Hi team, I’m configuring a Cribl File Monitor source to ingest multiple files under the same path, but it looks like only the first file in the list is actually being ingested. Has anyone run into this behaviour before? Max Depth is unlimited.

Have you confirmed the hash header is different between the files? I think default is the first 256 bytes. You will have to increase it until the hash header is unique

Under advanced you can also choose to "salt file hash". This will consider the filename in the creation of the hash. IF the filename is always unique, that could help. If filenames are repeated move along to increasing the has length
