DBAmon monitors the Transaction Logs (TLogs) of MSSQL databases.
It is controlled by the T_TLog_Full: DBC parameter. The default
is that this feature is ON for all MSSQL instances with thresholds
of 95/99. To turn it off, specify N for T_TLog_Full:.
How It Works:
If the TLog of a database is >= 90% full, then the following checks
are run:
If the TLog is set to LIMITED growth:
The size of the TLog is compared to the LIMIT. That percent
is compared to the T_TLog_Full: thresholds.
If the TLog is set to UNLIMITED growth:
The disk where the TLog resides is checked. That percent full value
is compared to the T_TLog_Full: thresholds.
