Datadog

Datadog is a hosted infrastructure monitoring platform.

Introduction

This chart adds the DataDog Agent to all nodes in your cluster via a DaemonSet. It also depends on the kube-state-metrics chart.

Prerequisites

• Kubernetes 1.2+ with Beta APIs enabled

Installing the Chart

To install the chart with the release name my-release, retrieve your DataDog API key from your Agent Installation Instructions and run:

$ helm install --name my-release \
    --set datadog.apiKey=YOUR-KEY-HERE stable/datadog

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

Tip

: List all releases using helm list

Uninstalling the Chart

To uninstall/delete the my-release deployment:

$ helm delete my-release

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

Configuration

The following tables lists the configurable parameters of the Datadog chart and their default values.

Parameter	Description	Default
datadog.apiKey	Your Datadog API key	Nil You must provide your own key
image.repository	The image repository to pull from	datadog/docker-dd-agent
image.tag	The image tag to pull	latest
image.pullPolicy	Image pull policy	IfNotPresent
rbac.create	If true, create & use RBAC resources	true
rbac.serviceAccount	existing ServiceAccount to use (ignored if rbac.create=true)	default
datadog.env	Additional Datadog environment variables	nil
datadog.apmEnabled	Enable tracing from the host	nil
datadog.autoconf	Additional Datadog service discovery configurations	nil
datadog.checksd	Additional Datadog service checks	nil
datadog.confd	Additional Datadog service configurations	nil
datadog.volumes	Additional volumes for the daemonset or deployment	nil
datadog.volumeMounts	Additional volumeMounts for the daemonset or deployment	nil
resources.requests.cpu	CPU resource requests	100m
resources.limits.cpu	CPU resource limits	256m
resources.requests.memory	Memory resource requests	128Mi
resources.limits.memory	Memory resource limits	512Mi
kubeStateMetrics.enabled	If true, create kube-state-metrics	true
daemonset.podAnnotations	Annotations to add to the DaemonSet's Pods	nil
daemonset.tolerations	List of node taints to tolerate (requires Kubernetes >= 1.6)	nil
daemonset.useHostNetwork	If true, use the host's network	nil
daemonset.useHostPort	If true, use the same ports for both host and container	nil

Specify each parameter using the --set key=value[,key=value] argument to helm install. For example,

$ helm install --name my-release \
    --set datadog.apiKey=YOUR-KEY-HERE,datadog.logLevel=DEBUG \
    stable/datadog

Alternatively, a YAML file that specifies the values for the parameters can be provided while installing the chart. For example,

$ helm install --name my-release -f values.yaml stable/datadog

Tip

: You can use the default values.yaml

Image tags

Datadog offers a multitude of tags, including alpine based agents and JMX.

DaemonSet and Deployment

By default installs Datadog agent inside a DaemonSet. You may also use Datadog agent inside a Deployment, if you want to collect Kubernetes API events or send custom metrics to DogStatsD endpoint.

confd and checksd

The Datadog entrypoint will copy files found in /conf.d and /check.d to /etc/dd-agent/conf.d and /etc/dd-agent/check.d respectively. The keys for datadog.confd, datadog.autoconf, and datadog.checksd should mirror the content found in their respective ConfigMaps, ie

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