Now with deep Rails instrumentation, flexible
trend alerts, performance suggests and more.
Go beyond Rails with open-source plugins. Monitor everything from one place.

Only $7/server!
Scout watches over your Rails app, alerting you before
your applications land in the emergency room.
Alerting you of trends (is your signup page slower today than yesterday?), finding SQL queries that
are missing indexes, and more.

Only $7/server!
Your infrastructure is always changing. Your monitoring system needs to keep up. With a plugin-based
system, Scout lets you monitor your entire system from one place.
From MySQL to Phusion Passenger to your own custom metrics, it's easy to use community-developed plugins
or roll your own.

Only $7/server!
Every minute, Scout scans your metrics, alerting you as things change.
Has your Rails app slowed dramatically in the past hour? Have user signups increased today?
Is the change related? Scout
identifies relationships you don't have time to detect.

Only $7/server!
