Overview

Use Observability Pipelines’ Datadog Metrics destination (PreviewPREVIEW indicates an early access version of a major product or feature that you can opt into before its official release.Glossary) to send metrics to Datadog. You can also use AWS PrivateLink to send metrics from Observability Pipelines to Datadog.

Setup

Set up the Datadog Metrics destination and its environment variables when you set up a pipeline. The information below is configured in the pipelines UI.

Set up the destination

Optional settings

Toggle the switch to enable Buffering Options. Enable a configurable buffer on your destination to ensure intermittent latency or an outage at the destination doesn’t create immediate backpressure, and allow events to continue to be ingested from your source. Disk buffers can also increase pipeline durability by writing data to disk, ensuring buffered data persists through a Worker restart. See Destination buffers for more information.

• If left unconfigured, your destination uses a memory buffer with a capacity of 500 events.
• To configure a buffer on your destination:
  1. Select the buffer type you want to set (Memory or Disk).
  2. Enter the buffer size and select the unit.
     1. Maximum memory buffer size is 128 GB.
     2. Maximum disk buffer size is 500 GB.
  3. In the Behavior on full buffer dropdown menu, select whether you want to block events or drop new events when the buffer is full.

Set secrets

These are the defaults used for secret identifiers and environment variables.

Note: If you enter secret identifiers and then choose to use environment variables, the environment variable is the identifier entered and prepended with DD_OP. For example, if you entered PASSWORD_1 for a password identifier, the environment variable for that password is DD_OP_PASSWORD_1.

How the destination works

A batch of events is flushed when one of these parameters is met. See event batching for more information.

AWS PrivateLink

To send metrics from Observability Pipelines to Datadog using AWS PrivateLink, see Connect to Datadog over AWS PrivateLink for setup instructions. The two endpoints you need to set up are:

• Metrics:
• Remote Configuration:

Note: The obpipeline-intake.datadoghq.com endpoint is used for Live Capture and is not available as a PrivateLink endpoint.
