Datadog

Version: 2.37.4 AppVersion: 7

Datadog is a hosted infrastructure monitoring platform. This chart adds the Datadog Agent to all nodes in your cluster via a DaemonSet. It also optionally depends on the kube-state-metrics chart. For more information about monitoring Kubernetes with Datadog, please refer to the Datadog documentation website.

Datadog offers two variants, switch to a -jmx tag if you need to run JMX/java integrations. The chart also supports running the standalone dogstatsd image.

See the Datadog JMX integration to learn more.

How to use Datadog Helm repository

You need to add this repository to your Helm repositories:

helm repo add datadog https://helm.datadoghq.com
helm repo update

Prerequisites

Kubernetes 1.10+ or OpenShift 3.10+, note that:

Requirements

Repository Name Version
https://helm.datadoghq.com datadog-crds 0.4.7
https://prometheus-community.github.io/helm-charts kube-state-metrics 2.13.2

Quick start

By default, the Datadog Agent runs in a DaemonSet. It can alternatively run inside a Deployment for special use cases.

Note: simultaneous DaemonSet + Deployment installation within a single release will be deprecated in a future version, requiring two releases to achieve this.

Installing the Datadog Chart

To install the chart with the release name <RELEASE_NAME>, retrieve your Datadog API key from your Agent Installation Instructions and run:

For Helm 3:

helm install <RELEASE_NAME> \
    --set datadog.apiKey=<DATADOG_API_KEY> datadog/datadog

For Helm 2:

helm install --name <RELEASE_NAME> \
    --set datadog.apiKey=<DATADOG_API_KEY> datadog/datadog

By default, this Chart creates a Secret and puts an API key in that Secret. However, you can use manually created secrets by setting the datadog.apiKeyExistingSecret and/or datadog.appKeyExistingSecret values (see Creating a Secret, below).

Note: When creating the secret(s), be sure to name the key fields api-key and app-key.

After a few minutes, you should see hosts and metrics being reported in Datadog.

Note: You can set your Datadog site using the datadog.site field.

For Helm 3:

helm install <RELEASE_NAME> \
    --set datadog.appKey=<DATADOG_APP_KEY> \
    --set datadog.site=<DATADOG_SITE> \
    datadog/datadog

For Helm 2:

helm install --name <RELEASE_NAME> \
    --set datadog.appKey=<DATADOG_APP_KEY> \
    --set datadog.site=<DATADOG_SITE> \
    datadog/datadog

Create and provide a secret that contains your Datadog API and APP Keys

To create a secret that contains your Datadog API key, replace the <DATADOG_API_KEY> below with the API key for your organization. This secret is used in the manifest to deploy the Datadog Agent.

DATADOG_API_SECRET_NAME=datadog-api-secret
kubectl create secret generic $DATADOG_API_SECRET_NAME --from-literal api-key="<DATADOG_API_KEY>"

Note: This creates a secret in the default namespace. If you are in a custom namespace, update the namespace parameter of the command before running it.

Now, the installation command contains the reference to the secret.

For Helm 3:

helm install <RELEASE_NAME> \
  --set datadog.apiKeyExistingSecret=$DATADOG_API_SECRET_NAME datadog/datadog

For Helm 2:

helm install --name <RELEASE_NAME> \
  --set datadog.apiKeyExistingSecret=$DATADOG_API_SECRET_NAME datadog/datadog

Enabling the Datadog Cluster Agent

The Datadog Cluster Agent is now enabled by default.

Read about the Datadog Cluster Agent in the official documentation.

Custom Metrics Server

If you plan to use the Custom Metrics Server feature, provide a secret for the application key (AppKey) using the datadog.appKeyExistingSecret chart variable.

DATADOG_APP_SECRET_NAME=datadog-app-secret
kubectl create secret generic $DATADOG_APP_SECRET_NAME --from-literal app-key="<DATADOG_APP_KEY>"

Note: the same secret can store the API and APP keys

DATADOG_SECRET_NAME=datadog-secret
kubectl create secret generic $DATADOG_SECRET_NAME --from-literal api-key="<DATADOG_API_KEY>" --from-literal app-key="<DATADOG_APP_KEY>"

Run the following if you want to deploy the chart with the Custom Metrics Server enabled in the Cluster Agent:

For Helm 3:

helm install datadog-monitoring \
    --set datadog.apiKeyExistingSecret=$DATADOG_API_SECRET_NAME  \
    --set datadog.appKeyExistingSecret=$DATADOG_APP_SECRET_NAME \
    --set clusterAgent.enabled=true \
    --set clusterAgent.metricsProvider.enabled=true \
    datadog/datadog

For Helm 2:

helm install --name datadog-monitoring \
    --set datadog.apiKeyExistingSecret=$DATADOG_API_SECRET_NAME  \
    --set datadog.appKeyExistingSecret=$DATADOG_APP_SECRET_NAME \
    --set clusterAgent.enabled=true \
    --set clusterAgent.metricsProvider.enabled=true \
    datadog/datadog

If you want to learn to use this feature, you can check out this Datadog Cluster Agent walkthrough.

