Message Broker Service Level Agreement

Service Name(s)

Message Broker


This service allows short, text based messages to be exchanged between OSG operated computers. Uses include transport of accounting information to GRACC and network performance metrics to perfsonar. Service subscribers access queues to exchange data using point-to-point or publish and subscribe patterns. See the Wikipedia article on message queueing services for further discussion.

The OSG uses a commercial vendor which provides their own SLA. However, their SLA does not cover "overuse of resources," which is a common reason for downtime of the message broker.
