I am a contractor for USPS. My role is project manager for IV and I am writing a paper on Splunk. The diagrams list "OAP Splunk Architecture Diagram". For the life of me I cannot find out what "OAP" stands for....
This is most likely a reference to an internal platform or team that owns the Splunk infrastructure at your company. You should, if you havent already, check with your Platform Team.
Could it mean Over The Air Programming
, a pradigm wherein communication happens from a central location to all peers.
