Anyone have any suggested tools or plugins to monitor a rail  
application in production?

What kind of monitoring do you need to do? We use nagios to monitor  
uptime.

Many people use monit with success. This also looks promising:

I need to monitor the ‘health’ of the application more then just  
uptime. What do others monitor in production rails applications  
besides uptime?

I’ve not tried many, but monit(already mentioned) is pretty slick -  
plus it provides a dsl to heal broken services.

#8000  
check process mongrel-8000 with pidfile /var/www/the-soup/shared/log/  
mongrel.8000.pid  
start program = “/usr/local/bin/ruby /usr/bin/mongrel\_rails  
start --user deploy --group mongrel -e production -d -c /var/www/the-  
soup/current/ -p 8000 -P /var/www/the-soup/current/log/mongrel.  
8000.pid -r /var/www/the-soup/current/public/”  
stop program = “/usr/local/bin/ruby /usr/bin/mongrel\_rails stop -  
c /var/www/the-soup/current/ -p 8000 -P /var/www/the-soup/current/log/  
mongrel.8000.pid”

```
 if totalmem > 85.0 MB for 5 cycles then restart
 if failed port 8000 protocol http
     with timeout 10 seconds
     then restart
 group www

```

Plus also provides an http service for stats monitoring and control.
