Analyzer rust-excep-fgraph

# Name

rust-excep-fgraph - Rust-Land Exception Flame Graph

This analyzer captures and profiles exception handling patterns in Rust applications by monitoring panic and error propagation paths. It collects stack traces when exceptions occur, providing visibility into error-prone code sections and exception handling overhead. The analyzer generates flame graphs that visualize the frequency and call paths of exceptions, helping developers identify reliability issues, improve error handling strategies, and reduce exception-related performance impact.

# Resource Category

# Application Type & Technical Stack

• Rust

# 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 rust-excep-fgraph -p PID

# trace a shell command directly
orxray analyzer run rust-excep-fgraph -c SHELL_CMD

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

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

# Tracing Multiple Processes

Supported.
