Analyzer cpu-hogs

# Name

cpu-hogs - cpu hogs of the system

This analyzer identifies processes consuming the most CPU resources on the system. It monitors CPU usage across all running processes and generates bar charts showing the top CPU consumers. The analyzer helps quickly pinpoint resource-intensive applications and diagnose system-wide performance degradation caused by CPU contention.

# Resource Category

CPU.

# Application Type & Technical Stack

• All

# 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 cpu-hogs -p PID

# trace a shell command directly
orxray analyzer run cpu-hogs -c SHELL_CMD

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

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

# Tracing Multiple Processes

Supported.
