Namespaces page in the Kubernetes view
The Namespaces page is designed to provide capacity management insights for the Kubernetes Namespaces.
Each page contains additional tabs, each of which presents capacity and efficiency KPIs related to the resources relevant for the analyzed entity. By default, some columns are hidden. You can show or hide columns using the action menu
that is located next to the table title.
Capacity
The Capacity tab is designed to provide a summary of the key KPIs for managing capacity of Kubernetes Namespaces.
Column name | Meaning |
|---|---|
Namespace | Name of the namespace. Clicking on one of the nodes in this column takes you to the Namespace details page in the Kubernetes view. |
Cluster | Name of the cluster the namespace belongs to. |
| Days To Saturation | Estimated number of days before one of the resources (CPU or Memory) of the namespace breaches the configured warning threshold. If the resource usage has already exceeded thresholds, it displays Saturated. |
| CPU Used [cores] | Total CPU used by the namespace expressed in cores. |
| CPU Request [cores] | Amount of CPU that the system will guarantee for the namespace. |
| CPU Limit [cores] | Maximum CPU cores that the node will be allowed to namespace. |
CPU Request vs Quota [%] | Percentage of CPU request with respect to namespace CPU request quota. |
CPU Limit vs Quota [%] | Percentage of CPU limit with respect to the namespace CPU limit quota. |
| Mem Used [GB] | Total memory used by the namespace. |
| Mem Limit [GB] | Maximum amount of memory that the namespace is allowed to use. |
| Mem Request [GB] | Amount of memory that the system will guarantee for the namespace. |
Mem Request vs Quota [%] | Percentage of memory request with respect to memory quota. |
Mem Limit vs Quota [%] | Percentage of memory limit with respect to memory quota. |
Pod # vs Quota [%] | Percentage of pods with respect to memory quota. |
Bottleneck Resource | The resource that is predicted to saturate first. |
CPU
The CPU tab presents the most important metrics related to the CPU.
Column name | Meaning |
|---|---|
Namespace | Name of the namespace. Clicking on one of the nodes in this column takes you to the Namespace details page in the Kubernetes view. |
Cluster | Name of the cluster the namespace belongs to. |
| Days To Saturation | Estimated number of days before CPU of the namespace is predicted to breach the configured warning threshold. If the resource usage has already exceeded thresholds, it displays Saturated. |
| Quota Request | Quota set for the CPU request resource. |
Quota Limit | Quota set for the CPU limit resource. |
| CPU Used [cores] | Total CPU used by the namespace expressed in cores. |
| CPU Request [cores] | Amount of CPU that the system will guarantee for the namespace. |
| CPU Limit [cores] | Maximum CPU cores that the node will be allowed to namespace. |
CPU Used vs Request [%] | Percentage of CPU used with respect to the CPU request. |
CPU Request vs Quota [%] | Percentage of CPU request with respect to CPU request quota |
CPU Limit vs Quota [%] | Percentage of CPU limit with respect to the CPU limit quota |
Bottleneck | The resource that is predicted to saturate first. |
Memory
The Memory tabs presents the most important metrics related to the memory.
Column name | Meaning |
|---|---|
Namespace | Name of the namespace. Clicking on one of the nodes in this column takes you to the Namespace details page in the Kubernetes view. |
Cluster | Name of the cluster the namespace belongs to. |
| Days To Saturation | Estimated number of days before memory of the namespace is predicted to breach the configured warning threshold. If the resource usage has already exceeded thresholds, it displays Saturated. |
| Quota Request | Quota set for the memory request resource. |
Quota Limit | Quota set for the memory limit resource. |
| Mem Used [GB] | Total memory used by the namespace. |
| Mem Request [GB] | Amount of memory that the system will guarantee for the namespace. |
| Mem Limit [GB] | Maximum amount of memory that the namespace is allowed to use. |
Mem Used vs Request [%] | Percentage of memory used with respect to memory request. |
Mem Request vs Quota [%] | Percentage of memory request with respect to memory quota. |
Mem Limit vs Quota [%] | Percentage of memory limit with respect to memory quota. |
Bottleneck | The resource that is predicted to saturate first. |
Detailed information about a specific namespace
After you click on the namespace in the Namespace column, the Namespace details page is displayed. You can use the sorting and filtering options on the page to find a specific namespace.
| Section or Panel | Description |
|---|---|
| General details section | General details, such as namespace name and type are displayed. The type is Kubernetes - Namespace. |
| Related Information panel | Clicking the links in the Related Information panel displays the other information such as image analysis. |
| Summary tab | A quick graphical summary of the CPU and memory data, and pod number and pod status of the namespace. Core metrics for the selected entity are displayed as analysis charts, depending on available data. |
| Configuration Details tab | The configuration matrix for the selected namespace. |
