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

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.

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

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
