Basically all the info you need is in os.hpp in the stout lib of mesos. Effectively, the cpus are just a syscall:
sysconf(_SC_NPROCESSORS_ONLN); The memory on the other hand is calculated: # if LINUX_VERSION_CODE >= KERNEL_VERSION(2, 3, 23) memory.total = Bytes(info.totalram * info.mem_unit); memory.free = Bytes(info.freeram * info.mem_unit); # else memory.total = Bytes(info.totalram); memory.free = Bytes(info.freeram); # endif On Thu, May 21, 2015 at 6:51 AM, Aaron Carey <[email protected]> wrote: > I've managed to increase the disksize by playing with some docker > options, > > Anyone have any idea about the memory? > > Thanks, > Aaron > > ------------------------------ > *From:* Aaron Carey [[email protected]] > *Sent:* 21 May 2015 11:19 > *To:* [email protected] > *Subject:* How slaves calculate resources > > Hi, > > I was just trying to figure out how Mesos slaves report the amount of > resources available to them on the host? > > We have some slaves running on AWS t2.medium machines (2cpu, 4Gb RAM) with > 32GB disks. > > The slaves are running inside docker containers. > > They report 2 cpus (correct), 2.5GB RAM and 4.9GB disk. > > Any ideas why this is different from what I can see on the machine?
