When the Log appears in your browser window, all Log records are displayed. Since Logs can have thousands of records, you may want to view only a portion of the Log. Interrupt the Log downloading process and specify the Log Level and the Time Interval options:
Only the records with time stamps in the specified interval are displayed.
If you are viewing the current Log and specify "*" in the second field, all records placed in the Log by this moment are displayed.
If you are viewing the current Log and specify some future time in the second field, the Server will keep the browser channel open, sending new Log records as they are placed in the Log. The channel is closed either at the end of the specified Time Interval, or when the Server starts a new Log.
