Automated Alert & Aggregation Rule Generation For CockroachDB Metrics

The blog post discusses the development of an automated alert and aggregation rule generation framework for CockroachDB metrics. Currently, CockroachDB outputs multiple metrics that indicate system health, but lacks a framework to provide additional information on how these metrics should be consumed and used for monitoring and debugging. The new framework will enable engineers to specify alerting and aggregation rules for metrics using PromQL syntax, which can be easily imported for usage in alerting/monitoring configurations. The framework aims to bridge the knowledge gap between metric implementation and usage by providing a mechanism for engineers to share more information on how to use the metric. Future work includes extending this framework to include support for generating automated Grafana dashboards for CockroachDB metrics.
