Integration roundup: Monitoring your container-native technologies

Container-native technologies increase the scalability and speed of deployment offered by containerized infrastructure, but they also present new monitoring challenges for organizations that adopt them. For example, because containers are ephemeral and share resources, tracking resource provisioning in container-native tools is essential to ensure consistent application performance. Additionally, as adoption of containerized infrastructure continues to increase, so will the use of container-native tools; as a result, organizations that lack holistic monitoring approaches for these technologies may be left with a growing number of blind spots across their stack.

Datadog’s growing suite of container-native technology integrations enables users to monitor their entire containerized infrastructure from one place. This single pane of glass helps teams ensure that applications run seamlessly and that they can maintain an exceptional end-user experience. These integrations cover the full scope of container-native tools, including workflow automation solutions like Temporal, container networking tools like Cilium and Calico, and many more.

In this post, we’ll explore how several integrations we have recently released or updated help you monitor key areas of your container ecosystem, including:

• Service meshes with Istio and Envoy
• Autoscaling and resource utilization with Karpenter
• Continuous integration and continuous delivery (CI/CD) with Flux
• Messaging and streaming with Strimzi

However, our suite covers much more than these five tools. You can find a full list of our container-native integrations here.

Service meshes with Istio and Envoy

A service mesh is an infrastructure layer in microservice architectures that handles network traffic between services, independent of application code. Service meshes provide capabilities such as service discovery, load balancing, failure recovery, and authentication to help organizations address the challenges of managing services’ communication pathways, security, and observability at scale.

Istio is an open source service mesh that provides an efficient way to secure, connect, and monitor services without altering your application code. Istio’s control plane includes features such as TLS encryption; strong identity-based authentication and authorization; automatic load balancing for HTTP, gRPC, WebSocket, and TCP traffic; fine-grained control of traffic behavior with rich routing rules, retries, failovers, and fault injection; and automatic metrics, logs, and traces for all traffic within a cluster, including cluster ingress and egress.

The Istio dataplane is a set of Envoy proxies, which mediate and control all network communication between microservices. They also collect and report telemetry on all mesh traffic. In addition to Datadog’s standalone Istio integration, we have a designated integration to monitor Envoy as well. We recently updated this integration to collect additional telemetry, including metrics on role-based access control (RBAC) activity within your mesh, ensuring all of your service mesh telemetry is easily accessible in a single pane of glass.

With Datadog, you can monitor every aspect of your containerized service mesh environment:

• Use logs to assess the health of Envoy and the Istio control plane
• Break down the performance of your service mesh with request, bandwidth, and resource consumption metrics
• Map network communication between containers, pods, and services over the mesh with Network Performance Monitoring
• Drill down into distributed traces for applications transacting over the mesh with APM

We’ve also updated our out-of-the-box Envoy dashboard to provide a high-level view of your key service mesh metrics—such as incoming requests, listener traffic, CPU and memory usage, and more—so you can evaluate the health and performance of your service mesh environment at a glance.

Autoscaling and resource utilization with Karpenter

Flexibly allocating resources based on the demands of a growing customer base requires the ability to scale your infrastructure seamlessly. Container-native autoscaling and resource provisioning technologies help teams ensure that their containerized environments are consuming CPU and memory efficiently, so they can reduce waste and optimize allocation of computing resources.

Karpenter is a provisioning solution for Kubernetes that enables users to automate infrastructure scaling based on the changing resource requirements of their containerized workloads. Datadog’s Karpenter integration allows joint users to track resource consumption by pod, cluster, and component, helping them improve resource efficiency in their Kubernetes cluster.

The out-of-the-box dashboard provides a high-level overview of the health of your cluster, including nodes, pods, and resource requests, enabling you to fine-tune your resource allocation according to the particular needs of your application. For instance, if you notice a spike in CPU requests across your pods, you can pivot to Karpenter to quickly provision the node hosting these pods with additional CPU resources and avoid any performance issues that might arise from underprovisioning.

The dashboard also provides a spatial representation of pod evolution, grouped by lifecycle phase, zone, capacity type, and more, helping users understand their cluster architecture. Furthermore, users can analyze the frequency and latency of their Karpenter provisioner’s actions and alert on a high number of pods stuck in unsuccessful states. With this data, users can make informed decisions on how to optimize their provisioning constraints.

CI/CD with Flux

CI/CD tools enable teams to automate the building, testing, and deployment of containerized applications by ensuring that code changes are reliable and seamless. CI/CD pipelines can help establish a rapid development and release cycle, which allows teams to stay agile, adjust to a rapidly changing marketplace, and deliver consistent value to end users.

Flux is a set of CI/CD solutions for Kubernetes, including feature flags, A/B rollouts, and automated container image updates. Flux utilizes a GitOps toolkit to help ensure that your system is version-controlled and matches the desired state in your Git repository. Datadog’s Flux integration surfaces performance metrics related to the health of these Kubernetes-specific delivery solutions.

With this integration, joint Datadog and Flux customers can monitor the health of their CI/CD systems. For instance, a DevOps engineer can easily surface metrics like the number of currently used workers per controller, process duration, and status of a GitOps Toolkit resource. They can use this data to troubleshoot a failing CI/CD pipeline by, for instance, restarting a GitOps Toolkit resource that was suspended and thus enabling the code deployment to be pushed to production.

Datadog also integrates with Argo CD—a CD tool for Kubernetes that ensures that your Kubernetes clusters are up to date with your latest manifest files. This integration enables users to monitor how quickly and accurately Argo CD is applying changes to their clusters along with the statuses and performance of their continuous delivery pipelines, ensuring swifter, safer deployments, and thus an application that can adapt to the rapidly evolving needs of end users.

Messaging and streaming with Strimzi

Messaging platforms facilitate communication between microservices and support event-driven architectures by enabling the asynchronous exchange of data.

Strimzi is an open source project that simplifies the process of configuring, customizing, and running Kafka on Kubernetes by managing Kafka clusters as custom resources. Datadog’s Strimzi integration collects metrics on operations and health sliced by Cluster, Topic, and User operators.

Users can manage uneven system load distribution by tracking activity and resource consumption at the Topic level. These insights are useful in improving streaming efficiency from producer through to consumer. Furthermore, users can monitor reconciliations by successful, failed, and locked status to troubleshoot operator access issues, minimize misconfiguration risks, and detect unauthorized access. Finally, users can also visualize resource, reconciliation, and thread count by operator level within our out-of-the-box dashboard. These visualizations help you quickly understand ongoing activity at each stage of the data streaming pipeline within your Strimzi framework.
