Kubernetes Cluster Logging with the OpenTelemetry Collector and ClickHouse®

Logs may be looked down upon by today’s observability thought leaders, but there is a reason they are the first pillar of observability: there’s a relevant log message at the end of almost every debugging journey! Collecting those logs from applications and infrastructure in a standard format is now trivial thanks to the OpenTelemetry Collector, and we get to keep it in the same format — and potentially the same database — as our other telemetry signals like traces, metrics, and profiles.

In this webinar, we’ll show how to use the OpenTelemetry Collector to gather all application and cluster logs from a Kubernetes cluster. We’ll use ClickHouse to store and query our logs and Grafana to visualize trends. By the end of the session, you’ll have everything you need to standardize your cluster logs on the most forward-looking format available today: OpenTelemetry.
