![]() ![]() crcSalt is a string added to the calculation of the initial CRC to help with reindexing files. The thought is as you roll a log file, most of the time you do not want to reindex the file's contents. How this works is that Splunk doesn't use filenames by default to track files, but instead calculates a cyclic redundancy check on the first 256 bytes (default controlled by initCrcLength) of the file as an identifier for the file. Then complete the workflow above, using the exported files instead of original sample files.Be careful! Attributes in splunk config files are case sensitive! Therefore the correct entry to add to each stanza in nf that you want to reindex upon rename is actually: crcSalt = If your data is in Elastic or Splunk, and you can neither capture live nor obtain original samples, use one of the following export procedures. Archive the directory (e.g., with a command like tar -czf samples.tgz samples) for portability send it to your Cribl representative, if you are working with one.Redact sensitive content in the data, if required.Add a README file to the directory, as described above.Repeat until all desired sample files have been copied.Copy a sample file into the new directory.Create a directory in which to store samples. ![]() If live-capturing data with Cribl Stream is impractical for you, gather sample files that the sending agent has not yet processed, using the following general workflow:
