Dimitris Rozakis	4510db20db	Always calculate linux used mem as total-(free+buffered+cache) ... Used memory was calculated as Total - Available. For newer kernels (3.14+), available memory is taken from /proc/meminfo, whereas for older kernels it is computed as free+buffered+cached. This commit changes that behavior. Available memory is still taken from /proc/meminfo, if available, but used memory is always computed as total-free-buffered-cached. This way, it matches the output of `free` for used memory (in the -/+ buffers/cache line) and other tools. Prior to this change, I'd see a reported used memory of 600MiB whereas free, htop and other tools would report a used memory of 1.8GiB. And adding used, cached, buffered and free memory would leave ~1.2GiB unaccounted for.	7 years ago

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.	7 years ago
Steven Hartland	d968f63e51	Eliminate call to swapinfo on FreeBSD ... Improve performance by eliminating the fork out to swapinfo on FreeBSD which also helps prevent crashes / hangs due to the outstanding fork crash bug: golang/go#15658 This also fixes the value reported by SwapMemory and SwapMemoryWithContext on FreeBSD which previously only included the first swap device and also reported the values in terms of 1K blocks instead of bytes.	7 years ago

Olivier Vielpeau	5b52fbbea5	[mem] Add commit-related stats to VirtualMemoryStat on Linux	7 years ago
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.	8 years ago

James Nugent	d19ac24a84	mem: Skip TestVirtual_memory on Solaris	8 years ago
James Nugent	b7760bb5a6	memory: Add basic Solaris VirtualMemory() support ... This commit adds support for VirtualMemory() in package mem. The support only extends to total memory capcity, since that is all that is required in Nomad. It does take into account global versus non-global zones, and does not use cgo. This has been tested inside a zone in the Joyent public cloud for a non-global zone, and in the global zone of a SmartOS virtual machine.	8 years ago

Marco Pfatschbacher	b4846b445b	Add support for OpenBSD/amd64 ... This code is based on the FreeBSD version and implements roughly the same feature set.	8 years ago
Luca Berruti	36f47562c0	Fix: wrong swap values on i686 / 4GB ram. ... According to sysinfo manpages: swap fields need to be interpreted along with the mem_unit (Unit) field. See also http://stackoverflow.com/a/4229727	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.	9 years ago

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	9 years ago

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.	9 years ago

Shirou WAKAYAMA	7288e9a5af	common[all]: add internal	10 years ago
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. Fixes #100	10 years ago
Jonathan Chauncey	0461c50666	chore(*): Fixes #94 ... Added the ability to fetch an alternative location for /proc via an environment variable. If the env var is not set it will return /proc as the default value.	10 years ago

Cameron Sparr	ce70817f55	Fix memory reporting for linux systems ... /proc/meminfo reports memory in KiloBytes and so needs a multiplier of 1024 instead of 1000. The kernel reports in terms of pages and the proc filesystem is left shifting by 2 for 4KB pages to get KB. Since this is a binary shift, Bytes will need to shift by 10 and so get multiplied by 1024. From the kernel code. PAGE_SHIFT = 12 for 4KB pages "MemTotal: %8lu kB\n", K(i.totalram) Thanks to @subhachandrachandra!	10 years ago
