splunk kubernetes navigator

Square color values vary depending on which Colorby criteria you choose. Once you are in the drilldown view for ip-10-0-3-92.us-west-2.compute.internal, you can navigate to Splunk Log Observer to see all logs for the same host by clicking Logs for host ip-10-0-3-92.us-west-2.compute.internal on the related resources navigation menu. /* Dashboards and search for Kubernetes to find a dashboard. WebHello from Splunk Data Manager Team, We are excited to announce the preview of the new Kubernetes Navigator for Splunk Observability Cloud. Please select Then, the Analyzer produces theories about what those objects might have in common. WebKubernetes has the reputation of being hard to set up and operate. The Workload Detail panel displays detailed information about a selected workload. No, Please specify the reason For example, the redis-cart service is included in this Splunk Distribution of OpenTelemetry Collector configuration. Use the Group by drop-down menu in the control bar to partition instances by the selected dimension or property. WebSplunk is the key to enterprise resilience. This is relatively straightforward and lets you collect Kubernetes metrics without having to install an agent. You can also find various properties of the host, processes running on the host, and so on on the Properties sidebar. When you select a host or service from the sidebar, you are switching to the navigator for that host or service instance. The Nodes panel displays a compact list of all the nodes in your cluster, along with the infrastructure metrics, basic configuration, and health indicators such as CPU used, memory used, disk used, and so forth, for each node in your selected Kubernetes clusters. The following detail panels display metadata, infrastructure metrics, and events from the elements (node, workload, pod, or container) of your environment that are specified through the filters at the top of the page or that you selected from another page. Workload Detail: Display detailed information about a selected workload in a cluster. In most navigators, you have two options to monitor your instances: table view and heat map view. I found an error Review pod status in the Kubernetes navigator - Splunk Lantern If youre not already using Splunk Infrastructure Monitoring, get started with a 14-day trial. You can then investigate those specific instances to determine why they are behaving differently. 2005 - 2023 Splunk Inc. All rights reserved.

When you specify a Groupby field, you can select a group name to filter the navigator to only show the instances in that group. The color or statistics for an element, such as a pod, might change as you drill down or click through your system, because the information, such as, the state of the pod or its memory consumption statistics, might refresh between the time you start navigation and the time a target element appears. Recent trigger and clear events appear in the Workload Events chart. Enter your email address, and someone from the documentation team will respond to you: Please provide your comments here. Why am I not able to fetch Kubernetes logs? As you hover over or select the different options in the list, the instances immediately rearrange themselves in the navigator. WebThe following section applies to most navigators, except the Network Explorer and Kubernetes navigators. Splunk Kubernetes has emerged as the de-facto standard for orchestrating containerized microservices, but presents new monitoring requirements. The Analyzer panel helps you troubleshoot Kubernetes problems at scale by highlighting Kubernetes objects that are in a bad state such as nodes that are not ready. From any of the individual pods in this view, you can drill down to the Docker containers, navigate to the Kubernetes node hosting that pod, or view the node in other contexts. When the instances begin emitting values again, the squares are recolored accordingly. Splunk experts provide clear and actionable guidance. Here, well review how you can collect and visualize key Kubernetes metrics in Splunk Infrastructure Monitoring.

The status of the workloads helps you understand the health of the workloads. Description. names, product names, or trademarks belong to their respective owners. Each square has a color that represents the relative value of the metric you select from the Color by drop-down menu. 2005-2023 Splunk Inc. All rights reserved. Was this documentation topic helpful? You can still select the dimmed pods and containers to view details about them in the Info panel. View the health of a specific container ID you specify. View a summary of every container you are monitoring in Observability Cloud. to add our Splunk Helm chart repository and install the Smart Agent in your cluster. View the health of a specific pod you specify. The Map view lets you explore a cluster and visualize the health of everything at a glance. Splunk Infrastructure Monitoring integrates with every layer of your environment to provide end-to-end observability for Kubernetes environments: For basic monitoring of a Kubernetes cluster managed by a cloud provider, Splunk Infrastructure Monitoring can integrate directly with services like AWS CloudWatchand Google Stackdriverto collect data. As that information is streamed through Infrastructure Monitoring, the Kubernetes navigator dynamically produces interactive cluster maps, builds detailed node and workload lists, and populates built-in performance dashboards. Install the Splunk Add-on for Kubernetes Depending on your environment, your preferences, and the requirements of the add-on, you may need to install the add-on in multiple places. Monitor Kubernetes workloads across your infrastructure, or a specific subset of workloads, such as those running in a particular namespace. How do I know if appropriate resource limits have been applied, and if any pods are exceeding those limits? Zoom: Hover a cluster or node to display a magnifying glass icon in the upper left corner of the element. Please select If desired, you can specify a different cluster, node, or pod. For instance, you want to look into the details of a host named ip-10-0-3-92.us-west-2.compute.internal. Click around on containers in the pod to open the sidebar and drill down to details without losing context. Splunk, Splunk>, Turn Data Into Doing, Data-to-Everything, and D2E are trademarks or Transform your business in the cloud with Splunk. I found an error The level of detail shown on the map is dynamic and depends on the number of elements shown, either specified through the filters or whether you zoom in on to drill down for more detail. Use the Container Detail view when investigating an incident to get specific details. For details about using Tag Spotlight, see Analyze You can still select the dimmed pods and containers to view details about them in the sidebar. I found an error If you have only the public cloud service and the Smart Agent configured, some charts in the built-in dashboards for Amazon EC2, GCP Compute Engine, and Azure Virtual Machines instances display no data. Each Kubernetes service consists of the following elements: Container: A lightweight package containing everything needed to run applications. Navigators are sensitive to Splunk Connect for Kubernetes and Splunk Add-on for Kubernetes collect log and metrics data from your Kubernetes containers. The K8s workloads is focusing on providing information in regards to workloads a.k.a. However, you can clone a built-in dashboard to make changes to the clone, or download a built-in dashboard. This scenario describes how Kai, an SRE, and Deepu, a service owner, perform the following tasks using Splunk Observability Cloud to troubleshoot and identify the root cause of a recent Buttercup Games site incident: Receive alerts about outlier behavior For the following example navigator, the user selects 90 Critical alerts. Kai then opened Kubernetes Yes Before you can start monitoring any Kubernetes resources, Collect Kubernetes data, and log in with your administrator credentials. 2005 - 2023 Splunk Inc. All rights reserved. See why organizations around the world trust Splunk. You can explore data about each of those elements in the Info tab, allowing you to identify the underlying patterns noticeable on the filtered map that might be correlated with Kubernetes issues (for example, all failed pods only being in certain types of clusters) and provides suggested paths to follow for troubleshooting such issues.
