Spark Monitoring System Guide
The monitoring system in Spark refers to the tools and features provided by Spark for monitoring and managing Spark applications and clusters. This includes several aspects such as:
- Spark Web UI is a web interface provided by Spark that can be accessed through a browser to view the execution status, task running status, resource usage, etc. of applications.
- Spark monitoring metrics: Spark collects and exposes various performance metrics about applications and cluster, such as CPU utilization, memory usage, and task execution times.
- Third-party monitoring tools: Spark can also be integrated with third-party monitoring tools, such as Ganglia and Prometheus, to allow users to more comprehensively monitor Spark applications and clusters.
These monitoring systems allow users to monitor the execution status of Spark applications in real-time, enabling them to promptly identify and address issues, ultimately enhancing the performance and stability of the applications.
