Table 56: show system virtual-memory Output Fields

Field Name Field Description
Memory statistics by bucket size
Size Memory block size (bytes). The kernel memory allocator appropriates blocks of memory whose size
is exactly a power of 2.
Number of memory blocks of this size that are in use (bytes).
In Use
Number of memory blocks of this size that are free (bytes).
Free
Number of memory allocation requests made.
Requests
Maximum value the free list can have. Once the system starts reclaiming physical memory, it continues
HighWater
until the free list is increased to this value.
Couldfree Total number of times that the free elements for a bucket size exceed the high-water mark for that
bucket size.
Memory usage type by bucket size
Size Memory block size (bytes).
Kernel modules that are using these memory blocks. For a definition of each type, refer to a FreeBSD
Type(s)
book.
Memory statistics by type
Kernel module that is using dynamic memory.
Type
Number of memory blocks used by this type. The number is rounded up.
InUse
Amount of memory in use, in kilobytes (KB).
MemUse
Maximum memory ever used by this type.
HighUse
Maximum memory that can be allocated to this type.
Limit
Total number of dynamic memory allocation requests this type has made.
Requests
Number of times requests were blocked for reaching the maximum limit.
Type Limit
Number of times requests were blocked for kernel map.
Kern Limit
Memory block sizes this type is using.
Size(s)
Memory Totals
In Use Total kernel dynamic memory in use (bytes, rounded up).
Total kernel dynamic memory free (bytes, rounded up).
