The Datadog Agent can automatically track which services are running where, thanks to its Autodiscovery feature. Within minutes, you should see metrics with the prefix kubernetes_state. Kubectl create -f kube-state-metrics.yaml

And, if you’re running a large-scale production deployment, you can also install the Datadog Cluster Agent-in addition to the node-based Agent-as a centralized and streamlined way to collect cluster-data for deep visibility into your infrastructure. Our documentation details several other ways you can deploy the Datadog Agent, including using the Helm package manager and Datadog Operator. Now you can glance at your built-in Datadog dashboards for Kubernetes and Docker to see what those metrics look like.

Or, if you only want to install it on a specific subset of nodes, you can add a nodeSelector field to your pod configuration.ĪpiVersion : apps/v1 kind : DaemonSet metadata : name : datadog-agent namespace : default spec : selector : matchLabels : app : datadog-agent template : metadata : labels : app : datadog-agent name : datadog-agent spec : serviceAccountName : datadog containers : - image : datadog/agent:latest imagePullPolicy : Always name : datadog-agent ports : - containerPort : 8125 name : dogstatsdport protocol : UDP - containerPort : 8126 name : traceport protocol : TCP env : - name : DD_API_KEY value : - name : DD_COLLECT_KUBERNETES_EVENTS value : "true" - name : DD_LEADER_ELECTION value : "true" - name : KUBERNETES value : "true" - name : DD_HEALTH_PORT value : "5555" - name : DD_KUBELET_TLS_VERIFY value : "false" - name : DD_KUBERNETES_KUBELET_HOST valueFrom : fieldRef : fieldPath : status.hostIP - name : DD_APM_ENABLED value : "true" resources : requests : memory : "256Mi" cpu : "200m" limits : memory : "256Mi" cpu : "200m" volumeMounts : - name : dockersocket mountPath : /var/run/docker.sock - name : procdir mountPath : /host/proc readOnly : true - name : cgroups mountPath : /host/sys/fs/cgroup readOnly : true livenessProbe : httpGet : path : /health port : 5555 initialDelaySeconds : 15 periodSeconds : 15 timeoutSeconds : 5 successThreshold : 1 failureThreshold : 3 volumes : - hostPath : path : /var/run/docker.sock name : dockersocket - hostPath : path : /proc name : procdir - hostPath : path : /sys/fs/cgroup name : cgroups In this section, we will show you one way to install the containerized Datadog Agent as a DaemonSet on every node in your Kubernetes cluster.

Instrumenting applications to send custom metrics to Datadogįirst, you will need to deploy the Datadog Agent to collect key resource metrics and events from Kubernetes and Docker for monitoring in Datadog.

Collecting metrics with Autodiscovery: custom check configurations.

Collecting metrics with Autodiscovery: default check configurations.

Collecting Kubernetes and Docker metrics from your nodes.

Using this one example, we’ll step through several different layers of monitoring: We’ll use the guestbook-go example application from the Kubernetes project. In this guide, we’ll walk through setting up monitoring for a containerized application that is orchestrated by Kubernetes. Kubernetes is being widely adopted by forward-thinking organizations such as Box and GitHub for a number of reasons: its active community, rapid development, and of course its ability to schedule, automate, and manage distributed applications on dynamic container infrastructure. Since Kubernetes was open sourced by Google in 2014, it has steadily grown in popularity to become nearly synonymous with Docker orchestration. Within this blog post, we will refer to these terms as “primary” and “replica,” except for the sake of clarity in instances where we must reference a specific resource name. Editor’s note: Redis uses the terms “master” and “slave” to describe its architecture.
