+@ kernel.all.pswitch context switches metric from /proc/stat
+@ kernel.all.sysfork fork rate metric from /proc/stat
+@ kernel.all.intr intrrupt rate metric from /proc/stat
+The value is the first value from the intr field in /proc/stat,
+which is a counter of the total number of interrupts processed.
+The value is normally converted to a rate (count/second).
+This counter usually increases by at least HZ/second,
+i.e. the clock interrupt rate, wehich is usually 100/second.
+
+See also kernel.percpu.interrupts to get a breakdown
+of interrupt rates by interrupt type and which CPU
+processed each one.
+
+@ mem.physmem total system memory metric reported by /proc/meminfo
+The value of this metric corresponds to the "MemTotal" field
+reported by /proc/meminfo. Note that this does not necessarily
+correspond to actual installed physical memory - there may
+be areas of the physical address space mapped as ROM in
+various peripheral devices and the bios may be mirroring
+certain ROMs in RAM.
+@ mem.freemem free system memory metric from /proc/meminfo
+@ mem.util.used used memory metric from /proc/meminfo
+Used memory is the difference between mem.physmem and mem.freemem.
+@ mem.util.free free memory metric from /proc/meminfo
+Alias for mem.freemem.
+@ mem.util.available available memory from /proc/meminfo
+The amount of memory that is available for a new workload,
+without pushing the system into swap. Estimated from MemFree,
+Active(file), Inactive(file), and SReclaimable, as well as the "low"
+watermarks from /proc/zoneinfo.
+
+@ mem.util.shared shared memory metric from /proc/meminfo
+Shared memory metric. Currently always zero on Linux 2.4 kernels
+and has been removed from 2.6 kernels.
+@ mem.util.bufmem I/O buffers metric from /proc/meminfo
+Memory allocated for buffer_heads.
+@ mem.util.cached page cache metric from /proc/meminfo
+Memory used by the page cache, including buffered file data.
+This is in-memory cache for files read from the disk (the pagecache)
+but doesn't include SwapCached.
+@ mem.util.other unaccounted memory
+Memory that is not free (i.e. has been referenced) and is not cached.
+mem.physmem - mem.util.free - mem.util.cached - mem.util.buffers
+@ mem.util.active Kbytes on the active page list (recently referenced pages)
+Memory that has been used more recently and usually not reclaimed unless
+absolutely necessary.
+@ mem.util.inactive Kbytes on the inactive page list (candidates for discarding)
+Memory which has been less recently used.  It is more eligible to be
+reclaimed for other purposes
+@ mem.util.swapCached Kbytes in swap cache, from /proc/meminfo
+Memory that once was swapped out, is swapped back in but still also
+is in the swapfile (if memory is needed it doesn't need to be swapped
+out AGAIN because it is already in the swapfile. This saves I/O)
+@ mem.util.highTotal Kbytes in high memory, from /proc/meminfo
+This is apparently an i386 specific metric, and seems to be always zero
+on ia64 architecture (and possibly others). On i386 arch (at least),
+highmem is all memory above ~860MB of physical memory. Highmem areas
+are for use by userspace programs, or for the pagecache. The kernel
+must use tricks to access this memory, making it slower to access
+than lowmem.
+@ mem.util.highFree Kbytes free high memory, from /proc/meminfo
+See mem.util.highTotal. Not used on ia64 arch (and possibly others).
+@ mem.util.lowTotal Kbytes in low memory total, from /proc/meminfo
+Lowmem is memory which can be used for everything that highmem can be
+used for, but it is also availble for the kernel's use for its own
+data structures. Among many other things, it is where everything
+from the Slab is allocated.  Bad things happen when you're out of lowmem.
+(this may only be true on i386 architectures).
+@ mem.util.lowFree Kbytes free low memory, from /proc/meminfo
+See mem.util.lowTotal
+@ mem.util.swapTotal Kbytes swap, from /proc/meminfo
+total amount of swap space available
+@ mem.util.swapFree Kbytes free swap, from /proc/meminfo
+Memory which has been evicted from RAM, and is temporarily on the disk
+@ mem.util.dirty Kbytes in dirty pages, from /proc/meminfo
+Memory which is waiting to get written back to the disk
+@ mem.util.writeback Kbytes in writeback pages, from /proc/meminfo
+Memory which is actively being written back to the disk
+@ mem.util.mapped Kbytes in mapped pages, from /proc/meminfo
+files which have been mmaped, such as libraries
+@ mem.util.slab Kbytes in slab memory, from /proc/meminfo
+in-kernel data structures cache
+@ mem.util.commitLimit Kbytes limit for address space commit, from /proc/meminfo
+The static total, in Kbytes, available for commitment to address 
+spaces. Thus, mem.util.committed_AS may range up to this total. Normally 
+the kernel overcommits memory, so this value may exceed mem.physmem
+@ mem.util.committed_AS Kbytes committed to address spaces, from /proc/meminfo
+An estimate of how much RAM you would need to make a 99.99% guarantee
+that there never is OOM (out of memory) for this workload. Normally
+the kernel will overcommit memory. That means, say you do a 1GB malloc,
+nothing happens, really. Only when you start USING that malloc memory
+you will get real memory on demand, and just as much as you use.
+@ mem.util.pageTables Kbytes in kernel page tables, from /proc/meminfo
+@ mem.util.reverseMaps Kbytes in reverse mapped pages, from /proc/meminfo
+@ mem.util.cache_clean Kbytes cached and not dirty or writeback, derived from /proc/meminfo
