Datadog Overview

So, you’ve just finished installing the Datadog Agent, or maybe you’re just curious about what (else) Datadog can do for you. This document gives a high level overview of Datadog’s capabilities and how it can help you bring your infrastructure to heel.


  • About 100 integrations officially listed, always adding more.
  • Custom integrations are available via our API, many documented by our active user community.
  • The Agent is open source and you can instrument your own if you’d like.
  • Once integrations have been configured, data living in a datacenter or in an online service is treated the same throughout Datadog.


  • All machines show up in the infrastructure overview
  • Here you can see the tags applied to each machine; as they’re assigned to perform certain roles, tagging allows you to indicate machines have a certain purpose
  • We do as much as possible to automatically categorize your servers for you, to create structure in your infrastructure with as little work as possible (unlike explicitly creating all your clusters). Thus if a new machine is tagged, you can immediately see the stats for that machine based on what was previously set up for that tag.
  • For more on tagging, please see here.

Host Map

The Host Map can be found under the Infrastructure menu and offers the ability to:

  • Quickly visualize your entire environment regardless of whether it’s 5, 500, or 50,000 hosts.
  • Identify outliers
  • Detect usage patterns
  • Optimize resources

To learn more about the Host Map, visit the Host Map Guide.


The Event Stream is based on the same conventions as a blog:

  • Every event in the stream can be commented on.
  • Great for distributed teams and maintaining the focus of an investigation
  • You can filter by: user, source, tag, host, status, priority, incident

For each incident users can:

  • Claim it
  • Increase/decrease priority
  • Comment
  • See similar incidents
  • @ notify team members, who receive an email
  • @support-datadog to ask for assistance


Dashboards contain graphs with real-time performance metrics

  • Synchronous mousing across all graphs in a dashboard.
  • Vertical bars are events in the context of the metric.
  • Click & drag on a graph to zoom-in on a particular time-frame.
  • As you hover over the graph the event stream moves with you.
  • Display by zone, host, or total usage.
  • We expose the JSON editor of the graph allowing for arithmetic and functions to be applied to metrics.
  • Share a graph snapshot that will appear in the stream; clicking on that snapshot returns you to the original dashboard (via the camera in the upper right of a graph).
  • Graphs can be embedded in an iframe, giving a 3rd party a live graph without access to your data or any other information (via the pencil in the upper right of a graph).


Monitoring gives you the ability to be notified if the aggregate of a specific metric is above or below a certain threshold:

  • Across your entire infrastructure
  • Per machine (average, max, min, or sum)
  • Applies to any metric you want, revenue: data center temperature, etc.
  • Multi alerts (by device, host, etc.)
  • Set alert notification message, including @ capabilities

Does the data have to be pushed to Datadog?

Currently, yes:

  1. All integrations we have get data flowing almost automatically after launching the Agent (intial reporting may take a few minutes, but not longer than 10).
  2. If you have custom metrics, you can indicate specifically where to pull the data from.
