ID: 4436 Title: check_sql: fixed thresholds and added missing options Component: Checks & agents Level: 1 Class: Bug fix Version: 1.5.0i1 Thresholds are now actually used when the options are activated and the number is added to the output if Thresholds are set. Additionally the option "Performance Data" is now actually used. If not activated no performance data will be added, even if it is given by the result of the SQL statement.
