Description

### Question

"Version": `v1.6`

1. The Chinese explanation for the 'Connections' field in the MySQL monitoring template seems to be incorrect

2. Then, I want to set the rule '${threads_connected} >=({max_connections}*0.9)'. Is this rule available and feasible, considering that these two data points are located on different tabs?

Research direction

Start with the MySQL server-status variables documentation linked in the issue, then inspect the MySQL monitoring template and monitor-rule evaluation for how the Connections field and variables from different tabs are handled. Done means confirming or correcting the Chinese explanation and documenting whether the proposed cross-tab comparison is supported.
