Consider SD-WAN as another example of DoH causing problems. The SD-WAN controller grants permission to connections based on the top-level domain (e.g., If Google has their druthers, a lot of SD-WAN vendors are going to be in a tough spot and will have to figure out another way to enforce policy. facebook.com) being visited.

The internet is now the critical glue that connects traditional and cloud infrastructure. In order to see and reason about the network, it’s critical to gather telemetry: From all networks (cloud, data center, WAN, SD-WAN, internet, mobile, branch, and edge).

KDE handles over 10B flow records/day with a microservice architecture that's optimized using metrics. And that leads us to metrics. Health checks and series metrics. Graphed, time series metrics make obvious at a glance if new code is helping. To dig deeper and get useful numbers, we need metrics reporting over time.

Synthetic testing is done by sending synthesized tests that are not from real users to check availability and performance metrics, such as latency, jitter and packet loss. In order to be effective for the modern, internet-centric and orchestrated era, a synthetic monitoring solution must have: No blind spots. What is synthetic testing?

This could mean the users are saturating the internet connectivity or that they’ve saturated the LAN (or maybe WAN). When configuring traffic sources, the flow data is sent directly to Kentik over the internet, or it can go through kProxy, a Kentik client that encrypts the flow or Syslog data before sending it over the internet.

Managing peering, interconnection, and the overall state of traffic crossing the network edge to and from other networks is critical for any organization doing business on the internet.

For AWS cloud networks, the Transit Gateway provides a way to route traffic to and from VPCs, regions, VPNs, Direct Connect, SD-WANs, etc. Entry point for on-premises SD-WAN connections. Cloud architects and network engineers can interact directly on the map to view hop by hop, metrics, and details on traffic, routing, and metadata.

Monitoring needs to span multiple domains: the private enterprise data center and WAN; fixed and mobile service provider networks; the public Internet; and hybrid multi-cloud infrastructure. Performance metrics and other types of monitoring data can be collected in real time using streaming telemetry protocols such as gRPC.

Send these pings using the Internet Control Message Protocol (ICMP) or TCP to one or any of the devices you believe to be involved. Ping and traceroute tests performed continuously with public and/or private agents generate key metrics (latency, jitter, and loss) that are evaluated for network health and performance.

Until just a few years ago, enterprise networks were predominantly comprised solely of one or more private data centers connected to a series of campuses and branch offices by a private WAN that was based on MPLS VPN technology from a major telecom carrier. The effect on network traffic is profound. But cloud realities break that assumption.

So NPM is about another set of metrics. Metrics such as round-trip time, out-of-order packets, retransmits, and fragments, tell you how well the network is doing its job. And this makes it hard to know if you have the metrics and measurements that you need. NPM Architectures. Three NPM challenges.
