Our Heroku users know how awesome the Librato Add-On is for tracking application performance and custom metrics on our favorite Platform-as-a-Service. It was already super easy to monitor Router metrics and Postgres metrics with our support for Heroku log-drains. Today we're pleased to announce that our Librato Add-on for Heroku is now able to record Router status codes and release events as annotations!
We're automatically capturing all 200, 300, 400 and 500-level status codes from the Heroku Router for your applications. Paid plans will have a new HTTP Status Codes dashboard containing all of their new status code metrics stacked in a single Instrument, and also broken out into individual charts for easier visibility. Development plans will enjoy a new instrument on their Overview dashboard containing all of these metrics at a glance.
Being able to correlate regressions with code deployments is immensely helpful, so we're also tracking your Heroku app releases as Librato annotations. Release annotations have been added to all Instruments on the Overview dashboard. Paid accounts can add them to any Instrument using the releases annotation name.
