I have recently upgraded to Ubuntu 20.04 and after upgrade the charts are not showing I am seeing the following in openhab.log: Unknown system variable ‘tx_isolation’
I’m using MySQL v8 on Linux
I found a reference to say this variable is obsolete in Mysql 8
18
If you are using MYSQL8, try to show variables like 'transaction_isolation'. Mysql8 has renamed tx_isolation to transaction_isolation.
