I am Moshe the Founder @ Flanksource, and today we are releasing canary-checker, an open source, kubernetes native health check platform that provides a unified view of health across the entire stack.

Canary checker was born out of the need for platform teams (particularly those running on- premise or on less than perfect infrastructure) to understand the health of applications running on top of the platform.

Unlike other solutions such as prometheus blackbox exporter, kuberhealthy, and synthetic testing offered by major cloud providers, our approach goes beyond health collection.

Canary Checker enables health aggregation by ingesting alerts from Prometheus, Cloudwatch, Dynatrace, and for running full test suites using tools like K6, Playright, Robot, etc.. This approach provides a unified view of system health without the need to browse through many dashboards.

Canary Checker can also replace the need for multiple Prometheus exporters. It empowers you to export metrics from responses across 35+ supported protocols, including HTTP, SQL and Elasticsearch.

Something fairly unique to canary-checker is the ability to build stateful checks that use the results of a previous check in subsequent checks to generate metrics around historical data such as logs, logins, and activity stored in db tables.
