ClickHouse is an open-source, high-performance analytics database designed for real-time data analysis on large datasets.
It uses a columnar storage format, allowing it to read only the data needed for each query. This makes it significantly faster than traditional row-based databases for analytics and reporting.
Observability with Pulse
Pulse provides ClickHouse observability by providing a unified platform to monitor query performance, system health, resource utilization across clusters, etc.
This capability enables you to:
- Monitor ClickHouse component health (Keeper, Server, Web Server) in real time.
- Analyze logs to troubleshoot issues and correlate events.
- Track query performance and resource usage with visual insights.
- Trace query spans (individual query operations) in the Trace Timeline to visualize execution flow
- Detect and fix bottlenecks using Pulse custom alerts and charts.
- Build custom dashboards and visualizations for continuous observability and optimization.
Before You Begin
To view ClickHouse data in the Pulse UI, make sure you:
- Configure your Hadoop cluster to send metrics and query data to Pulse.
- Configure Pulse to process and display the collected ClickHouse metrics.
