ScyllaDB Monitoring Stack 2.1

ScyllaDB Monitoring Stack 2.1, released by the ScyllaDB team, is an open-source monitoring solution for ScyllaDB Enterprise and Open Source, leveraging Prometheus and Grafana. This version supports various ScyllaDB Open Source and Enterprise versions, as well as ScyllaDB Manager 1.3. Key updates in this release include an upgrade to Grafana 5.4.2, which introduces significant layout changes and a new URL path structure for dashboards. The monitoring stack now employs local file configurations for dashboards, plugins, and data sources, enhancing safety and upload speed. Additionally, clickable alerts allow users to navigate directly from alerts to specific dashboard views for detailed analysis. Customized dashboards are now more flexible due to backward compatibility with Grafana 5.x, although some attributes like row height are no longer supported. The make_dashboard.py script has been updated to generate Grafana 5 format dashboards with improvements in layout positioning.
