is the capacity of a system of generating random numbers. The Entropy increases during Input/Output operations.
- for example from /dev/urandom
- to check the available amount of entropy:
cat /proc/sys/kernel/random/entropy_avail
- this shows a server that run out of entropy due to a I/O driver failure, this caused no I/O to any device and consequently no entropy
