Use Case

Resolve performance bottlenecks

OpenResty XRay shows how hardware resources, such as CPU time, wait time, I/O time, disk throughput, memory, and network bandwidth, are distributed across all code, data reference pathways and software layers in applications.

Use Case

Locate problems that are difficult to reproduce in production

OpenResty XRay can catch issues that are hard to reproduce even in the production environment, using an extremely low resource consuming and noninvasive approach along with sampling triggered by exception indicators.

Use Case

Collect online application performance metrics

Users can view collected metrics data in OpenResty XRay or export it to other data analytics platforms for visualization.
