µAPM Deployment Guide

To begin implementing SignalFx µAPM, you must deploy the SignalFx Smart Gateway in your environment, and the SignalFx Smart Agent on each host that runs traced applications.

The Smart Gateway observes every transaction across distributed services, generates metrics for each unique span and trace path, and prioritizes interesting outlier traces to forward to SignalFx as part of our NoSample™ Tail-Based Distributed Tracing feature. The Smart Gateway can be deployed as a scalable, self-coordinating cluster for high-availability and volume applications.

The Smart Agent reports basic system-level summary metrics about each host’s utilization, adds identifying metadata to each trace span as it forwards them to the Smart Gateway, and enables advanced correlation features between traces and infrastructure in SignalFx.

Instructions for deploying each of these elements are shown in the following sections.
