Scout Ruby Deploy Tracking Config

Scout can track deploys, making it easier to correlate changes in your app to performance. To enable deploy tracking, first ensure you are on the latest version of scout_apm. See our upgrade instructions.

Scout identifies deploys via the following:

1. If you are using Capistrano, no extra configuration is required. Scout reads the contents of the REVISION and/or revisions.log file and parses out the SHA of the most recent release.
2. If you are using Heroku, enable Dyno Metadata. This adds a HEROKU_SLUG_COMMIT environment variable to your dynos, which Scout then associates with deploys.
3. If you are deploying via a custom approach, set a SCOUT_REVISION_SHA environment variable equal to the SHA of your latest release.
4. If the app resides in a Git repo, Scout parses the output of git rev-parse --short HEAD to determine the revision SHA.
