I dont know why Ceilometing missing too much metric. Are there any ways to enhence it?

It's just the same for me...
I noticed an interesting thing, namely when the virtual machine works with kernel 4.15, for example, memory.resident is collected, while when kernel is 5.4 memory.resident is no longer collected.
I also checked if the supervisor sees the differences in /sys/fs/cgroup/memory/machine/qemu-165-instance-0000352e.libvirt-qemu/ but they do not differ when vm runs on kernel 4.15 or 5.4.
