The official template 'Template DB MSSQL' contains triggers that will never resolve.

For example: Rate of log shrinks

It uses the trigger expression {TEMPLATE_NAME:mssql.db.log_shrinks["

"}

The item mssql.db.log_shrinks however measures total shrinks (since SQL server startup). This is a number that will not decrease while the server is running. Therefore, once triggered it will not resolve until SQL server is restarted. There is no conversion to a shrink rate.

To have a shrink rate trigger there would be some sort of delta to compare against.
