xsos -om OR xsos --os --mem would show something like the following:
xsos -cln OR xsos --cpu --lspci --net could show this:
xsos -e OR xsos --ethtool output looks like this:
The goal of xsos is to make it easy to instantaneously gather information about a system together in an easy-to-read-summary, whether that system is the localhost on which xsos is being run or a system for which you have an unpacked sosreport.
There is tons of useful amazing instructive data available to normal users (not to mention root) on a Linux system, but by design, this information is spread out across myriad files. Some of it even requires commands to parse through.
xsos will attempt to make it easy, parsing and calculating and formatting data from dozens of files (and commands) to give you a detailed overview about a system, or -- if requested -- xsos will only parse one file (e.g. with --mem or --cpu) or output from one command (e.g. with --ip or --ps).
New features are being added all the time -- see the tracker to have a look at some of the things that are already in line to be worked on.
Why another tool? Why not add stuff to sxconsole?
"I'm sold! How do I install xsos?"
Two choices:
-
Manual install: Get the very latest (potentially bleeding-edge) version directly by downloading the main xsos file from bit.ly/xsos-direct (which points to raw.github.com/ryran/xsos/master/xsos). Updating will need to be done manually (either by re-downloading or by running
xsos --update). Explicitly, you could run the following as root:wget -O /usr/local/bin/xsos bit.ly/xsos-direct chmod +x /usr/local/bin/xsos -
RPM/Yum repo (recommended): Configure access to the Fedora/RHEL6+ yum repository @ people.redhat.com/rsawhill/rpms and install the [potentially not-as-bleeding-edge] xsos rpm from there. Updating can happen automatically along with the rest of your system. Two-step instructions @ How to install xsos or rsar via yum?
Once xsos is installed by one of the above methods, run xsos -h as a normal user to see the help page and get started.
The lovely thing that isn't going to be captured here is all the coloring done to make things easier to read. There's actually quite a bit of color-logic to warn of various conditions...

- As detailed in the help page, BASH version 4 (rhel 6+) is required for -i/--ip and for any of the "Special options" like
--Cor--B. Colorization is also not done unless BASH v4+ is detected. - Other than that, nothing special for command requirements --
xsosuses standard coreutils & util-linux commands, along with, of course ...gawkandsed. - No absolute paths used for commands.
- When running on localhost (i.e. not a sosreport),
xsosgracefully reports as much of what's requested as possible when running as non-root (--biosand--ethtoolrequire root privileges;--diskswon't be able to print dm-multipath output without root privs).
- xsos does some pretty intensive color-formatting to make the output more easily-readable (can be disabled with
-xor--nocolorand colors can be modified via environment variables).- If you like the color but need to use a pager, use the
--less(-y) or--more(-z) options to auto-pipe output toless -SRormore.
- If you like the color but need to use a pager, use the
- There are a bunch of environment variables that you can use to tweak behavior. See the original commit comment for documentation.
- xsos can update itself via the internet in 10 seconds if run with
--updateor-U.- Set environment variable
XSOS_UPDATE_CONFIRMto "n" if you don't want--updateto prompt for confirmation.
- Set environment variable
- There's a bash autocompletion function defition available for xsos. Use it.
- When printing disk info with
-d/--disks, xsos automatically detects linux software raid (md) devices and hides their components. Themultipathcommand is also consulted to print info about native multipathd devices. All LUNs that are part of a dm-multipath map are also hidden from the disk output. - You can use the
--unit(-u) option to change how/proc/meminfoand/proc/net/devare parsed -- displaying units in anything from bytes up to tebibytes. Note that this option does not affect display of theVSZ&RSSfields in the ps output. (For that, manually set theXSOS_PS_UNITvariable tok,m, org.)
As far as direct contributions go, so far it's just me, ryran, aka rsaw, aka Ryan Sawhill Aroha. That said, many folks have reported bugs and given suggestions for new features:
-
Patrick Talbert especially deserves a huge shout-out! Using xsos on sosreports while diagnosing networking issues, he's uncovered many an odd corner case and discussions with him have led to implementing new features and refining what the networking modules show.
-
Jamie Bainbridge has been so consistently kind and effusive in expressing his appreciation of xsos. The RFEs he has suggested (at least the ones we've implemented) have surely made xsos a more powerful tool.
-
Joe Wright was the first person to request a kdump module. Turned out to be a great idea!
When I was clueless in how to further my awk career early on, two prolific users over on StackOverflow -- Dennis Williamson and ghostdog74 -- each provided answers (to two separate questions) with code that was brilliantly instructive. My awk skills have since evolved far beyond what I was trying to do back then, but thanks definitely goes to both of them for that early inspiration.
Please contact me if you have ideas, suggestions, questions, or want to collaborate on this or something similar. For specific bugs and feature-requests, you can post a new issue on the tracker.
