In a PubSub model, any message published to a topic is immediately received by all of the subscribers to the topic. PubSub messaging can be used to enable event-driven architectures, or to decouple applications to increase performance, reliability and scalability.

Use the OpsRamp Google public cloud integration to discover and collect metrics against the Google service.

Setup

To set up the OpsRamp Google integration and discover the Google service, go to Google Integration Discovery Profile and select Topic.
