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 | Statistics | Metrics |
|---|---|---|---|
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. | Not Applicable | |
Cluster | Name of the cluster the namespace belongs to. | Not Applicable | |

CPU Limit [cores] | Maximum CPU cores that the node will be allowed to namespace. | Last Value | CPU_LIMIT |
CPU Request vs Quota [%] | Percentage of CPU request with respect to namespace CPU request quota. | Last Value | CPU_REQUEST,CPU_REQUEST_MAX |
CPU Limit vs Quota [%] | Percentage of CPU limit with respect to the namespace CPU limit quota. | Last Value | CPU_LIMIT, CPU_LIMIT_MAX |
Mem Used [GB] | Total memory used by the namespace. | 95th percentile | MEM_USED |
Mem Limit [GB] | Maximum amount of memory that the namespace is allowed to use. | Last Value | MEM_LIMIT |
Mem Request [GB] | Amount of memory that the system will guarantee for the namespace. | Last Value | MEM_REQUEST |
Mem Request vs Quota [%] | Percentage of memory request with respect to memory quota. | Last Value | MEM_REQUEST, MEM_REQUEST_MAX |
Mem Limit vs Quota [%] | Percentage of memory limit with respect to memory quota. | Last Value | MEM_KLIMIT, MEM_LIMIT_MAX |
Pod # vs Quota [%] | Percentage of pods with respect to memory quota. | Last Value | KPOD_NUM, KPOD_NUM_MAX |
Bottleneck Resource | Name of the resource that has either saturated or will saturate in the next 90 days. | Based on IND_DAYS_TO_SATURATION | IND_BNECK_RESOURCE |
CPU
The CPU tab presents the most important metrics related to the CPU.
Column name | Meaning | Statistics | Metrics |

Cluster | Name of the cluster the namespace belongs to. | Not applicable | |
Days To Saturation | Estimated number of days before CPU of the namespace is predicted to breach the configured warning threshold. | Average of the hourly time series values are used for the estimation calculation | IND_DAYS_TO_SATURATION[CPU] |
Quota Request | Quota set for the CPU request resource. | Last Value | CPU_REQUEST_MAX |
Quota Limit | Quota set for the CPU limit resource. | Last Value | CPU_LIMIT_MAX |
CPU Used [cores] | Total CPU used by the namespace expressed in cores. | 95th percentile | CPU_USED |
CPU Request [cores] | Amount of CPU that the system will guarantee for the namespace. | Last Value | CPU_REQUEST |
CPU Limit [cores] | Maximum CPU cores that the node will be allowed to namespace. | Last Value | CPU_LIMIT |
CPU Used vs Request [%] | Percentage of CPU used with respect to the CPU request. | 95th percentile | CPU_UTIL_REQUEST |
CPU Request vs Quota [%] | Percentage of CPU request with respect to CPU request quota | Last Value | CPU_REQUEST,CPU_REQUEST_MAX |
CPU Limit vs Quota [%] | Percentage of CPU limit with respect to the CPU limit quota | Last Value | CPU_LIMIT, CPU_LIMIT_MAX |
Memory

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. |
