ptools

This repository contains a collection of Linux utilities for inspecting the state of processes, modeled after the tools by the same name which exist on Solaris/Illumos.

Getting Started:

To build ptools, run the following on an Ubuntu 18.04 VM:

$ git clone https://github.com/delphix/ptools.git
$ cd ptools/
$ curl https://sh.rustup.rs -sSf | bash -s -- -y
$ cargo build

The utilities can be run out of the target/debug directory, e.g.

$ ./target/debug/ptree 1

To install ptools, additionally run:

$ cargo install cargo-deb
$ cargo deb
$ sudo apt install ./target/debian/ptools_0.1.0_amd64.deb

Why ptools?

Linux already has a number of mechanisms which can be used to inspect the state of processes (the proc filesystem, ps, lsof, etc.). Why add a new set of tools?

The main advantage of ptools is consistency. The utilities provided by ptools are consistently named and have a consistent interface. Also, significantly, they can be run against core dumps where applicable, providing a uniform way to examine live processes and core dumps. This is very useful for those who rely heavily on core dumps to do postmortem debugging. The goal of this project is to make this same consistent debugging experience available on Linux.

Current State

Currently, this repository provides the following commands

  • pfiles - shows the open files and sockets of the process, as well as their corresponding file descriptors
  • pargs - shows the command line arguments passed to the process
  • penv - shows the environment of the process
  • ptree - shows the process tree containing the process

There are a number of other commands available on Solaris/Illumos which have not been implemented here yet, perhaps most notably pstack. Also support for examining core dumps has not yet been implemented.
