Kubernetes entity details
A Kubernetes cluster entity is created for each cluster that is monitored. High level summaries of the Kubernetes clusters are available in widgets in the Kubernetes area overview nested under the Infrastructure Overview.
Each Kubernetes cluster has its own details page with information about its health, workloads, events, network topology, and integrations with other SolarWinds Observability SaaS features. The Kubernetes cluster details also display the tag of the Docker image used by a container that shares the same name as its corresponding Kubernetes deployment, providing you with the option to quickly identify the specific version of the deployed application.
You can also extend your entity details with Kubernetes annotations with a special swo.cloud.solarwinds.com/ prefix.
In addition to general performance metrics for the cluster itself, each Kubernetes cluster entity monitors the following items as individual entities: Nodes, Namespaces, Pods, Deployments, StatefulSets, DaemonSets, Jobs, Services, Persistent volumes, and Persistent volume claims. To view details about each monitored element, open the cluster details page, click the tab for the respective element type, and click an element in the list. Kubernetes clusters, Nodes, and Deployments are also available in the Entity Explorer.
All collected metrics and logs are also available in the Metrics Explorer and Logs Explorer.
Kubernetes Events
The Events tab of the Kubernetes cluster details view of the Entity Explorer lists events collected from your cluster during the specified time period. The tab is available also on the Node details pages, showing only events related to those nodes. To create alerts for Kubernetes events, hover over the event you want to create an alert for, click the vertical ellipsis (
) on the right, and select Create alert. To find a specific event, do any of the following:
-
To change the time period, click the drop-down menu in the upper-right corner and choose how much historical data to display. You can choose to view all recent data for standard lengths of time, or to view data between two dates.
To show data from a custom time period, choose Custom. In the calendar that appears, click the starting date of your time period and click the ending date. The time period's start and end times default to the current time. To change a start or end time, click the clock next to the time you want to change and click the desired time.
-
Enter text in the search field to find an event based on the message text.
- Click
to open the Filters pane, and select one or more filters to specify what events to include.
Kubernetes widgets
In addition to standard visualizations of metric data, the following widgets display detailed insights into your Kubernetes containers, clusters, and nodes.
Active Alerts
An overview of the active alerts triggered by clusters, categorized by severity. Active alerts are alerts that have been triggered but not cleared. This includes acknowledged alerts.
Inventory
The Inventory widget summarizes the status of key Kubernetes entities across all your clusters, including Nodes, Pods, Deployments, StatefulSets, DaemonSets, APM Services, and Databases. For each entity, it displays either a health score (for Clusters) or a status breakdown (for Pods, Deployments, StatefulSets, etc.)
Utilization
The Utilization widget displays average CPU usage across all clusters over specified time range. You can switch the metric (e.g., Memory, Storage) using the dropdown menu. The chart is color-coded per cluster.
Last 10
The Last 10 Changes widget lists the most recent Kubernetes manifest changes across all the clusters. Clicking on a row opens a modal window that compares the previous version of the entity manifest with the latest. To filter changes by type (e.g., Created, Updated, Removed), use the dropdown menu in the top right corner of the widget.
