Could this be backported to 58?

Notes about testing: - ssh to VM - make sure you have swap enabled: -- `free -h` will show how much swap memory you have -- if zero, let's create swapfile, you can use this instruction: https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/storage_administration_guide/ch-swapspace#swap-creating-file - install `stress` utility - use `stress --vm-bytes $(awk '/MemAvailable/{printf "%d\n", $2 * 1.6;}' < /proc/meminfo)k --vm-keep -m 1` to utilize memory (where "1.6" is the coefficient to the memory available, it means "100% of available memory and 60% more, which should use swap") - wait 10-20 minutes to see new metric values (because they are "average", they will not be changed immediately)
