# Network Devices

The Network Devices dataset provides metadata and status information about all network devices discovered and monitored through Datadog's Network Device Monitoring (NDM). Each device is uniquely identified and enriched with details such as vendor, device type, location, IP address, and operational health. This dataset enables network and infrastructure teams to track device inventory, assess connectivity and reachability, and monitor the overall health of routers, switches, firewalls, and other critical devices across their environments.

| Device Status         | status        | core | string    | The high-level health status of the device as reported by Datadog.                                                                                                                            |
| Ping Reachability     | ping_status   | core | string    | Status of ICMP ping checks to the device. Indicates if the device is responding to network pings.                                                                                             |
| SNMP Profile          | profile       | core | string    | The Datadog NDM profile applied to the device, typically derived from its vendor and model (e.g., cisco-router, juniper-switch). Profiles determine which metrics and metadata are collected. |
| Vendor                | vendor        | core | string    | The manufacturer or provider of the device (e.g., Cisco, Juniper, Palo Alto Networks).                                                                                                        |
| Subnet                | subnet        | core | string    | The IP subnet (in CIDR notation) associated with the device. Useful for network segmentation and inventory grouping.                                                                          |
