Monitoring ScyllaDB with the new ScyllaDB Prometheus API

As of ScyllaDB version 1.4, native support for Prometheus facilitates system monitoring by allowing seamless metrics exporting and integration with visualization tools like Grafana. ScyllaDB gathers various performance metrics, such as memory consumption and cache operations, which are crucial for maintaining system health and are utilized in tools like the nodetool utility. Prometheus, a project under the Cloud Native Computing Foundation, serves as a robust platform for monitoring, offering capabilities like graph visualization, mathematical computation, and alert triggering based on metric evaluations. The integration with ScyllaDB requires minimal configuration and leverages the same infrastructure as the previous collectd API, making it straightforward to add ScyllaDB servers to Prometheus targets. Additionally, ScyllaDB's setup script facilitates the installation of node_exporter for machine metrics collection, enhancing the comprehensiveness of the monitoring solution. Future enhancements to the ScyllaDB Prometheus API include the addition of histogram support and detailed metrics descriptions to improve monitoring efficacy.
