Add the Luna custom-token option to a Splunk Agent Observability environment with Cisco E3A-SK-SAO-LIC-LA. This EA3 application add-on license is associated with Splunk Agent Observability and is specifically designated for the Luna custom-token option. It addresses an entitlement requirement within the observability service rather than adding a physical network, compute, or monitoring appliance. The add-on designation matters when matching the license to an existing service configuration. E3A-SK-SAO-LIC-LA is not described as a base observability subscription or a general-purpose software package; it is the Luna custom-token add-on. Administrators should match the required Luna custom-token option and existing Splunk Agent Observability service scope before assigning the entitlement. Cisco uses E3A-SK-SAO-LIC as the underlying model designation, while the -LA form identifies the orderable code. Both references point to the same product. Its distinguishing characteristic within the EA3 application range is the explicit connection to Splunk Agent Observability and the Luna custom-token option, helping separate it from licenses intended for other applications, services, or entitlement functions.
