Containers Insight 2.0: Dashboard and Widget Guide
Overview
Containers Insight 2.0 provides a default dashboard to display a summary of cost and efficiency for all clusters. It also supports powerful customization of the dashboard. Custom widgets can be used to query rich datasets to reveal deeper insights into cost, utilization, and efficiency within Kubernetes, and OpenShift Clusters.
A dashboard appears by default. You can also create custom dashboards.
Default Dashboard
The default dashboard includes KPI widgets such as Total Cost, Idle Cost, and Efficiency Score. It also displays time series chart widgets, showing trends for the top 10 idle cost clusters, and total cost trends for the top 10 clusters. Any changes to the dashboard, such as adding or deleting widgets, updating the layout, or adjusting global filters, are automatically saved. Each user has his/ her own default dashboard that can be customized independently.
Custom Dashboard
Users can create custom dashboards by saving any existing dashboards available to them. The layout of the dashboard is structured with KPI widgets on the top, chart widgets in the middle, and a table widget at the bottom. Within each section (KPI, chart), the placement of the widgets can be adjusted. If a user deletes all dashboards, they will still receive the pre-configured built-in default dashboard. Any changes, including global filters and layout adjustments, are automatically saved.
There are several widgets that can be added to the dashboard.
Pre-Built KPI Widgets
There are four pre-built KPI widgets: Total Cost, Efficiency Score, Efficiency Score (Usage), and Idle Cost. These widgets are displayed on the default dashboard and can be added to any dashboard through the drop-down menu.
Custom KPI Widget
Users can add custom KPI widgets through the drop-down menu to add a "Custom KPI" widget.
Metric Type : Options include Total, CPU, Memory, GPU, Network TX, Network RX, FileSystem, and Persistent Volume. This shows the metrics for specific resource types.
Metric Summary : Options include Cost and Utilization. This indicates whether the KPI is based on cost metrics or utilization metrics.
Metric Allocation : Options include "Fair Share," "Allocated," "Idle," and "Efficiency." This shows whether the allocation is about fair share, allocated, idle, or efficiency of the metric type, and summary.
-
Fair Share : Provisioned resources shared proportionally based on allocation among all tenants.
-
Allocated : Resources allocated to a container; the larger of usage and request.
-
Idle : Resources not allocated and fair shared among tenants; the difference between Fair Share and Allocated.
-
Efficiency : Calculated as Allocated divided by Fair Share.
The combination of metric type, summary, and allocation determines the KPI to be created. Here are some examples:
|
Metric Type |
Metric Summary | Metric Allocation | KPI |
|---|---|---|---|
|
Total |
Cost |
Efficiency | Efficiency Score = Allocated Cost / Fair Share Cost (or Total Cost) |
|
CPU |
Cost | Efficiency | CPU Efficiency Score = Allocated CPU Cost / Fair Share CPU Cost |
|
CPU |
Cost | Fair Share | CPU Fair Share Cost = Cost for the fair share CPU units |
|
CPU |
Cost | Allocated | CPU Allocated Cost = Cost for the allocated CPU units |
|
CPU |
Cost | Idle | CPU Idle Cost = CPU Fair Share Cost - CPU Allocated Cost |
|
CPU |
Utilization | Efficiency | CPU Utilization Efficiency = Allocated CPU Units / Fair Share CPU Units |
|
CPU |
Utilization | Fair Share | CPU Fair Share Units |
|
CPU |
Utilization | Allocated | CPU Allocated Units |
|
CPU |
Utilization | Idle | CPU Idle Units = CPU Fair Share Units - CPU Allocated Units |
These KPIs can be filtered by clusters, namespaces, workload, workload type, container, node, or label keys. Filters are combined with "AND" operations, and only the "equals" operator is allowed.
There are also several chart widgets that can be added to your dashboard.
Pre-Built Chart Widgets
There are four pre-built chart widgets:
Efficiency for Top 10 Idle Cost Clusters
Top 10 Costs by Clusters
Top 10 Least Efficiency Score by Cluster
Total Cost Trend
Custom Chart Widgets
There are three types of custom chart widgets supported:
Custom Time Series: Displays trend information on the queried datasets, based on any combination of metric type, summary, and allocation. It can be grouped by combinations of cluster, namespace, workload, workload type, node, container, or label keys. It also allows ordering by top 10 or bottom 10.
Custom Top/Bottom 10 Widget : Displays queried datasets in a specified order, supporting only vertical bar charts.
Custom Allocated vs Idle : Displays queried datasets for allocated versus idle comparison, usable for both cost, and utilization metrics.
Customization and Layout
Users can easily customize the layout and content of their dashboards by adding, removing, and rearranging widgets. Each widget's settings and filters can be adjusted to meet specific analysis needs, providing a highly flexible and personalized visualization experience.
This guide covers the essential features and customization options available in the new Containers Insight 2.0. By utilizing these dashboards and widgets, users can gain deeper insights into their Kubernetes environments, optimizing cost, utilization, and efficiency.
