Ruby agent requirements and supported frameworks

Before you install New Relic's Ruby agent, make sure you meet these requirements for compatible operating systems, security requirements, and supported frameworks.

Operating systems

The Ruby agent supports UNIX-like operating systems such as Linux, Solaris, FreeBSD, and macOS.

Security requirements

As a standard security measure for data collection, your app server must support SHA-2 (256-bit). SHA-1 is not supported.

Other APM software

If your application uses other application performance monitoring (APM) software besides our agent, we cannot guarantee that our agent will work correctly and we cannot offer technical support. For more information, see Errors when using other monitoring software.

Instance details

New Relic collects instance details for a variety of databases and database drivers. The ability to view specific instances and the types of database information in APM depends on your New Relic agent version.

New Relic's Ruby agent version 3.17.0 or higher supports the following ORM databases:

ORM Database Adapter name Minimum agent version
ActiveRecord 5 or higher PostgreSQL pg 3.17.0
MySQL mysql2 3.17.0
ActiveRecord 2.1 to 4 PostgreSQL pg 3.17.0
MySQL mysql 3.17.0
MySQL mysql2 3.17.0

The Ruby agent also supports these gem databases:

Gem database Gem name Minimum gem version Minimum agent version
Memcached Dalli 2.6.4 3.17.1
Mongo DB mongo 2.1.0 3.17.1
Redis redis-rb 3.0.0 3.17.1

Connect the agent to other parts of New Relic

The Ruby agent integrates with other New Relic capabilities to give you end-to-end visibility.

Capability Integration
Browser monitoring The Ruby agent automatically injects the Browser JavaScript agent when you enable auto-instrumentation. After enabling Browser injection, you can view Browser data in the APM Summary page and quickly switch between the APM and Browser data for a particular app. For configuration options and manual instrumentation, see the browser and Ruby agent documentation.
Infrastructure monitoring When you install the Infrastructure and APM agents on the same host, they automatically detect one another. You can then view a list of hosts in the APM UI, and filter your Infrastructure hosts by APM app in the Infrastructure UI. For more information, see APM data in infrastructure monitoring.
Synthetic monitoring Synthetic transaction traces connect requests from Synthetics monitors to the underlying APM transaction.
