Monitoring tools like Prometheus, Sumo Logic, and Splunk can help QA teams track the impact of their work on application quality, establish universal KPIs to measure application health and performance, and justify investment in QA. By systematically monitoring applications in production, QA teams can draw relationships between testing routines and application quality, making it easier to plan and optimize QA operations. However, there is a risk that monitoring tools may be misused to make a case against QA, suggesting that sophisticated monitoring tools can replace the need for software testing. This is not entirely accurate, as APM tools are of little use for troubleshooting certain types of issues that QA excels at finding and addressing before deployment. Ultimately, monitoring tools are an important complementary resource for QA engineers, helping to make the overall importance of QA clearer and facilitating collaboration with developers and IT teams.