The Leader Election is enabled by default in the chart for the Cluster Agent. Only the Cluster Agent(s) participate in the election, in case you have several replicas configured (using clusterAgent.replicas.

Cluster Agent Token

You can specify the Datadog Cluster Agent token used to secure the communication between the Cluster Agent(s) and the Agents with clusterAgent.token.

Upgrading

From 1.x to 2.x

⚠️ Migrating from 1.x to 2.x requires a manual action.

The datadog chart has been refactored to regroup the values.yaml parameters in a more logical way. Please follow the migration guide to update your values.yaml file.

From 1.19.0 onwards

Version 1.19.0 introduces the use of release name as full name if it contains the chart name(datadog in this case). E.g. with a release name of datadog, this renames the DaemonSet from datadog-datadog to datadog. The suggested approach is to delete the release and reinstall it.

From 1.0.0 onwards

Starting with version 1.0.0, this chart does not support deploying Agent 5.x anymore. If you cannot upgrade to Agent 6.x or later, you can use a previous version of the chart by calling helm install with --version 0.18.0.

See 0.18.1's README to see which options were supported at the time.

Uninstalling the Chart

To uninstall/delete the <RELEASE_NAME> deployment:

helm delete <RELEASE_NAME> --purge

The command removes all the Kubernetes components associated with the chart and deletes the release.

Configuration

As a best practice, a YAML file that specifies the values for the chart parameters should be used to configure the chart. Any parameters not specified in this file will default to those set in values.yaml.

  1. Create an empty datadog-values.yaml file.
  2. Create a Kubernetes secret to store your Datadog API key and App key
kubectl create secret generic datadog-secret --from-literal api-key=$DD_API_KEY --from-literal app-key=$DD_APP_KEY
  1. Set the following parameters in your datadog-values.yaml file to reference the secret:
datadog:
  apiKeyExistingSecret: datadog-secret
  appKeyExistingSecret: datadog-secret
  1. Install or upgrade the Datadog Helm chart with the new datadog-values.yaml file:

For Helm 3:

helm install -f datadog-values.yaml <RELEASE_NAME> datadog/datadog

For Helm 2:

helm install -f datadog-values.yaml --name <RELEASE_NAME> datadog/datadog

OR

For Helm 3:

helm upgrade -f datadog-values.yaml <RELEASE_NAME> datadog/datadog

For Helm 2:

helm upgrade -f datadog-values.yaml --name <RELEASE_NAME> datadog/datadog

See the All configuration options section to discover all configuration possibilities in the Datadog chart.

Configuring Dogstatsd in the agent

The agent will start a server running Dogstatsd in order to process custom metrics sent from your applications. Check out the official documentation on Dogstatsd for more details.

By default the agent will create a unix domain socket to process the datagrams (not supported on Windows, see below).

To disable the socket in favor of the hostPort, use the following configuration:

datadog:
  #(...)
  dogstatsd:
    useSocketVolume: false
    useHostPort: true

Enabling APM and Tracing

APM is enabled by default using a socket for communication in the out-of-the-box values.yaml file; more details about application configuration are available on the official documentation. Update your datadog-values.yaml file with the following configration to enable TCP communication using a hostPort:

datadog:
  # (...)
  apm:
    portEnabled: true

To disable APM, set socketEnabled to false in your datadog-values.yaml file (portEnabled is false by default):

datadog:
  # (...)
  apm:
    socketEnabled: false

Enabling Log Collection

Update your datadog-values.yaml file with the following log collection configuration:

datadog:
  # (...)
  logs:
    enabled: true
    containerCollectAll: true

then upgrade your Datadog Helm chart:

For Helm 3:

helm upgrade -f datadog-values.yaml <RELEASE_NAME> datadog/datadog

For Helm 2:

helm upgrade -f datadog-values.yaml --name <RELEASE_NAME> datadog/datadog

Enabling Process Collection

Update your datadog-values.yaml file with the process collection configuration:

datadog:
  # (...)
  processAgent:
    enabled: true
    processCollection: true

then upgrade your Datadog Helm chart:

helm upgrade -f datadog-values.yaml <RELEASE_NAME> datadog/datadog

Enabling NPM Collection

The system-probe agent only runs in dedicated container environment. Update your datadog-values.yaml file with the NPM collection configuration:

datadog:
  # (...)
  networkMonitoring:
    # (...)
    enabled: true

# (...)

then upgrade your Datadog Helm chart:

helm upgrade -f datadog-values.yaml <RELEASE_NAME> datadog/datadog

Kubernetes event collection

Use the Datadog Cluster Agent to collect Kubernetes events. Please read the official documentation for more context.

