Cool - just changed to use ErrnoError().
I'll commit this patch if you do not have any further comments.

getloadavg is most likely just a wrapper for sysctl (which sets errno), so yes - should probably be ErrnoError.
I will get this in the new patch.

Having both sounds good, just want to make sure we have cpu time as well, so that we can detect CPU consumption spikes in the Master :)

If I understand correctly, get and aggregate cpu times for the master's process tree instead?
I think that is valuable too and we could totally do that, but I still think the system load average is a good indicator (and well-known convention) of the general machine load.
Can overcommitment be detected from the cpu time? AFAIK, you get from cpu time to cpu usage % from the fraction (cpu time / measured total time) which is at most 1. The load average is based on the process queue length, which along with the number of cores captures overcommitment.
I might be totally off - maybe there is a good reason for having both?
Thoughts?

Hey Nik, I see your gist here:
https://gist.github.com/nqn/7493244
More interesting than node-wide load average will be the total cpu time for the master, can we expose the same cpu time information as what we do in ProcessIsolator::usage instead of the load average?
