/* The memory available field is describe in /proc man page as :

* "An estimate of how much memory is available for starting new applications, without swapping."

* We can see in page_alloc.c in the linux kernel that :
|
||||
* "Not all the page cache can be freed, otherwise the system will start swapping.
|
||||
* Assume at least half of the page cache, or the low watermark worth of cache, needs to stay."
|
||||
* There is a difference between the system starts swapping and OOM happens even if there is no swap
|
||||
* on the system.
|
||||
* People think they will find the same amount of used RAM with the free program.
|
||||
* From man free, we can see :
|
||||
* used Used memory (calculated as total - free - buffers - cache)
|
||||
* free Unused memory (MemFree and SwapFree in /proc/meminfo)
|
||||
* buffers Memory used by kernel buffers (Buffers in /proc/meminfo)
|
||||
* cache Memory used by the page cache and slabs (Cached and SReclaimable in /proc/meminfo)
|
||||
* So, curmem should be calculate as follow to find the same amount of memory in conky and free.
