End-to-End Visibility

While Synthetics monitors detect website and API performance and availability issues, pinpointing backend issues that caused or are related to a failed monitor can be challenging. Identify the root cause of backend failures efficiently with Sematext all-in-one-platform.

  • Correlate failed run results with metrics from the service host around the time your monitor fails
  • Troubleshoot failed monitors using logs from backend applications and services invoked by the endpoint during monitor failures
  • Find the needle in the haystack. Eliminate noise by pinpointing logs specific to a single run using unique request IDs, ensuring focus on crucial information
  • Create custom dashboards to suit your website monitoring needs
  • Catch performance issues early by triggering runs as part of the CI/CD pipeline
