Network Device Monitoring helps you gain insights into the health and performance of your on-prem routers, switches, and firewalls. Once the Datadog Agent is installed on a host that has access to the network, the Agent can autodiscover network devices and collect metrics right out of the box.
This guide covers configuring Network Device Monitoring on your hosts, enriching device tags, setting up and viewing device profiles, viewing data in NetFlow Monitoring, and validating data in the provided dashboards and Device Topology Map.
The following diagram illustrates the data flow between Syslog, SNMP traps, and NetFlow information. The devices send the relevant information to the Datadog Agent over the ports as shown in the diagram (ports can be changed if needed by configuration in the Agent). For API based integrations, the Datadog Agent connects with the network device vendor software controllers or managers on-premise or in the cloud based on specific https API integrations instructions per vendor. The Datadog Agent, configured with NDM and deployed on-premises or in the cloud, consolidates all collected device and network data from your network and sends it to Datadog over HTTPS on port 443. This provides unified, full-stack observability of metrics, logs, traces, monitors, and dashboards.
Datadog Agent High Availability in Network Device Monitoring is not supported for your selected Datadog site (US1).
Datadog Agent High Availability in Network Device Monitoring is in Preview. Reach out to your Datadog representative to sign up.
High Availability (HA) in Network Device Monitoring allows you to designate an active Agent and a standby Agent, ensuring automatic failover if the active Agent encounters an issue. This setup eliminates the Agent as a single point of failure, maintaining continuous monitoring during unexpected incidents or planned maintenance, such as OS updates and Agent upgrades.
You can configure active and standby Agents to function as an HA pair in NDM. If the active Agent goes down, the standby Agent takes over within 90 seconds, becoming the new active Agent. Additionally, you can designate a preferred active Agent, allowing NDM to automatically revert to it once it becomes available again. This feature allows for proactive Agent switching ahead of scheduled maintenance.
Dynamically enrich network devices monitored by Datadog Network Device Monitoring with data defined in ServiceNow’s CMDB (Configuration Management Database).
Customize metrics and tags on your devices by viewing the Supported Devices page to view out-of-the-box device profiles. If you would like to edit or add more metrics, the following options are available:
