Datadog Network Monitoring

Act on real-time network insights

• Monitor the health of traffic between any two endpoints at the app, IP address, port, or process ID (PID) layers.
• Track key network metrics, such as TCP retransmits, latency, and connection churn.
• Use visualizations of network traffic across applications, containers, availability zones, and datacenters to help optimize your migrations.

See what matters—not just IP addresses

• View communication between services, pods, cloud regions, and cloud resources.
• Isolate network issues in your Envoy-powered service mesh and troubleshoot inefficient load balancing.
• Manage cloud networking costs by pinpointing the services and teams responsible for large traffic spikes.

Gain deep DNS visibility

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

Monitor connections to cloud services

• Pivot to integration metrics to determine if an issue lies with a cloud provider or originates from your systems.
• Filter down into subcomponents such as specific S3 buckets or RDS databases for more granular insights.
• Observe and analyze traffic to Amazon S3, Amazon Elastic Load Balancing (ELB),GCP BigQuery, and other managed cloud services.

View stats on any interface, on any device, on any network

• Take inventory with a complete list of all your network hardware.
• Monitor even the largest environments with a highly scalable and lightweight agent.
• Automatically discover and collect metrics on your network from any device, including those from Cisco, Palo Alto, Dell, F5, Juniper, and other leading brands.

Quickly expose performance with next-level tooling

• Search for devices and then drill down to view the performance of specific interfaces with a single click.
• Filter device data according to helpful parameters, such as location.
• Create custom dashboards with drag-and-drop widgets to help you evaluate device performance at a glance.

Get full visibility into traffic flows for troubleshooting and capacity planning

• Easily surface top talkers and rates of TCP flags such as RST, SYN, ACK, PSF, FIN, and URG.
• Filter network flow data by key information including volume, IP address, protocol, TCP/UDP source/destination port, and other out-of-the-box and custom tags.
• Collect network flow data in common formats and standards including Netflow, IPFIX, sFlow, and J-Flow.

Identify device-level problems with SNMP Traps

• Create monitors on specific SNMP Trap events to get alerted to device issues as soon as they occur.
• Speed up troubleshooting with access to full Trap context, including Trap name, OID, namespace, admin status, and more.
• Drill down into individual devices to see its SNMP Trap history.

Detect issues faster through advanced alerting

• Quickly configure alerts on many devices or interfaces at once.
• Use forecasting to determine when interfaces will exceed their available bandwidth.
• Rely on anomaly detection to quickly spot a malfunctioning device.

Reduce mean time to resolution (MTTR)

• Collaborate across teams, move faster, and solve problems more efficiently.
• Consolidate all your network monitoring needs into a single pane of glass.
• Correlate issues between network and application teams thanks to an all-in-one tool.

Troubleshoot network problems and create alerts using syslog messages

• Set syslog-based monitors on specific SNMP trap names or other elements of the syslog record.
• See syslog messages in the context of other events for improved troubleshooting.
• Retain device logs for root cause analysis and compliance.
