--- Comment #2 from Dave Hayes <dave@jetcafe.org> ---
So I am not a modern kernel dev. That being said, I currently data over time
of:

- anything in sysctl=20
- vmstat -z ... malloc buckets and UMA=20

I can fairly easily monitor almost any other value I can get with a command=
, I
just need to know what to monitor exactly (*all* of vmstat -m or vmstat -z =
is
probably not indicated and a waste of prometheus space).

Now having said that, I did this:

# vmstat -m | sort -k 3
...
      bus-sc   139  5134K    12172=20
16,32,64,128,256,384,512,1024,2048,4096,8192,16384,32768,65536
        iflib   813  6241K      833=20
16,64,128,512,1024,2048,8192,16384,32768,65536
      solaris   113 18692K      233=20
16,32,64,128,256,512,1024,2048,4096,8192,65536
   md_sectors  7260 29040K     7260  4096
       devbuf 28312 46705K    35453=20
16,32,64,128,256,384,1024,2048,4096,8192,65536
      pf_hash     5 51204K        5  2048
         Type InUse MemUse Requests  Size(s)

Does this help any?
