Get container memory

Glitch Help

i want to take container memory. i tried process.memoryUsage().heapUsed, Object.keys(process.memoryUsage()).filter(key => key != "heapTotal").reduce((a, b) => process.memoryUsage()[b] + a, 0), os.freemem() but it is giving more memory (like 50, 830) but my memory is 28 mb

Welcome @acarfy

To get the memory of the container you can read this file :

/sys/fs/cgroup/memory/memory.stat

But the data obtained will not be 100% accurate. The data present in the state tables are data calculated on an average, which are refreshed over a period of time to keep data consistent.

According to your screen, /sys/fs/cgroup/memory/memory.stat refers to total_rss

memory is 22 mb

values are

cache 6238208
rss 100818944
rss_huge 0
mapped_file 966656
dirty 0
writeback 0
pgpgin 148227
pgpgout 122090
pgfault 312410
pgmajfault 200
inactive_anon 50630656

This only takes into account the processes in use from the heap, this is only part of the full project usage.

so i can’t give 100% container memory usage, i can only approximate values? but my memory 22 but it gives 98. it need to give decrease value (like 12, 15, 8)? (sorry for my english)

What do you mean by this ?

my memory is 22
it gives 98
you sad it gives < 22? but

98 > 22?

This returns only the memory usage for the node process on which it is called, while the editor reports the memory usage of the container in the editor. There is a short delay between what is said (used) and what is displayed.
