Measures reported by IfxLogicalLogTest
The logical logs are one of the most important resources of the database server. Your database server will be blocked if they become full because they could not be backed up. You might also lose transactions in the case of a failure, if your logical logs have not been backed up. Thus, observing the behaviour of the logical logs is essential. This test collects and reports measures related to the logical logs.
The measures made by this test are as
