Analyzer ngx-config

Name

ngx-config - Configurations for Nginx

This analyzer retrieves and presents comprehensive runtime configuration information from Nginx and OpenResty servers. It captures critical parameters including worker process settings, connection pool configurations, resource limits, listen addresses, system kernel parameters, and build options. The analyzer outputs structured data in tabular format with key metrics such as free connections, worker processes, and connection limits, facilitating capacity planning, performance tuning, and configuration validation for production environments.

Resource Category

Miscellaneous.

Application Type & Technical Stack

  • OpenResty
  • Nginx
  • APISIX
  • Kong

Command Line Syntax

The analyzer can be invoked directly on the command-line via the orxray utility from the openresty-xray-cli software package.

Alternatively, the analyzer can also be invoked manually or automatically on the web console UI of OpenResty XRay (like on the Advanced web page).

# PID is the target process PID.
orxray analyzer run ngx-config -p PID

# trace a shell command directly
orxray analyzer run ngx-config -c SHELL_CMD
