Namespaces page in the Kubernetes view - Documentation for BMC TrueSight Capacity Optimization 20.02
Matthew Perez Each page contains three different second-level tabs each of which presents capacity and efficiency KPIs related to the resources relevant for the analyzed entity:
Capacity
The first tab "Capacity" is designed to provide a summary of the most important KPIs for managing capacity of Kubernetes Namespaces.
The table below summarize the information that is provided by the tab.
Column name | Meaning and Calculation |
|---|---|
Namespace | Name of the namespace |
Cluster | Name of the Cluster |
Status | Indicator of the resource's status (*) |
CPU Used vs Request [%] | Percentage of CPU used with respect to the CPU request, calculated as CPU_USED_NUM/CPU_REQUEST |
CPU Request vs Quota [%] | Percentage of CPU request with respect to the namespace CPU request quota, calculated as CPU_REQUEST/CPU_REQUEST_MAX |
Mem Request vs Quota [%] | Percentage of memory request with respect to the namespace memory request quota, calculated as MEM_REQUEST/MEM_REQUEST_MAX |
Mem Limit vs Quota [%] | Percentage of memory limit with respect to the namespace memory limit quota, calculated as MEM_LIMIT/MEM_LIMIT_MAX |
| CPU Limit vs Quota | calculated by CPU_REQUEST/CPU_REQUEST_MAX |
| CPU USED | Number of cores that is used (CPU_USED_NUM) |
| CPU Request | Amount of CPU (cores) that will be allowed to use (CPU_REQEST) |
| CPU Limit | Amount of CPU (cores) that will be allowed to use (CPU_LIMIT) |
| CPU USED (mCores) | Number of millicores that is used (CPU_USED_NUM) |
| CPU Request (mCores) | Amount of CPU (millicores ) that will be allowed to use (CPU_REQEST) |
| CPU Limit (mCores) | Amount of CPU (millicores ) that will be allowed to use (CPU_LIMIT) |
| Mem Request | Amount of memory request (MEM_REQUEST) |
Mem Used | Amount of memory used (MEM_USED) |
| Mem Limit | Amount of memory limit (MEM_KLIMIT) |
Pod # vs Quota [%] | Percentage of pods with respect to memory quota |
Bottleneck Resource | First resource to saturate |
KPOD_NUM | Number of pods |
KPOD_NUM_MAX | Max number of pods |

CPU
The CPU tab presents the most important metrics related to the CPU. The column definition is defined in the table below.
Column name | Meaning and Calculation |
|---|---|
Namespace | Name of the namespace |
Cluster | Name of the cluster |
Status | Indicator of the resource's status |
Days To Saturation | Days before the resource is saturated |
| CPU USED | Number of cores that is used (CPU_USED_NUM) |
| CPU Request | Amount of CPU (cores) that will be allowed to use (CPU_REQEST) |
| CPU Limit | Amount of CPU (cores) that will be allowed to use (CPU_LIMIT) |
Quota Request | Quota set for the CPU request resource (CPU_REQUEST_MAX) |
Quota Limit | Quota set for the CPU limit resource (CPU_LIMIT_MAX) |
| CPU USED (mCores) | Number of millicores that is used (CPU_USED_NUM) |
| CPU Request (mCores) | Amount of CPU (millicores ) that will be allowed to use (CPU_REQEST) |
| CPU Limit (mCores) | Amount of CPU (millicores ) that will be allowed to use (CPU_LIMIT) |
Quota Request (mCores) | Quota set for the CPU request resource (CPU_REQUEST_MAX*1000) |
Quota Limit (mCores) | Quota set for the CPU limit resource (CPU_LIMIT_MAX*1000) |
CPU Used vs Request [%] | Percentage of CPU used with respect to the CPU request (CPU_UTIL_REQUEST) |
| CPU Used vs Limit [%] | Percentage of CPU used with respect to the CPU Limit (CPU_UTIL_LIMIT) |
CPU Request vs Quota [%] | Percentage of CPU request with respect to the namespace CPU request quota, calculated as CPU_REQUEST/CPU_REQUEST_MAX |
CPU Limit vs Quota [%] | Percentage of CPU limit with respect to the CPU limit quota, calculated as CPU_LIMIT/CPU_LIMIT_MAX |
Bottleneck | First resource to saturate |

Memory
The Memory tabs presents the most important metrics related to the memory. The column definition is defined in the table below.
Column name | Meaning and Calculation |

Cluster | Name of the Cluster |
Status | Indicator of the resource's status |
Days To Saturation | Days before the saturation of the physical resources |
| Quota Request | Quota set for the Memory request resource (MEM_REQUEST_MAX) |
Quota Limit | Quota set for the Memory limit resource (MEM_LIMIT_MAX) |
Mem Used [GB] | Amount of memory used (MEM_USED) |
Mem Request [GB] | Amount of memory request (MEM_REQUEST) |
Mem Limit [GB] | Amount of memory limit (MEM_KLIMIT) |
Mem Used vs Request [%] | Percentage of memory used with respect to memory request (MEM_UTIL_REQUEST) |
| Mem Used vs Limit [%] | Percentage of memory used with respect to memory limit (MEM_UTIL_LIMIT) |
Mem Request vs Quota [%] | Percentage of memory request with respect to memory quota, calculated as MEM_REQUEST/MEM_REQUEST_MAX |
Mem Limit vs Quota [%] | Percentage of memory limit with respect to memory quota, calculated as MEM_KLIMIT/MEM_LIMIT_MAX |
Bottleneck | First resource to saturate |
| MEM_REAL_UTIL | Total used memory not including cache |
