APM and Observability Tools for Testers equips QA engineers and software testers with the knowledge and practical skills to monitor application performance, analyze logs, trace requests, diagnose issues, and improve software quality using modern observability platforms.
Duration 3 days – 21 hrs
Overview
The APM and Observability Tools for Testers Training Course is designed to provide software testers, QA teams, performance testers, and technical support teams with practical knowledge of Application Performance Monitoring and observability concepts.
This course focuses on how testers can use logs, metrics, traces, dashboards, alerts, and monitoring tools to understand application behavior, detect performance issues, investigate defects, validate system reliability, and support production readiness. Participants will learn how observability supports functional testing, performance testing, API testing, regression testing, incident investigation, and continuous quality improvement.
The course introduces common observability and APM tools such as Azure Application Insights, Grafana, Prometheus, Datadog, New Relic, Dynatrace, Splunk, Elastic/Kibana, and OpenTelemetry at a foundational level. The course is tool-flexible and may be customized depending on the client’s actual monitoring platform.
