Metrics Collection Agent

Understanding Metrics Collection Agents

Metrics collection agents function as lightweight, autonomous software services that operate close to data sources, minimizing latency and ensuring data integrity. Unlike traditional polling-based monitoring systems, modern collection agents are designed to handle the high-frequency, high-volume data characteristics typical of industrial environments while maintaining minimal system resource consumption.

The agent architecture enables seamless integration with industrial data historians, time-series databases, and metrics backends to provide comprehensive visibility into industrial operations.
