Overview

Cribl Stream helps you process machine data logs, instrumentation data, application data, and metrics in real time, and deliver it to your analysis platform of choice. It allows you to:

  • Add context to your data, by enriching it with information from external data sources.
  • Help secure your data, by redacting, obfuscating, or encrypting sensitive fields.
  • Optimize your data, per your performance and cost requirements.

This is for the self-hosted Cribl Stream version.

Use the out-of-the-box dashboard to view the performance of the Stream with base metrics like events per second, bytes per second, input types, output types, and infrastructure metrics. Monitor reduction percentages by events or bytes, which is useful for improving search performance or licensing and infrastructure costs for the systems of analysis.

Setup

You can send your Cribl Stream internal metrics to the Datadog API.

Installation

Datadog

Navigate to API Keys under Organization Settings and create an API Key for Cribl to send data.

Cribl

  1. In Cribl, navigate to Quick Connects and click the +Add Source button. step1
  2. Scroll down to System Internal , hover over Cribl Internal and choose Select Existing. Enable both CriblLogs and CriblMetrics.
  • Note: Both sources must have Quick Connect enabled instead of Routes. step3

  1. Click the +Add Destination button.

  2. Scroll to the Datadog tile and click +Add New.

  3. Give a name to the input (for example, Cribl_Datadog). step4

  4. Next, enter your Datadog API Key and select your Datadog site.

  5. Add any Datadog tags, a Message Field, Source, or Host information. For more information, see the Cribl Datadog Destination documentation.

  6. Click Save.

  7. Select Passthru to connect Cribl Metrics to your Datadog destination. step5

Uninstallation

Use the delete dashboard option within the Cribl Stream dashboard settings to delete the Cribl Stream dashboard. Remove the Datadog destination from the Cribl Stream deployment to stop sending data.