Alternatively set the datadog.leaderElection, datadog.collectEvents and rbac.create options to true in order to enable Kubernetes event collection.

conf.d and checks.d

The Datadog entrypoint copies files with a .yaml extension found in /conf.d and files with .py extension in /checks.d to /etc/datadog-agent/conf.d and /etc/datadog-agent/checks.d respectively.

The keys for datadog.confd and datadog.checksd should mirror the content found in their respective ConfigMaps. Update your datadog-values.yaml file with the check configurations:

datadog:
  confd:
    redisdb.yaml: |-
      ad_identifiers:
        - redis
        - bitnami/redis
      init_config:
      instances:
        - host: "%%host%%"
          port: "%%port%%"
    jmx.yaml: |-
      ad_identifiers:
        - openjdk
      instance_config:
      instances:
        - host: "%%host%%"
          port: "%%port_0%%"
    redisdb.yaml: |-
      init_config:
      instances:
        - host: "outside-k8s.example.com"
          port: 6379

then upgrade your Datadog Helm chart:

helm upgrade -f datadog-values.yaml <RELEASE_NAME> datadog/datadog

For more details, please refer to the documentation.

Kubernetes Labels and Annotations

To map Kubernetes node labels and pod labels and annotations to Datadog tags, provide a dictionary with kubernetes labels/annotations as keys and Datadog tags key as values in your datadog-values.yaml file:

nodeLabelsAsTags:
  beta.kubernetes.io/instance-type: aws_instance_type
  kubernetes.io/role: kube_role
podAnnotationsAsTags:
  iam.amazonaws.com/role: kube_iamrole
podLabelsAsTags:
  app: kube_app
  release: helm_release

then upgrade your Datadog Helm chart:

helm upgrade -f datadog-values.yaml <RELEASE_NAME> datadog/datadog

CRI integration

As of the version 6.6.0, the Datadog Agent supports collecting metrics from any container runtime interface used in your cluster. Configure the location path of the socket with datadog.criSocketPath; default is the Docker container runtime socket. To deactivate this support, you just need to unset the datadog.criSocketPath setting. Standard paths are:

  • Docker socket: /var/run/docker.sock
  • Containerd socket: /var/run/containerd/containerd.sock
  • Cri-o socket: /var/run/crio/crio.sock

Configuration required for Amazon Linux 2 based nodes

Amazon Linux 2 does not support apparmor profile enforcement. Amazon Linux 2 is the default operating system for AWS Elastic Kubernetes Service (EKS) based clusters. Update your datadog-values.yaml file to disable apparmor enforcement:

agents:
  # (...)
  podSecurity:
    # (...)
    apparmor:
      # (...)
      enabled: false

# (...)

All configuration options

The following table lists the configurable parameters of the Datadog chart and their default values. Specify each parameter using the --set key=value[,key=value] argument to helm install. For example,

For Helm 3:

helm install <RELEASE_NAME> \
  --set datadog.apiKey=<DATADOG_API_KEY>,datadog.logLevel=DEBUG \
  datadog/datadog

For Helm 2:

helm install --name <RELEASE_NAME> \
  --set datadog.apiKey=<DATADOG_API_KEY>,datadog.logLevel=DEBUG \

How to join a Cluster Agent from another helm chart deployment (Linux)

Because the Cluster Agent can only be deployed on Linux Node, the communication between the Agents deployed on the Windows nodes with the a Cluster Agent need to be configured.

The following datadog-values.yaml file contains all the parameters needed to configure this communication.

targetSystem: windows

existingClusterAgent:
  join: true
  serviceName: "<EXISTING_DCA_SERVICE_NAME>" # from the other datadog helm chart release
  tokenSecretName: "<EXISTING_DCA_SECRET_NAME>" # from the other datadog helm chart release

# Disabled datadogMetrics deployment since it should have been already deployed with the other chart release.
datadog-crds:
  crds:
    datadogMetrics: false

# Disable kube-state-metrics deployment
datadog:
  kubeStateMetricsEnabled: false
