The Scylla team is pleased to announce the release of Scylla Monitoring Stack 3.0.1.

Scylla Monitoring Stack is an open-source stack for monitoring Scylla Enterprise and Scylla Open Source, based on Prometheus and Grafana. Scylla Monitoring Stack 3.0 supports:

• Scylla Open Source versions 2.3, 3.0 and 3.1
• Scylla Enterprise versions 2018.x and 2019.x
• Scylla Manager 1.4.x

Scylla Monitoring 3.0.1 adds support for ScyllaDB’s new Amazon DynamoDB compatible API (Project Alternator). To use the new Alternator dashboard:
