This process includes collecting performance data for troubleshooting insights, allowing for tracking and identifying issues promptly to ensure node performance and user satisfaction.<\/p>\n\n\n\n<p>While Kubernetes does offer built-in monitoring plugins, they may not provide the detailed visibility necessary for efficient <a href=\"https:\/\/middleware.io\/product\/container-monitoring\/\">container monitoring<\/a> and troubleshooting. <\/p>\n\n\n\n<p>Traditional monitoring tools also struggle to effectively monitor the various components enabled by Kubernetes. Consequently, numerous off-the-shelf monitoring solutions can provide timely and effective visibility into your Kubernetes clusters<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-why-is-kubernetes-monitoring-important\">Why is Kubernetes Monitoring Important?<\/h2>\n\n\n\n<p><strong>Kubernetes monitoring<\/strong> provides real-time performance insights, allowing for swift issue resolution and enhanced application uptime. It offers visibility into clusters and nodes, helping identify areas of improvement and operational issues.&nbsp;<\/p>\n\n\n\n<p>This timely response to issues is essential for seamless application upgrades, as it aids in node optimization, scaling decisions, and the detection of malfunctioning pods. Such monitoring improves planning and safeguards cluster stability.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-metrics-to-measure\">Metrics to Measure<\/h2>\n\n\n\n<p>Accurate coordination of metrics is crucial in <strong>Kubernetes monitoring best practices.<\/strong> Measuring the right metrics is essential for achieving end-to-end visibility of your Kubernetes clusters.<\/p>\n\n\n\n<p>Metrics play a pivotal role in setting up dashboard activities and alerts, offering insights into both the Kubernetes system and the applications running within it.<\/p>\n\n\n\n<p>You can obtain metrics from various sources, including cAdvisor, Metrics Server, Kubernetes API Server, and Kube-state-metrics, among others. Here are some key metrics to monitor in Kubernetes:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-cluster-monitoring\">Cluster Monitoring<\/h3>\n\n\n\n<p>The Kubernetes cluster serves as the primary host for all containers and the machines running applications. Therefore, monitoring its environment and the well-being of its components, such as nodes and pods, is crucial for successful container management.<\/p>\n\n\n\n<p>Key elements to monitor in a Kubernetes cluster include:<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-cluster-nodes\">Cluster Nodes<\/h4>\n\n\n\n<p>In a cluster are nodes that enable the running of applications. These nodes comprise several resources that allow them to carry out their function. You must observe these resources and monitor their health. Worker nodes host the containers while the master nodes manage the worker nodes&#8217; activities. &nbsp;<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-cluster-pods\">Cluster Pods<\/h4>\n\n\n\n<p>A pod is the smallest unit in a cluster and consists of one or more containers. The number of pods running determines the required number of nodes. Ensuring the health and resource usage of pods is critical for efficient <strong>Kubernetes monitoring<\/strong>.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-resource-utilization\">Resource Utilization<\/h4>\n\n\n\n<p>Understanding resource utilization metrics reveals the strengths and weaknesses of cluster nodes, helping determine adequacy and excess. Key resources to monitor include disk utilization, memory utilization, CPU utilization, network bandwidth, and more.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-pod-monitoring\">Pod Monitoring&nbsp;<\/h3>\n\n\n\n<p>Pods, which consist of containers deployed onto nodes, are fundamental to the Kubernetes ecosystem and require proper monitoring. Consider the following metrics for effective pod monitoring:<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Container Metrics<\/h4>\n\n\n\n<p>The number of containers running in a pod and their lifecycle must be understood and regulated. Avoid overloading pods and ensure scalability is optimized.<\/p>\n\n\n\n<div class=\"full-container-cta black\">\n    <div class=\"d-flex\">\n        <div class=\"img\">\n           <img decoding=\"async\" src=\"\/images\/k8s.png\" alt=\"K8s\">\n        <\/div>\n        <div class=\"content-cta\">\n            <h3>Monitor both Cluster and Pod level metrics in one application &#8211; Middleware.<\/h3>\n            <a href=\"https:\/\/app.middleware.io\/auth\/register\/\" target=\"_blank\" rel=\"noopener\"><button class=\"primary white arrow\">Get started<\/button><\/a>\n        <\/div>\n    <\/div>\n<\/div>\n\n\n\n<h4 class=\"wp-block-heading\">Application Metrics<\/h4>\n\n\n\n<p>Application metrics measure performance and provide industry-specific information. They offer insights into traffic, the rate of failed requests, request durations, feature usage, and other critical data.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Kubernetes Scaling and Availability Metrics<\/h4>\n\n\n\n<p>Understanding the scaling and availability capabilities of Kubernetes helps configure auto-scaling tools for clusters. The number of containers or pods in a cluster determines node requirements.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Load Average<\/h4>\n\n\n\n<p>Load average indicates the number of programs running or waiting to run on the CPU. Ensure it doesn&#8217;t exceed the number of CPU cores. Monitor load average in conjunction with sys CPU usage and I\/O wait for effective troubleshooting.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Resource Requests and Limits<\/h4>\n\n\n\n<p>Containers have associated resource requests and limits for CPU and memory. Properly manage these to avoid underutilization or overutilization. Aim for up to 80% actual usage on the 90th percentile for both resource requests and limits.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-monitoring-kubernetes-key-methods\">Monitoring Kubernetes: Key Methods<\/h2>\n\n\n\n<p>You can monitor your Kubernetes cluster nodes in two ways: using DaemonSets and Heapster. Both methods help collect metrics from the cluster and transmit them to an external endpoint for further analysis.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-monitoring-using-kubernetes-daemonsets\">Monitoring using Kubernetes DaemonSets&nbsp;<\/h3>\n\n\n\n<p>Kubernetes DaemonSets monitor individual pods and ensure that each one runs on every node in the cluster. They report the ability of a node to run the pods allocated to it. As a workload tool, object, or specialized pod, a DaemonSet acts as a monitoring agent that collects critical resource metrics from the containers and the node host, sending them to the API server.<\/p>\n\n\n\n<div class=\"container-cta small left\">\n<h3>Start monitoring your Kubernetes environment with granule details of each Node and Pod.<\/h3>\n    \t<a href=\"https:\/\/app.middleware.io\/auth\/register\/\" target=\"_blank\" rel=\"noopener\"><button class=\"primary white\">See it in action<\/button><\/a>\n<\/div>\n\n\n\n<p>Since a DaemonSet is a pod, you can create your specialized monitoring DaemonSet, which functions as a sister pod to your nodes. You can then configure Kubernetes to automatically attach this DaemonSet to each node you create.<\/p>\n\n\n\n<p>This allows the DaemonSet to monitor the node and its components. When a node is terminated, either manually (by you) or automatically (by Kubernetes self-healers), its designated monitoring DaemonSet is also terminated.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-kubernetes-monitoring-using-heapster\">Kubernetes Monitoring using Heapster<\/h3>\n\n\n\n<p>Heapster is a monitoring pod that collects and interprets signals and Kubernetes metrics. It serves as a link between the cluster and backend storage, which also serves as a log collector. Heapster enables performance analysis and visualization.<\/p>\n\n\n\n<p>Heapster queries the nodes about the containers running on them. It works with cAdvisor to expose container metrics such as CPU usage, network activity, and memory utilization.