To do this
Number of minutes that records must overlap
Type the number of minutes that records must overlap. The default overlap is 30 minutes.
If overlap is detected
Select an action to take if an overlap is detected:
Import all records. Imports all requests, including overlapping requests.
Stop the import. Does not import the log file if overlapping requests are detected.
Stop all imports. Stops all log file imports if overlapping requests are detected.
Discard records and proceed (default). Discards all overlapping requests and imports the remaining requests.
When import is completed
Select an action to take with the open visits at the end of your import process:
Store open visits for the next import (default setting). Reconstructs the actual visit as if there were one seamless log file. This option takes slightly more time because the open visits must be called up from the cache at each new import. You must import log files in chronological order for this option to work correctly.
Commit open visits to database. The visit count will be higher at the opening and closing of the log file period because visits that span those two periods will be counted twice.
Discard open visits. The report count will be lower at the closing of the log file period because visits that have not been closed will be dropped.
