If enabling an EQL rule on a non-elastic-agent index (such as beats) for versions <8.2,
|
|
events will not define `event.ingested` and default fallback for EQL rules was not added until version 8.2.
|
|
Hence for this rule to work effectively, users will need to add a custom ingest pipeline to populate
|
|
`event.ingested` to @timestamp.
|
