Provides metrics on Passengers internal state, including the number of application instances that are currently alive, the number of instances that are currently processing requests, and the number of idle instances.

Passenger Status ====================== Based on passenger_memory_stats Compatibility ------------- Works on Linux and Solaris. Sudo Usage ---------- The passenger-status program recommends that you run it would super user privileges to gain more information. This plugin is usable without the extra access rights, but you will need to add them if you want the full details. It's important to note though that it is not safe for you to transmit your super user password to us. You will need to address this access issue on your server. Our recommended procedure to handle this is: 1. Edit the sudoers file on your server to allow the user that runs the scout client listed in your crontab to be able to run passenger-status without a password. e.g. daemon ALL=NOPASSWD: /usr/bin/passenger-status 2. Login into Scout and edit your plugin settings to add sudo in front of the command name. e.g sudo /usr/bin/passenger-status
