Your Apps Have Evolved. Your API Monitoring Should, Too.

As applications have grown to encompass ever more functionality, versatility, and connection, they’ve moved from monolithic to more modular, service-based architectures. This more distributed nature of new applications means they often rely on several external third-party services, backend integrations, and cloud APIs outside their control, as well as sensitive internal and backend APIs.

In order to deliver a reliable digital experience, ITOps and DevOps teams must be able to accurately measure performance and test critical workflows for internal and external API endpoints. To do so, they need an API monitoring tool that provides detailed performance metrics that go beyond basic uptime, downtime, and latency data.

Adaptive API Visibility for Your Applications

ThousandEyes provides ITOps, SREs, and DevOps teams the API visibility they need to address performance thresholds and reachability issues for API calls across every composite application service and multi-service interaction. With our advanced API testing, you can perform comprehensive API monitoring and baselining, including on third-party APIs. Connecting the user experience state with the backend application systems integrated with Splunk Observability Cloud, this capability provides an integrated view of both application functionality and network performance—essential for gaining a complete understanding of the service delivery chain across any network.

Adaptive API Visibility for Your Applications

See Across the Internet and External Networks as If You Owned Them

  • Utilize hop-by-hop path visualizations to uncover issues along API service delivery paths, offering critical insights for efficient troubleshooting and system optimization.
  • Get visibility into distributed services dependencies, including where they are being served from and by whom, how they impact overall service delivery, and how they are affected by external conditions like outages.
  • Access instant insights into app experience, powered by data from cloud vantage points across 200+ cities around the globe.

Access Insight Into the End User’s Perspective Across Complex API Workflows

  • API Monitoring provides a multi-step test that emulates backend application interactions with API endpoints for an accessible, intuitive, and simplified workflow with templates and dashboards.
  • Measure the performance of your own API gateway—or a third-party’s (like the Amazon API Gateway for AWS), particularly if the APIs are served in a hybrid cloud environment. 
  • Visual validation of API response content, including third-party API calls, helps users quickly and clearly confirm whether API responses meet expected criteria.

Gain a Common Operating Language Between DevOps, NetOps, and Service Providers

  • Real-time, historical, and multi-service snapshot views of API reachability and performance allow you to gain a comprehensive understanding of your environment—helping you select the best APIs for your web applications.
  • Interactive snapshots offer an easy way to escalate issues with providers and internal teams and optimize response times.
  • Intuitive API test creation helps you set up baseline tests and easily expand them as your needs evolve. Go beyond simple availability checks by adding assertions for data integrity, extending monitoring to multi-step scenarios, and creating variations to thoroughly test edge cases—helping you maintain robust performance in any situation.
