Johan Walles 4438159155 Document + add tests for for mem.VirtualMemory()
This change changes and documents the (previously undocumented) behavior of Used
to "RAM used by programs".

We also remove the undocumented and unused Shared field of that struct.

So with this change in place, the VirtualMemoryStruct contains:
* three human-consumable fields for Total, Used and Available memory
* one human-consumable UsedPercentage field
* a number of kernel specific fields

Johan Walles 13e00c76e4 Use OS calls rather than exec() to get memory statistics
Before this change we used to exec() various binaries to find out memory
information.

While this worked, it was awfully slow.

And if somebody would want to compute how many percent of available memory all
PIDs on the system uses, that would take almost ten seconds on my laptop with
the previous implementation.

This implementation fares a lot better, and is smaller.

process: Implement MemoryPercent() for Darwin
9 years ago
Johan Walles 70444b571b process: Implement platform independent MemoryPercent()
It calls mem.VirtualMemory() and process.MemoryInfo(), so on the platforms where
those work MemoryPercent() will as well.

Tested on Darwin.

Johan Walles 09fbecef59 Darwin: Remove questionable UIDs
process.Process.uids is an array of undocumented values.

That one of them is the user that the process is running as is obvious, but what
the other two are supposed to be is AFAICT undocumented.

On Darwin, the second and third UID (out of three) seem to always be 0.

This change removes the two always-zero UIDs from the process.Process struct on
Darwin, and leaves just the one that actually identifies the user the process
is running as.

Make a public function for computing total CPU time
9 years ago
Johan Walles ebaa641e63 Make a public function for computing total CPU time
This function used to be a private part of process.go.

Since I needed that functionality however I think it's better to make it public
than for me to copy it into my own code.

As a side effect of this change, I also fixed a bug in the function where Stolen
was not part of the sum. Having the function close to the CPUTimesStat
declaration will make problems like this less likely to re-occur in the future.

try to fix diskio stats on FreeBSD-10.x
9 years ago
elij d1380cba29 try to fix diskio stats on FreeBSD-10.x
FreeBSD apparently changed the magic sysctl mib values for devstats.

    --- FAIL: TestDisk_io_counters (0.00s)
    disk_test.go:39: error no such file or directory
    disk_test.go:42: ret is empty, map[]

This code uses an undocumented, but exported, go stdlib method to fetch
the sysctl by string instead of mib.
