Analyzer go-alloc-fgraph

# Name

go-alloc-fgraph - Go Memory Allocation Flame Graph

This analyzer profiles memory allocation patterns in Go applications by tracing allocation call sites. It generates flame graphs visualizing the frequency and volume of memory allocations across different code paths. The analyzer is crucial for identifying excessive allocations, optimizing garbage collection pressure, and improving overall memory efficiency in Go applications.

# Resource Category

CPU.

# Application Type & Technical Stack

• Go

# 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 go-alloc-fgraph -p PID

# trace a shell command directly
orxray analyzer run go-alloc-fgraph -c SHELL_CMD

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

# trace any processes started from the specified executable path.
orxray analyzer run go-alloc-fgraph --exe /path/to/exe/file

# Tracing Multiple Processes

Supported.

# Output Formats

• Flame Graphs
