⚡ Application Monitoring Tools

Web application monitoring tools allow developers and businesses to track the performance, availability, and health of websites and applications by collecting data from real user monitoring (RUM), server-side tracing, log analysis, and synthetic testing.

Often part of observability and application performance management (APM) platforms, these tools help detect errors, diagnose slowdowns, and optimize the user experience in real time.

According to our statistics, application monitoring tools are detected on 3.9% of all websites.
90.1% of these sites use only one application monitoring tool, 8.3% use two, and 1.6% use three or more of them.
