Overview

Network Device Monitoring gives you visibility into your on-premise and virtual network devices, such as routers, switches, and firewalls. Automatically discover devices on any network, and quickly start collecting metrics like bandwidth utilization, volume of bytes sent, and determine whether devices are up/down.

Getting started

1. Install the Datadog Agent (usually on a server that is not the monitored device).
2. Configure the SNMP integration by either monitoring individual devices, or using device autodiscovery.
3. Start monitoring your entire network infrastructure on the Network Devices page.
4. View metrics collected on Datadog’s out-of-the-box dashboards:
   • Overview of all devices monitored
   • Across the performance on all interfaces
5. Catch issues before they arise with proactive monitoring on any SNMP metric.

Supported devices

Generic profile

The generic profile collects metrics for all devices not supported by a vendor profile. Metrics include TCP, UDP, IP, and interface metrics such as bandwidth utilization, volume sent/received, etc.

SD-WAN

Datadog provides SD-WAN (Software-Defined Wide Area Network) monitoring for select vendors. SD-WAN is a type of networking technology that uses software-defined networking (SDN) principles to manage and optimize the performance of wide area networks (WANs). It is mainly used to interconnect remote offices and data centers across different transports (MPLS, Broadband, 5G, and so on). SD-WAN benefits from automatic load balancing and failure detection across these transports.

Datadog supports the following vendors for SD-WAN network monitoring:

• Meraki SD-WAN (public beta)
• Cisco SD-WAN (private beta)

Vendor profiles

The following vendor devices are supported with dedicated profiles. If a vendor or device type is supported, but the specific model isn’t supported, you can:

• customize your own YAML profile (see the NDM troubleshooting FAQ page for guidance)
• create new profiles to start monitoring new device models
