Sunsetting Graphite ensures we stay ahead with a supported, scalable metrics platform for more effective long-term, multidimensional metrics analysis and storage.

This task aims to define an approach to configuring graphite as "read-only" to keep it serving historical data as the backlog and historicals populate on Prometheus post-migration.

Todo:

• identify viable approach
• test
• stage change for "production"
• enable read-only mode in production.
