auto">Describe the enhancement:

Currently the system module supports collecting cpu and io Pressure Stall Information metrics for cgroup v2:

system.process.cgroup.cpu.pressure.full.10.pct	Pressure over 10 seconds	float	gauge
system.process.cgroup.cpu.pressure.full.300.pct	Pressure over 300 seconds	float	gauge
system.process.cgroup.cpu.pressure.full.60.pct	Pressure over 60 seconds	float	gauge
system.process.cgroup.cpu.pressure.full.total	total Full pressure time	long	counter
system.process.cgroup.cpu.pressure.some.10.pct	Pressure over 10 seconds	float	gauge
system.process.cgroup.cpu.pressure.some.300.pct	Pressure over 300 seconds	float	gauge
system.process.cgroup.cpu.pressure.some.60.pct	Pressure over 60 seconds	float	gauge
system.process.cgroup.cpu.pressure.some.total	total Some pressure time	long	counter
system.process.cgroup.io.pressure.full.10.pct	Pressure over 10 seconds	float	gauge
system.process.cgroup.io.pressure.full.300.pct	Pressure over 300 seconds	float	gauge
system.process.cgroup.io.pressure.full.60.pct	Pressure over 60 seconds	float	gauge
system.process.cgroup.io.pressure.full.total	total Some pressure time	long	counter
system.process.cgroup.io.pressure.some.10.pct	Pressure over 10 seconds	float	gauge
system.process.cgroup.io.pressure.some.300.pct	Pressure over 300 seconds	float	gauge
system.process.cgroup.io.pressure.some.60.pct	Pressure over 60 seconds	float	gauge
system.process.cgroup.io.pressure.some.total	total Some pressure time	long	counter

We should do the same for memory. The existing linux.pressure dataset already does this at a host wide level.

Describe a specific use case for the enhancement or feature:

Required for complete monitoring of PSI metrics for cgroupv2.
