Performance Monitoring Overview

To improve user experience, APM provides performance monitoring, which addresses issues such as a lack of O&M view, difficult-to-use topology, and insufficient association analysis.

Constraints

  • Only whitelisted users can use performance monitoring.
  • There are two editions for APM Agents: free and enterprise. After you switch from the free edition to the enterprise edition, the pay-per-use billing is used by default. You can purchase enterprise-edition preferential packages online. You can get discounts by buying these packages.

Function

Description

Monitoring Component Performance Metrics

The component details page displays the monitoring items of components.

Viewing the Call Relationships Between Microservices Through Tracing

When the calls between enterprise microservices are complex, Agents sample some requests, and intercept corresponding requests and subsequent call information. You can view the call relationships between microservices through tracing.

Viewing the Call Relationships Between Applications in the Global Topology

On the topology, you can view the call relationships between services and check whether the calls between services are normal to quickly locate faults.

Managing Performance Monitoring Agents

You can enable or disable APM Agents.
