You might want to stop running atop

Re: You might want to stop running atop
#92Linux newbie here. Jumped into the Linux world after getting tired of Microsoft's BS with Win 11. Running Linux mint on my laptop and desktop. Looks like 'atop' is not installed by default, but regular 'top'. Anyone know which distros I should be worried about that have it? Also I have been dabbling with proxmox, I checked and looks like 'top' is the default there too.
You're probably not running either unless you know what they are. Top is an equivalent of windows taskmanager, most often to used identify "top" processes using memory/cpu (and other resources) and only ran briefly. Atop is a different long-running version used to create logs of the same data to understand trends.

I would disagree and still say that this is bad vagueposting. It doesn't matter how reputable the source is: if you say "don't do X" but don't give a reason why, I'm not inclined to listen. Granted I don't use atop anyways, but I don't think a vague blog post - even one from a respected person - is sufficient justification to change what software one uses.
This attitude will eventually burn you.
seen this play out in real time, brutal

#95Is atop included in any distributions? Is there even a tool to search what is pre-installed in each major distribution(s)?
I typed 'atop' in my Linux Mint 22.1 laptop/desktop, says it's not found but can be installed. So I think Linux Mint is in the clear, I tried my Ubuntu 24.04 server and same thing there as well as my proxmox home lab instance. I checked that Repology link and I did see Ubuntu, but I guess that is for Ubuntu desktop but not sever edition? ps. If I said anything wrong, please correct me. I'm a linux newb who jumped fro…

Welcome to the dark side my friend, it's better here.

Nothing wrong, but if you ever want to see if something is present without actually running it, consider these commands:
ps aux | grep atop # is there a running process named atop?
which atop # is there a runnable command named atop on the PATH?
apt list --installed | grep atop # has apt installed a package named atop?
Re: You might want to stop running atop
#96At a previous gig, atop was running fleet-wide (> 1k servers) as sort of a resource monitoring tool of last resort, in a similar way as is described in this article[0]. I left a few years ago, but if memory serves, this thing was baked into base-image Puppet configs, and proved itself handy in past investigations of hard-to-find problems. If this turns to be real threat, I wouldn't be surprised if the blast radius for this is substantial.

Yeah, from a rando this would be just bad vagueposting but Rachel is absolutely someone who could know about a very good reason why we should uninstall atop but be unable to legally say why. I would heed her warning.

This seems completely backwards... if someone says to do something but doesn't give a reason, then the ONLY thing to base your decision on whether to listen is their reputation and your trust in them.
If someone I trust tells me to trust them, I will.

I can confirm my FreeBSD, Debian, and NixOS boxes don't have it installed by default. It's also not installed on my TrueNAS box.
