Network Monitoring

With Datadog NPM, we can quickly determine if our network is at fault for slow traffic or low connectivity before our applications are affected, so that insuring travel is a seamless experience for our customers.

Lead Architect at Generali Global Assistance

Maintaining performant service communication is critical to ensuring that our customers are able to best support their customers through our platform, so we needed a way to detect when DNS issues occurred—quickly and reliably.

Vicente De Luca

Principal Engineer at Zendesk

We really like how Datadog's NPM product is tied into the rest of the platform. Being able to monitor network traffic all the way down to our containers with Datadog has helped us identify improvements and optimizations across our platform.

Brent Montague

Principal SRE at Cvent

Datadog NPM gave us immediate visibility into all our Kubernetes cluster traffic. As soon as a new cluster is spun up, we can see if pods are communicating as expected and if internal DNS is doing its job.

Network monitoring with Datadog provides full visibility into every layer of your cloud, on-premise, or hybrid environment. Network Performance Monitoring lets you monitor your network architecture alongside application, infrastructure, and DNS performance for faster troubleshooting. Network Device Monitoring provides insight into the health and performance of bare-metal devices such as routers, firewalls, and switches.

Live network mapping and analysis with Network Performance Monitoring

Analyze traffic as it flows across applications, containers, availability zones, and on-premise servers
Identify cross-pod communication issues and troubleshoot inefficient load balancing
Pinpoint the services and teams responsible for abnormal spikes in traffic

Inspect a service on the network map to isolate up and downstream dependencies

Analyze network traffic between meaningful endpoints—not just IPs

Monitor the health of traffic between any two endpoints at the app, IP, port, and PID layers
View communication between services, pods, cloud regions, and cloud resources
Track key network metrics like TCP retransmits, latency, and connection churn

Network connections between services and pods

Deep visibility into DNS performance

Analyze system-wide DNS performance without having to SSH into individual machines
Assess DNS server health with request volume, response time, and error code metrics
Differentiate between client-side code errors and server-side DNS failures

DNS requests from an ad-server service to DNS servers

Health and performance insights into any on-premise device with Network Device Monitoring

Autodiscover any device on any network or subnet, with support for brands like Cisco, HP, Dell, F5, Juniper, and more
Aggregate metrics across all devices by location—and quickly drill down to view the health of specific interfaces
Proactively monitor device health with machine learning–based alerts; forecast bandwidth utilization and get alerted before problems arise
