This document details how to enable RUM for the APM Profiler in your Ruby application running on Linux or Windows.
1. Install the Latest Version of the Agent and Profiler
- Windows Agent v4.32+
- Linux Agent v2.31+
- Ruby Profiler 1.15.0+
2. Enable RUM
Follow the RUM Getting Started guide to Enable RUM on your account.
3. Setup APM for your Application
Follow the Ruby Getting Started Guide to configure the profiler for your specific setup. The profiler will need to be properly configured for RUM to function.
4. Configure the RUM Key
In order to identify the data coming from your application pages is tied to your account, you need to make your RUM Key available to your application. This setting is passed to your application via an environment variable,
Add the RETRACE_RUM_KEY to the machine Environment Variables. Its value is the RUM Key available in the Retrace RUM configuration screen.
Set the RETRACE_RUM_KEY environment variable so that it is available to the application when it launches. This will vary based on how the application is launched (e.g. via systemd or command line).
rum_enabled: true and
rum_key: 'RumKey' variable so that it is available to the application when it launches. Depending on how the setting for Stackify APM is set:
--- application_name: 'Sandbox Ruby' environment_name: 'Sandbox' rum_enabled: true rum_key: 'SomeRumKey'
5. Inject Script into Page
The Ruby profiler supports two methods to inject the script into your HTML pages. It supports Rails and Rack for the middleware for the automated injection.
Automatic Injection is enabled by setting the environment variable
RETRACE_RUMV2_ENABLED to the value of
'true' or using the Configuration Setup.
The manual injection method is available on the
- For Rails:
<%= raw(StackifyRubyAPM.inject_rum_script) %>
Note: (Rails has a function that will convert any manual injected tags to htmlentities)
- For Non Rails:
<%= StackifyRubyAPM.inject_rum_script %>
Manual Injection via API
The manual injection method requires that an API call to the Profiler is inserted into the HTML files without any quoting of the injectected string.
# Configuration - Standard API Stackify.setup do |config| ... config.rum_key = "YourRumKey" end # Use this to apply on views Stackify.rum.insert_rum_script
This API method is available in
stackify-api-ruby versions 1.3.0 and greater.
6. Redeploy your App
Once the previous steps to enable RUM for your account and add the code snippet to your app(s) have been completed, the last step is to deploy the changes to your application.
Viewing RUM Data
Once the following steps have been taken to set up RUM for your apps, data will be reported in the corresponding App Dashboard. To see more information related to what RUM data is presented in the App Dashboard, see the Viewing RUM Data in Retrace help doc.
