So I am not a modern kernel dev. That being said, I currently data over time

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

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 
        iflib   813  6241K      833 
      solaris   113 18692K      233 
   md_sectors  7260 29040K     7260  4096
       devbuf 28312 46705K    35453 
      pf_hash     5 51204K        5  2048
         Type InUse MemUse Requests  Size(s)

Does this help any?
