APM Insight Ruby Agent is capable of identifying default methods and classes from multiple application frameworks. The agent automatically tracks identified methods and additional metrics, but, in some cases, performance data on these methods may not be enough to debug issues. When you need additional application-specific information to resolve an issue, you can use our API to collect application-specific metrics.
By default, the Ruby Agent only captures framework classes like Controllers, DB queries, and Views. You can use custom instrumentation to monitor other application-specific methods.
To get started, specify the methods to be instrumented in the application initializer, as shown below. Then create a new file named instrumentation.rb under config/initializers/.
This gives you in-depth details to troubleshoot and debug issues with your applications.
require 'agent/api/custom_tracker'MyClass.class_eval do
require 'agent/api/custom_tracker'ProjectsController.class_eval do
The APM Insight Ruby Agent is capable of capturing exceptions occurring in known framework methods. However, the agent can't track user-defined exceptions occurring in your application. In such cases, you can use the agent API to push exception data to Applications Manager server via the agent.
First, add the API in the application wherever necessary. Once the app server is started, the agent will capture the exceptions when they occur, automatically associate them with the current transaction, and push those exceptions to Applications Manager servers. This helps you track all exceptions from one place.
