Key Questions Answered
How can I instrument a Next.js application for observability?
To instrument a Next.js application, you can use the ClickStack SDKs for both the frontend and backend. The ClickStack JavaScript SDK allows you to capture traces and user sessions in the browser, while the Node.js SDK provides built-in exception capturing and HTTP request tracking. This setup enables you to visualize and analyze performance metrics effectively.
What are the benefits of using ClickStack with ClickHouse?
ClickStack unifies observability and analytics by allowing you to collect and analyze logs, traces, and metrics in a single platform. This integration enhances the ability to correlate application performance with user behavior, providing a comprehensive view of application health and user experience.
What is the performance of ClickPy in handling large datasets?
ClickPy, powered by ClickHouse, handles over 1.8 trillion rows with sub-second query performance, even under high concurrency. This showcases ClickHouse's capability to manage large-scale analytics efficiently, making it suitable for real-time data exploration.
How do I deploy ClickStack locally?
To deploy ClickStack locally, you can use the provided Docker command to run an all-in-one image that includes ClickHouse, HyperDX, and the OpenTelemetry collector. This setup allows you to access the HyperDX UI locally and start collecting observability data immediately.
