Latency numbers every programmer should know

L1 cache reference ......................... 0.5 ns
Branch mispredict ............................ 5 ns
L2 cache reference ........................... 7 ns
Mutex lock/unlock ........................... 25 ns
Main memory reference ...................... 100 ns             
Compress 1K bytes with Zippy ............. 3,000 ns  =   3 µs
Send 2K bytes over 1 Gbps network ....... 20,000 ns  =  20 µs
SSD random read ........................ 150,000 ns  = 150 µs

Read 1 MB sequentially from memory ..... 250,000 ns = 250 µs

* Shows a message while asserting like: 

ok: [host] => {                  
    "msg": "disk usage 4.2B of total 20.0GB (21.0%) (should exceed limit 90.0%)"
}

* Note this only looks at first mount point on current node
* Fails if disk is near-full
* Last step pushes to a push-based monitoring service, which will alert us if it doesn't get there after some time
* Need to setup a  variable `disk_limit`, which is the max acceptable usage ratio, e.g. set it to 0.8 if you want to keep disks within 80% of max size
