I use PHP Version 7.0.12-1~dotdeb+8.1 and mysqlnd 5.0.12-dev on Debian 8. I am running several WordPress 4.6.1 sites .
I have enabled statistics for mysqlnd and according to php.info() it is actually enabled:
- Collecting statistics Yes
- Collecting memory statistics Yes
But the section "mysqlnd statistics" is always empty. Only zeros. What could be the reason of a zero statistics for mysqlnd? How to turn it on?
