slabtop displays detailed kernel slab cache information in real time. It displays a
listing of the top caches sorted by one of the listed sort criteria. It also
displays a statistics header filled with slab layer information.
The following are valid sort criteria used to sort the individual slab caches
and thereby determine what are the "top" slab caches to display. The default
sort criteria is to sort by the number of objects ("o").
The sort criteria can also be changed while slabtop is running by pressing
the associated character.
slabtop requires a 2.4 or later kernel (specifically, a version 1.1 or later
/proc/slabinfo). Kernel 2.2 should be supported in the future.
The slabtop statistic header is tracking how many bytes of slabs are being
used and it not a measure of physical memory. The Slab field in the
/proc/meminfo file is tracking information about used slab physical memory.
