The CommuniGate Pro Logs can be very big, reaching several hundred megabytes of data on a heavily loaded Server or on a Server with low-level logging enabled. It is difficult to examine an entire Log of that size.
Use this setting to suppress displaying records that are more detailed than the specified value (have a higher level marker).
Use this option to specify the Filter string. Only the records containing this string will be displayed. The first part of log records (including a time stamp and a level marker) is not used for filtering operations.
If this option is selected, the Filter string is interpreted as a regular expression.
Click the Display button to display only the records that contain the specified substring.
Some of your users complain that sometimes their mailer application cannot retrieve messages from your server properly and that they see error messages informing them about some protocol errors.
Since it does not occur often, you should run the IMAP module with its Log Level set to All-Info, though this will make your Logs very big. Finally, a user contacts you and says that the mailer has just displayed the same error.
You open the Log and set the Level to 3 (Problems). Now you may see all the problems with the IMAP module that occurred today. When you find the record that indicates the problem your user is talking about, you see that that record has the IMAP-437425 tag. So, you type IMAP-437425 into the Filter field, and change the Log Level to 5 (All Info). As a result, you see a clean log of that particular IMAP session.
