Nutanix Cluster dashboard
The Nutanix Cluster dashboard provides an overview of all the Nutanix Acropolis Clusters within the client's BMC Helix Continuous Optimization (HCO) environment. Nutanix Acropolis Clusters are identified by the HCO entity type "Virtual Cluster - Acropolis". Within the dashboard the following capacity insights are presented:
- Snapshot of the Current Capacity
- Future Saturation
- Virtual Machine Oversubscription
- Spare Virtual Machine Count (estimated number of virtual machines that can be added to the cluster before saturation occurs)
Filters
Filters can be found in the upper left portion of the dashboard. The following filters are:
- Cluster → Filters all panels to only focus on the specified cluster(s) selected
- Time Period → Contains three values: Last 30 Days, Last 7 Days, and Yesterday. This filter changes the aggregation period for the metrics CPU Utilization, Memory Utilization, and Storage Utilization. Ergo, only tables that that have the column CPU Utilization, Memory Utilization, and Storage Space Utilization are affected by this filter.
- Resource Statistic → Contains three values: Average, Max, and 95th Percentile. This filter changes the aggregation statistic for the metrics CPU Utilization, Memory Utilization, and Storage Utilization. Ergo, only tables that that have the column CPU Utilization, Memory Utilization, and Storage Space Utilization are affected by this filter.
Links
Links can be found in the upper right portion of the dashboard. The following links are:
- Nutanix Hosts
- Nutanix Storage Pools
- Nutanix Virtual Machines
- Nutanix Cluster Detail
Panels
The Nutanix Cluster Dashboard consists of multiple panels that give insight into the capacity and health of Nutanix Acropolis Clusters.
Total Cluster Count
Displays the total Acropolis Cluster count found within the client's HCO environment. The total count is affected by the "Cluster" filter.
Not Saturated
Displays the count for all Acropolis Clusters that are predicted to not have future saturation in one or more of the following metrics: CPU Utilization, Memory Utilization, or Storage Space Utilization. The count is affected by the "Cluster" filter.
Future Saturated
Displays the count for all Acropolis Clusters that will have a future saturation in one or more of the following metrics: CPU Utilization, Memory Utilization, or Storage Space Utilization. The count is affected by the "Cluster" filter.
Future Saturated
Displays the count for all Acropolis Clusters that are currently saturated in one or more of the following metrics: CPU Utilization, Memory Utilization, or Storage Space Utilization. The count is affected by the "Cluster" filter.
All Clusters
A cluster overview table with the following details:
Column | Description | Metrics |
Cluster | Name of the Acropolis Cluster. Click on the name to open a new tab to the Cluster Detail dashboard for the respective cluster. | N/A |
IP Address | IP Address of the respective cluster. | NET_IP_ADDRESS |
Timezone | Timezone of the respective cluster. | TIMEZONE |
Host Count | Number of Hosts associated with the respective cluster. | HOST_NUM |
Disk Count | Number of Disks associated with the respective cluster. | DISK_NUM |
VM Count | Number of Virtual Machines associated with the respective cluster. | GM_NUM |
Days to Saturation | Shows whether a cluster has Saturation, Future Saturation, or no Saturation for one or more of the following metrics: CPU Utilization, Memory Utilization, or Storage Space Utilization. Only clusters that are expected to saturate within the next 100 days are considered to have future saturation. Days to Saturation is computed by calculating the slope using the last 30 days of hourly data. | CPU_UTIL, MEM_UTIL, TOTAL_DSTORE_UTIL |
Bottleneck | The metric that is contributing to the current saturation or future saturation shown in the Days to Saturation column. | N/A |
Total Memory | Total Memory value. | TOTAL_REAL_MEM |
CPU Utilization | Aggregated CPU Utilization value. This value is affected by the "Cluster" and "Time Period" filters. | CPU_UTIL |
Memory Utilization | Aggregated Memory Utilization value. This value is affected by the "Cluster" and "Time Period" filters. | MEM_UTIL |
Storage Utilization | Aggregated Storage Utilization value. This value is affected by the "Cluster" and "Time Period" filters. | TOTAL_DSTORE_UTIL |
Oversubscribed VM Ratio
Table that focuses on the oversubscribed Virtual Machines:
Column | Description |
Cluster | Name of the Acropolis Cluster. |
CPU | The VM Oversubscription Ratio for CPU. |
Memory | The VM Oversubscription Ratio for Memory. |
Spare Virtual Machines
Table that focuses on how many more Virtual Machines can be added to cluster before the cluster becomes saturate:
Column | Description |
Cluster | Name of the Acropolis Cluster. |
Spare VM Count | Total number of VMs that can be added before saturation. |
Limiting Resource | The Resource that is the leading contributor when determining the Spare VM Count. This resource is also reflective of the most exhaustive resource for the VMs within the Cluster. |
