Sow info about ballooning with the memory info #286
Description
When Memory Ballooning is enabled, the "MEMORY" content should show info about it, to better understand what could happen when the memory is full but no processes seems using it.
As an example:
MEMORY
Stats graphed as percent of MemTotal:
MemUsed ▊▊▊▊▊▊▊▊▊▊▊▊▊▊▊▊▊▊▊▊▊▊▊▊▊▊▊▊▊▊▊▊▊▊▊▊▊▊▊▊▊▊▊▊▊▊▊▊▊▊ 99.1%
Buffers .................................................. 0.0%
Cached ▊▊▊▊▊▊▊▊▊▊▊....................................... 21.7%
HugePages .................................................. 0.0%
Dirty .................................................. 0.5%
RAM:
31.5 GiB total ram
31.1 GiB (99%) used
24.3 GiB (77%) used excluding Buffers/Cached
0.15 GiB (0%) dirty
But all the processes running doesn't show that memory in use. Based on [1] and the info in section "Sosreport from VMware virtual machine", checking for the guest.mem.ballooned the following is shown:
$ grep guest.mem.ballooned sos_commands/vmware/vmware-toolbox-cmd_stat_raw_text_resources
guest.mem.ballooned = 16712052
The "MEMORY" content should show that ~16.7GB are ballooned.
