Analyzer ngx-cpu-hottest-uris

# Name

ngx-cpu-hottest-uris - Showing the top 10 URIs order by request count

This analyzer profiles CPU-intensive URI endpoints in NGINX-based applications such as OpenResty, Kong, and APISIX. It tracks request frequency across different URI paths and identifies the most frequently accessed endpoints. The analyzer generates a bar chart displaying the top 10 URIs ranked by request count, helping pinpoint high-traffic endpoints that may be causing CPU bottlenecks or requiring performance optimization.

# Resource Category

# PGID is the process group ID or any process's PID within the target process
# group.
orxray analyzer run ngx-cpu-hottest-uris -p -PGID

# trace any processes started from the specified executable path.
orxray analyzer run ngx-cpu-hottest-uris --exe /path/to/exe/file
