Why set up RubyVM monitoring?

With AppSignal's automated RubyVM dashboard, you gain instant insights into critical performance metrics of your Ruby application. With memory allocation, garbage collection, heap slots, and thread count metrics, you can identify memory leaks and runaway threads before they impact your application's performance.

Solve common RubyVM issues

AppSignal gives you instant insights into your application's metrics, helping you to answer important Ruby performance questions:

• Is garbage collection running?
• How many threads are running on my Ruby application?
• How much memory is being used by object allocation in my Ruby application?
• How many heap slots is my Ruby application using?

Monitor your RubyVM metrics with AppSignal

A simple click on any point of any graph on your dashboard will give you an instant snapshot of your application at that point in time. Dive deep into your RubyVM performance by visualizing the garbage collector's performance and thread count, along with easy access to your application logs for even faster debugging.

AppSignal dashboards give you the insights needed to make proactive and data-driven decisions. You can also stay ahead of issues by setting up triggers to alert you when your thread count begins to climb or garbage collection slows down.
