Understanding Field Mapping Requirements

When creating field mappings, there are some requirements to be aware of.

  • Neither the alias nor the source field can start with # or @, like #kind or @timestamp. These are Metadata Fields with special meaning in LogScale.

  • All aliases must be unique.

  • The tag conditions cannot be conflicting. For example, it is not possible to have both #vendor=A and #vendor=B as conditions on the same mapping. More details on tag conditions are described in Understanding Schema Requirements.
