Question about sending Datadog metrics to Vector

[mpatterson2100-ctds]

I'm trying to use the datadog agent to send metrics to Vector, but something's not working.

Here's the vector config (toml)

[sources.dd_agent_metrics]
type = "datadog_agent"
address = "0.0.0.0:8282"

Here's the datadog config (yaml)

vector:
  metrics.enabled: true
  metrics.url: "http://localhost:8282" # Use https if SSL is enabled in Vector source configuration

This is running the same server inside of a datacenter.

I can see that vector is indeed listening on port 8282 using: telnet localhost 8282 and also using netstat. However, no metrics flow from datadog into vector and a tcpdump command tcpdump port 8282 -v yields no packets sent. Is there anything else I need to do in order to get Datadog to output metric data to vector?

Thanks in advance for any help!

Hello @mpatterson2100-ctds, my guess would be that your Datadog Agent is not sending data to your Vector instance. Your setup looks correct though per our guide here.

Based on https://docs.datadoghq.com/agent/troubleshooting/, you can do some additional checks to ensure (1) that the connection to Vector is established and (2) that metrics are being sent:

• datadog-agent status, to verify that the agent is up and running
• Enable debug https://docs.datadoghq.com/agent/troubleshooting/debug_mode/ and grep for errors related to Vector
