Network traces are stored in hundreds of binary files in a directory.
How do I upload those files (they won't get updated)?
In the Splunk settings, I saw how to upload a single script- but not a full directory.
I'm using a single instance.
Splunk supports ingesting ASCII / human-readable data. You could technically ingest the files, but it really wouldn't be anything understandable. If there is a way to convert the binary to ASCII, then you could use a scripted input to run a script against the binaries. The script could dump the ASCII output to a directory which you could then monitor.
As for monitoring a whole directory, take a look at the docs here: https://docs.splunk.com/Documentation/Splunk/7.2.6/Data/Monitorfilesanddirectorieswithinputs.conf
I no longer need to use those binary files, so I'm accepting the below answer to close the question.
