Analyzer py-write-fgraph

# Name

py-write-fgraph - Python-Land Virtual File System Write Flame Graph

This analyzer profiles file system write operations in Python applications by capturing stack traces during virtual file system write calls. It tracks the frequency of write operations across different code paths. The analyzer generates flame graphs that visualize the distribution of write call counts, helping identify write-intensive code sections and optimize file write patterns in Python applications.

# Resource Category

Disk I/O.

# Application Type & Technical Stack

• Python

# 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 py-write-fgraph -p PID

# trace a shell command directly
orxray analyzer run py-write-fgraph -c SHELL_CMD

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

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

# Tracing Multiple Processes

Supported.
