Log File Rotation

[snapfinger]

When splunk is watching a directory for log files will it reindex a file that gets rotated? I am trying to make sure that some of my logs are not getting indexed twice.

Example:

file1.log gets changed to file1.log12212010 service creates new file1.log and continues logging.

It will not reindex your file. Splunk will not do this by default. Normally, it identifies a file using a hash of the first 256 bytes of the file content, and not the file path/name. (This can be overridden.) However, do note that if you rename and compress the file, it will be reindexed, but you can suppress this by blacklisting compressed files by the name.
