Show HN: ClickStack – open-source Datadog alternative by ClickHouse and HyperDX 36 by mikeshi42 | 6 comments on Hacker News. Hey HN! Mike & Warren here from HyperDX (now part of ClickHouse)! We’ve been building ClickStack, an open source observability stack that helps you collect, centralize, search/viz/alert on your telemetry (logs, metrics, traces) in just a few minutes - all powered by ClickHouse (Apache2) for storage, HyperDX (MIT) for visualization and OpenTelemetry (Apache2) for ingestion. You can check out the quick start for spinning things up in the repo here: https://ift.tt/DPkOs4G ClickStack makes it really easy to instrument your application so you can go from bug reports of “my checkout didn’t go through” to a session replay of the user, backend API calls, to DB queries and infrastructure metrics related to that specific request in a single view. For those that might be migrating from Very Expensive Observability Vendor (TM) to something open source, more performant...
