so many requests, adding a reverse proxy arquitecture and clusters is overarquitecting. ``` But yes, it is unusual and if you want to gather webserver like ``` stats it would be better to install nginx, or you weapon of choice, and let it take care of logging and also serving the static files. – Aníbal Rojas > **[Home - Has Many Developers](https://hasmanydevelopers.com/)** > > We are the best choice for your building design and development > **[RUBYCORNER.COM](https://www.rubycorner.com/)** > > RUBYCORNER.COM - Contact us for any business inquiries [http://anibal.rojas.com.ve](http://anibal.rojas.com.ve) On Jul 15, 9:01 pm, “Scott Ballantyne” [removed\_email\_address@domain.invalid](mailto:removed_email_address@domain.invalid)
