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?

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.

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. – Sidney de Moraes May 20 '20 at 12:27

Looks like Glances should have what you need:

glances --tree

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

This option was removed last year: https://github.com/nicolargo/glances/commit/631722992e76827ecee61797edd3ab218e28c94a – pkk Jun 07 '19 at 09:14

did anyone figure out an alternative to this now that even glances can't do it? – Nick Korostelev Aug 05 '20 at 18:13

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. – bright-star May 03 '14 at 03:08

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. – karatedog Jun 21 '16 at 17:20

To clarify what @TrevorAlexander said, siblings in the tree could be sorted against one another without breaking the tree display – Aaron J Lang Sep 02 '16 at 10:12

In htop version 3 (I believe, 3.0.3 to be exact) you can sort by other columns than pid even in tree mode.

See the changelog.

It's not perfect, because it doesn't aggregate memory from sub processes, but it's a nice feature nonetheless.
