This image shows the Event microservice pipeline. It has the following components:

• On the left, an area representing the external network, containing:

  • Discovered devices

  • A UDP socket

  • An Apache Kafka bus

• On the right, a container representing Unified Assurance, containing:

  • A connection to the Device Discovery microservice pipeline

  • The Event database

  • Three microservice flows:

    • FCOM flow, containing the following microservices:

      • Collector microservices (Syslog, Trap, and others), reading from the generic discovered devices and publishing to the collection topic

      • Apache Pulsar, with topics for collection, forwarding, JavaScript, the event sink, and the event canal

      • RCA Availability Engine, reading from the Device Discovery Microservice Pipeline and publishing to the collection topic

      • FCOM Processor, reading from the collection topic and publishing to the forwarding, JavaScript, and event sink topics

      • Trap Forwarder, reading from the forwarding topic and connected to the UDP socket

      • JavaScript Generic Event Processor, reading from the JavaScript topic and publishing to the event sink topic

      • Event Sink, reading from the event sink topic and publishing to the Event database

      • Event Canal, reading from the Event database and publishing to the event canal topic

    • Non-FCOM flow, containing the following microservices:

      • Poller microservices (Ciena MCP, Cisco Meraki, and others), reading from discovered devices and publishing to the event sink topic

      • Apache Pulsar, with topics for the event sink and the event canal

      • Event Sink, reading from the event sink topic and publishing to the Event database

      • Event Canal, reading from the Event database and publishing to the event canal topic

    • TMF Flow, containing the following microservices:

      • Apache Pulsar, with topics for the event canal and TFM688

      • TMF 688 Event Processor, reading from the event canal topic and publishing to the TMF688 topic

      • Kafka Bridge, reading from the TMF688 topic and publishing to the external Kafka bus
