Symantec Messaging Gateway includes an enhanced logging feature that allows system administrators to enable alerts when logging disk space on Scanners nears or reaches capacity. When the default threshold levels are reached, the system shifts to a reduced or halted logging mode and sends an email notification to the specified administrator. You will need to enable the low disk space alerts to receive this notification.
A logging mode change is typically caused by a change in log levels in the Control Center. If an administrator sets the log level to a level that yields a high volume of data (such as the Debug level), the Control Center may not be able to copy data files from the Scanner to the log database at a rate that keeps pace with the incoming data feeds. Log files remain on the Scanner and disk space quickly fills up.
When the system shifts to reduced logging mode, only urgent log levels (e.g., Errors and Warnings) are recorded. Log levels that produce excess data of a non-urgent nature (e.g., Notices, Information, and Debug) are suspended until space is freed on the disk. When a halted situation occurs, all log levels are suspended. Normal logging resumes only after the log files have been transferred off the disk.
Reduced and halted logging only applies to appliances operating as a Scanner or Directory Data Service (DDS).
