Language Runtime Metrics
Last updated 06 November 2017
Table of Contents
To provide additional insights into memory health we offer optional language-specific runtime metrics. JVM, Go (public beta), and Ruby (private beta) are currently supported, with additional languages planned.
General Language Metrics Information
For all metrics the resolution is dependent on the timeframe selected. More information on metrics retention and resolution is available in the Application Metrics docs.
Language runtime metrics are available for all paid dynos (Hobby and above) and Private Spaces using the supported languages.
Setup Instructions and More Information
Please see the language-specific documentation for setup instructions and additional sample metrics:
Using with Pipelines
To use Language Runtime Metrics with Heroku Pipelines, you must follow the setup instructions for the most downstream app in the pipeline (the one you deploy to before promoting). Then you must enable the feature in the metrics dashboard of any upstream apps in the pipeline before promoting.
If your downstream app is a Free tier app, you must follow all of the setup instructions expect enabling the feature in the Metrics Dashboard (for example, you must still add a buildpack or a new dependency to the free app). The feature will not work on the Free app, but any paid dynos downstream will be ready to use the feature once you promote.
