Download / Upgrade FSO Agent for Applications Manager

Enhance your monitoring with the Applications Manager Full Stack Observability (FSO) Agent—a lightweight, unified agent that provides end-to-end visibility across servers, applications, and services on Windows and Linux/Unix platforms. The FSO Agent combines Server Agent monitoring for key system metrics such as CPU, memory, disk, and network usage with AppLogs monitoring for centralized log collection and analysis.

Applications Manager simplifies FSO Agent management through centralized control, efficient metric and log collection via built-in sub-agents, and streamlined upgrades. Keeping the FSO Agent up to date ensures access to the latest observability features, fixes, and performance improvements while maintaining compatibility, stability, and accurate full-stack monitoring.
