Hello,
I updated mysqltuner to newer version, I already use mysql tuner from a long time ago, previously I used version 2018 :(
But when I updated and running newer version got error
Use of uninitialized value $mystat{"Table_open_cache_hits"} in multiplication
(*) at ./mysqltuner.pl line 2745 (#1)
what value of my config can adjust?
Thanks for your support
