Use NetFlow Monitoring in Datadog to visualize and monitor your flow records from your Netflow-enabled devices.
To use NetFlow Monitoring with Network Device Monitoring, ensure you are using the Agent version 7.39 or newer.
Note: Configuring metric collection from Network Device Monitoring is not a requirement for sending NetFlow data, although it is strongly recommended.
To configure your devices to send NetFlow, sFlow, or IPFIX traffic to the Agent NetFlow server, your devices must be configured to send traffic to the IP address that the Datadog Agent is installed on, specifically the flow_type
and port
.
Edit your datadog.yaml
Agent configuration file to enable NetFlow:
network_devices:
netflow:
enabled: true
listeners:
- flow_type: netflow9 # choices: netflow5, netflow9, ipfix, sflow5
port: 2055 # devices must send traffic to this port
- flow_type: netflow5
port: 2056
- flow_type: ipfix
port: 4739
- flow_type: sflow5
port: 6343
After saving your changes, restart the Agent.
