OpenInfra Days North America Talk at Indiana University: Modern Application Debugging: An Introduction to OpenTelemetry
In this talk, Joshua will share his insights and experiences with OpenTelemetry, an open-source project that offers protocols, APIs, and SDKs for collecting metrics, traces, and logs from applications and services. He will cover the comprehensive toolkit provided by the OpenTelemetry community, including language SDKs, the Collector, and the OTLP formats for metrics, traces, and logs.
He will demonstrate how to instrument and monitor a microservices application running on a Kubernetes cluster, utilizing the full potential of OpenTelemetry. Attendees will learn how to use powerful open-source tools like Jaeger and Prometheus to effectively analyze telemetry signals from their applications.
The Doctor Is In–Quick First Aid for Broken ClickHouse® Clusters
Properly managed ClickHouse servers are well-behaved, but every cluster runs into problems at some point.
In this webinar, we'll introduce common issues that require admin intervention or even application changes. Topics include too many connections, too many parts, lost replicas, stuck mutations, and too many detached parts on startup. In each case, we'll explain the problem, show you the symptoms, and give you the standard cures.
There will be extra time for questions, so bring your favorites. We'll be happy to offer opinions.
