Is it necessary to optimize logs in Splunk?
Optimizing your logs at the source is not necessary or required, but it can streamline your Splunk experience. Optimizing event logs makes the most sense for systems in active use whose source code is easily accessible. It may not be practical to try rewriting the logs for a legacy application whose source code is no longer available. A better approach in that case is to use Splunk knowledge objects to add meaning to existing log information.
How does Splunk work?
The Splunk platform uses this CRC to look up an entry in a database that contains all the beginning CRCs of files that it has seen before. If it finds a match in this database, the lookup returns a few values about the file. The most important values are the seekAddress, which represents the number of bytes into the known file that the Splunk platform already read, and the seekCRC, which is a fingerprint of the data at that location.
Can Splunk categorize files?
Using the results of this lookup, the Splunk platform can categorize the file.
Does Splunk read a file?
