Changes to Heroku Data Service Metrics Log Format

Change effective on 14 July 2021

This change only impacts users of Private Space Logging.

At the time of publication, the format of the RFC 5424 Syslog frames sent to Private Space Log Drains, as part of Heroku Postgres Metrics Logs, Heroku Redis Metrics Logs, and Heroku Kafka Metrics Logs, will change to reflect the updated Writing to Application Logs as an Add-on Partner documentation.

The HOSTNAME field will now be the billing app UUID, and the APP-NAME field will now be the word app.

Previously, HOSTNAME would have been the service name (e.g. heroku-redis) and APP-NAME would have been the drain token/password, as parsed from the drain URL.
