fix logic error + little refactor 
Fix: get cptime of n-th cpu when `percpu` instead of the average.

While there, rearrange the last if statement to make the code a bit
more homogeneous.

Laurie Clark-Michalek 413cb32b6c Use static initialisation for invoke instances, instead of init funcs 
The order of init function execution is dependant on the order that the
source files are passed to the compiler. This causes issues when
building under other build systems, such as bazel or buck, as they are
not guarenteed to maintain the same file order as the default go tool.

Steven Hartland 6450c60b61 Eliminate use of sysctl command on FreeBSD 
In order to improve performance and help prevent crashes due to the outstanding fork crash bug:
https://github.com/golang/go/issues/15658

Replace string parsed values from the sysctl command with native reads of sysctl values using unix.SysctlRaw and unix.SysctlUint32.

This also merges OpenBSD and FreeBSD load implementations which are identical.

cpu: Implement Solaris support for Info()
 8 years ago
James Nugent 49ed700c0d cpu: Implement Solaris support for Info() 
This commit adds Solaris(^1) support for the Info() function of package
cpu, with the exception of the L2 cache size which is not trivially
available(^2).

Support is implemented by parsing the output of `isainfo -b -v` (for the
instruction set flags), and `psr-info -p -v` for other information.
Example outputs from a range of different size VMs and Joyent containers
are included as part of the tests.

(^1): This has only been tested with Illumos in the form of SmartOS. I
believe it to be portable to other Illumos distributions but have not
tested on Oracle Solaris.

(^2): Enough support is added here to be usable for my port of
HashiCorp's Nomad to SmartOS.

Breno Leitao 286927a039 Improve CPU identification for POWER processors 
Currently gopsutils fails to indentify the POWER processors family,
returning an almost empty Info() structure.

This patch improves the POWER identification without changing what is
available for x86.

K.C. Wong 3dc4e52844 Handle the case when the `cpufreq` sysfs does not exist 
* on virtualized host, this may happen.
* but we may have a value from parsing `/proc/cpuinfo`
* in this case, we do not return the error if we fail to extra
  a value from `cpufreq/cpuinfo_max_freq`
 9 years ago
K.C. Wong 10a1ae2123 Standardize `Mhz` to mean maximum CPU frequency on Linux platform 
* resolve #249
* in `cpu_windows.go`, `Mhz` is the value of `MaxClockSpeed`
* on Linux platform, the `Mhz` value is extracted from `/proc/cpuinfo`
  which reflects the current clock speed; treat this as the fallback
  value instead
* read from `cpufreq/cpuinfo_max_freq` under sysfs to get the
  maximum clock speed for `Mhz`, just like for Windows platform
* also fix the path to `cpu.CoreID` value; the filename is `core_id`

shirou a8e24d70f9 Merge pull request #247 from lfittl/fallback-for-unsupported-architectures 
Add fallback code for all unsupported operating systems
 9 years ago
K.C. Wong 123a6c9b0d Addressing frequency unit discrepancies 
* for Darwin, it is a minor tweak for readability: the value
  returned is in Hz, so using a variable named 'hz' makes more
  sense than 'mhz'
* for Linux, the unit is in kHz so we need to divide the value
  from `cpuinfo_max_freq` by 10^3 to get MHz (see
  cpu-freq/user-guide.txt of the kernel documentation)
 9 years ago
Lukas Fittl da9fa1162b Add fallback code for all unsupported operating systems. 
This enables using gopsutil in a codebase that gets built on other OSes
than the ones supported. Instead of a build failure as before, due to
the build tags, gopsutil will now throw an "not implemented" runtime
error.

Fixes #234.

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.

Daniel Theophanes 0af895258e common: rename package common to internal/common. Add ENV helper funcs. 
Package common wasn't used for public functions. Place it in an
internal directory to prevent other packages from using.

Remove the distributed references to "HOST_PROC" and "HOST_SYS"
consts and combine into a common function. This also helps so that
if a env var is defined with a trailing slash all will continue to
work as expected.
