Nodes page in the Kubernetes view
The Nodes page is designed to provide capacity management insights for the Kubernetes nodes. 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 nodes.
Column name | Meaning | Statistics | Metrics |
|---|---|---|---|
Node | Name of the node. Clicking on one of the nodes in this column takes you to the Node details page in the Kubernetes view. | Not Applicable | |
Cluster | Name of the cluster that the node is running on. | Not Applicable | |
Days To Saturation | Estimated number of days before one of the resources (CPU or Memory) of the node breaches the configured warning threshold. | Average of the hourly time series values are used for the estimation calculation | IND_DAYS_TO_SATURATION |
CPU # | Number of CPU cores currently configured for the node. | Last Value | CPU_NUM |
CPU Used [cores] | Total CPU used by the node expressed in cores. | 95th percentile | CPU_USED_NUM |
CPU Request [cores] | Amount of CPU that the system will guarantee for the node. | Last Value | CPU_REQUEST |
CPU Limit [cores] | Maximum CPU cores that the node will be allowed to use. | Last Value | CPU_LIMIT |
CPU Used vs Capacity [%] | Percentage of CPUs actually used with respect to CPU capacity (number of CPUs) | 95th percentile | CPU_UTIL |
CPU Request vs Capacity [%] | Percentage of CPUs requested with respect to CPU capacity (number of CPUs) | 95th percentile | CPU_REQUEST_CAPACITY |
CPU Used vs Limit [%] | Percentage of CPU used with respect to the CPU limit. | 95th percentile | CPU_UTIL_LIMIT |
CPU Limit vs Capacity [%] | Percentage of CPU limit with respect to CPU capacity (number of CPUs). | 95th percentile | CPU_LIMIT,CPU_NUM |
Memory [GB] | Total memory configured for the node. | Last Value | TOTAL_REAL_MEM |
Mem Used [GB] | Total memory used by the node. | 95th percentile | MEM_USED |
Mem Real Used [GB] | Real memory used by the node. | 95th percentile | MEM_REAL_USED |
Mem Limit [GB] | Maximum amount of memory that the node is allowed to use. | Last Value | MEM_KLIMIT |
Mem Request [GB] | Amount of memory that the system will guarantee for the node. | Last Value | MEM_REQUEST |
Mem Used vs Capacity [%] | Percentage of memory actually used with respect to memory capacity (total memory) | 95th percentile | MEM_UTIL |
Mem Real Used vs Capacity [%] | Percentage of real memory actually used with respect to memory capacity (total memory) | 95th percentile | MEM_REAL_UTIL |
Mem Request vs Capacity [%] | Percentage of memory requested with respect to memory capacity (total memory) | 95th percentile | MEM_REQUEST_CAPACITY |
Mem Real Used vs Limit [%] | Percentage of real memory used with respect to memory limit. | 95th percentile | MEM_REAL_USED,MEM_KLIMIT |
Mem Limit vs Capacity [%] | Percentage of memory limit with respect to memory capacity (total memory). | 95th percentile | MEM_KLIMIT,TOTAL_REAL_MEM |
File System Size [GB] | Total file system configured for the node. | Last Value | TOTAL_FS_SIZE |
File System Util [%] | Percentage of file system actually used with respect to file system capacity (total file system). | 95th percentile | TOTAL_FS_UTIL |
Pod # vs Pod Max [%] | Percentage of pod already created | Last Value | KPOD_NUM, KPOD_NUM_MAX |
Bottleneck | 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 key metrics related to the CPU.
Memory
The Memory tabs presents the most important metrics related to the memory.
Detailed information about a specific node
After you click on the node in the Node column, the Node details page is displayed. You can use the sorting and filtering options on the page to find a specific node.
Section or Panel | Description |
|---|---|
General details section | General details, such as node name and type are displayed. The type is Kubernetes - Node. |
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, memory, and network data, and number of pods of the node. Core metrics for the selected entity are displayed as analysis charts, depending on available data. |
Configuration Details tab | The configuration matrix for the selected node. |
