监控终端和进程的输出工具:ispy

jopen 6年前

ISPY是一个Python工具,用于监控终端和进程的输出。

Demo

ispywatching abashsession that lists some files and opensvim:

The same thing, usingstrace:

Installation

pip install ispy

Alternatively, if you aren't a Python person or don't want to install it (since it must be run as root), you can download a fully packaged pex file and run without installing:

wget https://github.com/dellis23/ispy/blob/master/bin/pex/ispy.pex?raw=true -O ispy; chmod +x ispy

Usage

# ispy <pid_to_watch>

Use Cases

  • Watching someone else's terminal
  • Watching the output of a backgrounded process

Notes

Not intended for production!

It's probably buggy.

This was mainly an exercise in learning aboutptracefor myself. I haven't done anything more than smoke testing on a couple of operating systems.

This uses the same system call asstrace(ptrace), which is heavy-handed and has a performance impact. It is not recommended to use in production or against mission-critical applications. It's also written in Python, so it's even slower.

Supported OSs

This has been tested as working on:

  • Ubuntu
  • CentOS

This has been tested as not working on:
