Analyzer java-socket-connect-fgraph

# Name

java-socket-connect-fgraph - Java Socket Connect and Accept Flame Graph

This analyzer attaches Linux connect and server accept latency to the Java call path that triggered each syscall. It renders separate connect and accept roots, so a wide path shows which Java code accounts for the largest accumulated time inside those kernel calls.

# Resource Category

Network I/O.

# Application Type & Technical Stack

• Java

# 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 java-socket-connect-fgraph -p PID

# trace a shell command directly
orxray analyzer run java-socket-connect-fgraph -c SHELL_CMD

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

# trace any processes started from the specified executable path.
