Details
vmstat lists various virtual memory statistics.
Supportdata2 includes vmstat in the Meminfo section since sd2-09.
In Supportdata-Probes it was never included (up to fw 7.39).
Excerpt from the proc(5) man page:
/proc/vmstat (since Linux 2.6.0)
This file displays various virtual memory statistics.
Each line of this file contains a single name-value pair,
delimited by white space. Some lines are present only if
the kernel was configured with suitable options. (In some
cases, the options required for particular files have
changed across kernel versions, so they are not listed
here. Details can be found by consulting the kernel
source code.) The following fields may be present:

A ** in the Mod column marks info from Supportdata2 probes, which will always stay incomplete.
A - in the Mod column marks manual research, the Firmware then shows where the Object occurs, not the Relation.

Showing all models using this object. Click any column header (click-wait-click) to sort the list by the respective data.
The (main/scrpn/boot/arm/prx/atom) label in the Model column shows which CPU is meant for models with multiple Linux instances.
Note that this list comes from Supportdata2 probes, which can have arbitrary settings and come from different firmware versions.
It doesn't say much if a model is not listed here. It may be a missing supportdata2 file or just a disabled feature.

Help Supportdata2
The data in this article is incomplete since it was manually collected using the Supportdata2 project.
Unlike the Supportdata-Probes which have been collected for years Supportdata2 is brand new and only has a few probes.
If you have access to a shell then please help to extend the Supportdata2 collection to improve this data.
It's easy and it's done in minutes. Please send created data as an Email attachment to the address listed here. Thanks!
