The document describes VNS3's software-only virtual appliance that creates a secure, distributed, monitored layer 3 overlay network across multiple regions and clouds. It details the functionality of VNS3's plugin system, including the integration of Datadog for monitoring, which allows for real-time health checks and alerts of the network. Additionally, it illustrates the topology of the network and the various services that can be provided through the system.
Bob Smetana's talk "Monitoring VNS3 infrastructure health and status with DataDog"
- 1. Using VNS3’s plugin system and Datadog to create a secure, distributed, monitored layer 3 network @ Bob Smetana Network Solutions Architect
- 2. Who we are / what we do 2 software-only virtual appliance
- 3. Who we are / what we do 3 VNS3 provides an flat, encrypted, overlay network which can be spread across multiple regions and clouds. This network is entirely yours, and provides a layer of separation between the hypervisor and your layer3 network. Management of distributed applications’ networks becomes easy to understand and implement.

- 6. Example: DataDog monitoring plugin 6 • Hosts the DataDog agent • Gathers information via SNMP and the VNS3 API • Reports custom metrics to DataDog • Offers users an “at-a-glance” overview of overlay network and appliance health • Alerts can be configured based on predefined conditions or abnormal statistics • Can predict network issues so that proactive action can be taken
