11:17 <apache2> ehirdoy1: you mean statically? I don't think so.

15:09 <ehirdoy1> apache2: any way to get memory usage at runtime?

15:15 <apache2> yeah

15:16 <apache2> there's a bunch of stuff in the Gc module that you can use to pull information like that

15:19 <apache2> ehirdoy1: Gc.( (stat()).heap_words) maybe

15:21 <apache2> I don't know what this number represents, so you would have to look that up, but I think you can get a number like that. On top of that number is the size of whatever mappings your unikernel gets loaded with in memory (like the code and static data)

15:21 <apache2> you could probably look at the ELF binary with the `readelf` command, but it might be easier to inspect the binary while it's running in its native environment -- which backend are you targeting?

15:22 <apache2> and easier way again might also be to just do binary search, launching it a few times with various amounts of memory allocated and seeing when it stops crashing under casual load.
