Sorted tree view in htop or alternative?

Question

I am running a Debian flavor of Linux, and I use htop to keep track of memory usage, since it is more detailed than top. I can't seem to get it to sort by memory and display process trees at the same time. Is there a way to do this with htop or an alternative?

Solution 1

Looks like Glances should have what you need:

glances --tree

And then sort using commands m,t, i etc. Full command reference

Solution 2

A 2019 update on this 2014 question that ranked highly when searching for this topic is that htop has this built in now, and in the current version 2.2.0, simply pressing t in the default view generates a process hierarchy.

Solution 3

Not with htop (and probably with any other alternative) as both views are mutually exclusive: either you list processes sorted by memory, or respect the PPID/PID tree view. You can have both at the same time.

Sure, but since there is a hierarchical relationship there, you could aggregate the memory or CPU usage of the tree and then sort on that.

On one of my server htop 1.0.1 does indeed lists the processes and their threads in tree view and sorted by CPU% (based on the process cpu%). On my other server, there is htop 1.0.2 and setting sort by CPU% automatically clears the tree view.

To clarify what @TrevorAlexander said, siblings in the tree could be sorted against one another without breaking the tree display

This option was removed last year: github.com/nicolargo/glances/commit/…

I don't think this answers his question since pressing t only changes view to tree but keeps not allowing you to sort at the same time. I'm using version 2.0.2.

did anyone figure out an alternative to this now that even glances can't do it?
