No memory statistics on Google Containers cos image

Hello,

Inside snap container I see following memory statistics:

cat /sys/fs/cgroup/memory/887c912cb6d972308903f360122d0252261160b1dcfedc364d578a08ba499d50/memory.stat

cache 143360
rss 546529280
rss_huge 0
mapped_file 32768
dirty 20480
writeback 0
pgpgin 175296
pgpgout 41831
pgfault 179253
pgmajfault 0
inactive_anon 0
active_anon 546529280

total_rss 546529280
total_rss_huge 0
total_mapped_file 32768
total_dirty 20480
total_writeback 0
total_pgpgin 175296

total_inactive_anon 0
total_active_anon 546529280
total_inactive_file 49152
total_active_file 94208
total_unevictable 0

But the Grafana graphs for CPU and memory statistics are empty for pods. There is no data in CPU/Memory whisper files (for any container)