<\/p>\n\n\n\n<p>To efficiently monitor your containers using the Heapster method, you must use the pod in conjunction with a time-series database (TSDB) like InfluxDB and a visualization tool like Grafana. This requires deploying InfluxDB and Grafana and editing the Heapster deployment to send data to InfluxDB.<\/p>\n\n\n\n<p>These prerequisites make the Heapster monitoring method more complex than the DaemonSet method.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-monitoring-kubernetes-with-middleware\">Monitoring Kubernetes with Middleware<\/h2>\n\n\n\n<p>Middleware integrates every part of your Kubernetes cluster to provide a comprehensive view of its health and performance. After installing the <a href=\"https:\/\/docs.middleware.io\/quickstart\">Middleware agent<\/a>, it collects metrics, events, and logs from your cluster components, workload pods, and other Kubernetes objects.<\/p>\n\n\n\n<p>The Middleware agent integrates with container platforms like Docker to aggregate container-level metrics and provide a detailed breakdown of your container resources. This allows you to monitor relevant Kubernetes metrics at the pod and cluster levels.<\/p>\n\n\n\n<p>For node monitoring, the agent provides a graphical monitoring dashboard as illustrated below:<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"497\" src=\"https:\/\/middleware.io\/backend\/wp-content\/uploads\/2023\/01\/Nod-1024x497.png\" alt=\"Node monitoring with Middleware\" class=\"wp-image-4087\" srcset=\"https:\/\/stage-site.middleware.io\/wp-content\/uploads\/2023\/01\/Nod-1024x497.png 1024w, https:\/\/stage-site.middleware.io\/wp-content\/uploads\/2023\/01\/Nod-300x146.png 300w, https:\/\/stage-site.middleware.io\/wp-content\/uploads\/2023\/01\/Nod-768x373.png 768w, https:\/\/stage-site.middleware.io\/wp-content\/uploads\/2023\/01\/Nod-1536x746.png 1536w, https:\/\/stage-site.middleware.io\/wp-content\/uploads\/2023\/01\/Nod-1200x583.png 1200w, https:\/\/stage-site.middleware.io\/wp-content\/uploads\/2023\/01\/Nod.png 1920w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p>In the dashboard, the pods are displayed in sequential order with their names and UIDs, as shown in this image:<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"497\" src=\"https:\/\/middleware.io\/backend\/wp-content\/uploads\/2023\/01\/Pod1-1-1024x497.png\" alt=\"Pod monitoring - Middleware\" class=\"wp-image-4085\" srcset=\"https:\/\/stage-site.middleware.io\/wp-content\/uploads\/2023\/01\/Pod1-1-1024x497.png 1024w, https:\/\/stage-site.middleware.io\/wp-content\/uploads\/2023\/01\/Pod1-1-300x146.png 300w, https:\/\/stage-site.middleware.io\/wp-content\/uploads\/2023\/01\/Pod1-1-768x373.png 768w, https:\/\/stage-site.middleware.io\/wp-content\/uploads\/2023\/01\/Pod1-1-1536x746.png 1536w, https:\/\/stage-site.middleware.io\/wp-content\/uploads\/2023\/01\/Pod1-1-1200x583.png 1200w, https:\/\/stage-site.middleware.io\/wp-content\/uploads\/2023\/01\/Pod1-1.png 1920w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p>The Middleware agent is also equipped to provide granular visibility into the CPU usage of your pods, allowing you to view a typical CPU usage dashboard for pods.&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"497\" src=\"https:\/\/middleware.io\/backend\/wp-content\/uploads\/2023\/01\/Pod2-1024x497.png\" alt=\"K8s Pod CPU usage view in Middleware\" class=\"wp-image-4083\" srcset=\"https:\/\/stage-site.middleware.io\/wp-content\/uploads\/2023\/01\/Pod2-1024x497.png 1024w, https:\/\/stage-site.middleware.io\/wp-content\/uploads\/2023\/01\/Pod2-300x146.png 300w, https:\/\/stage-site.middleware.io\/wp-content\/uploads\/2023\/01\/Pod2-768x373.png 768w, https:\/\/stage-site.middleware.io\/wp-content\/uploads\/2023\/01\/Pod2-1536x746.png 1536w, https:\/\/stage-site.middleware.io\/wp-content\/uploads\/2023\/01\/Pod2-1200x583.png 1200w, https:\/\/stage-site.middleware.io\/wp-content\/uploads\/2023\/01\/Pod2.png 1920w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p>Middleware monitors and collects metrics for daemonsets, which facilitate the deployment of ongoing background tasks on specific nodes or all nodes as needed.
