Meminfo

Simple go package that return the out put of the /proc/meminfo file as a go struct.

How to use ?

There is one function NewMeminfo() (Meminfo, error) that return you a new Meminfo struct and possible errors.

The Meminfo struct represent what the /proc/meminfo file give you.

How it work ?

The program will read the file /proc/meminfo.

Exemple of what contain the /proc/meminfo file:

MemTotal:        7845016 kB

Then the program convert it as a struct like this (this not result of the previous file):

Meminfo{
    MemTotal:          16585088,
    MemFree:           10162564,
    Buffers:           34032,

    SwapTotal:         14569852,
    SwapFree:          14340140,

    Writeback:         0,
    AnonPages:         102824,
    Mapped:            71404,
    Shmem:             17720,
    Slab:              13868,
    SReclaimable:      6744,
    SUnreclaim:        7124,
    KernelStack:       2848,
    PageTables:        2524,
    NFS_Unstable:      0,
    Bounce:            0,
    WritebackTmp:      0,
    CommitLimit:       515524,
    Committed_AS:      3450064,
    VmallocTotal:      122880,
    VmallocUsed:       21296,
    VmallocChunk:      66044,
    HardwareCorrupted: 0,
    AnonHugePages:     2048,
    HugePages_Total:   0,
    HugePages_Free:    0,
    HugePages_Rsvd:    0,
    HugePages_Surp:    0,
    Hugepagesize:      2048,
    DirectMap4k:       12280,
    DirectMap2M:       897024,
}

Then you can use this struct as you want.
