Nutanix Cluster Detail dashboard
The Nutanix Cluster Detail dashboard provides a detailed look into one of the selected Nutanix Acropolis Clusters within the client's BMC Helix Continuous Optimization (HCO) environment. Within the dashboard the following capacity insights will be presented:
- Snapshot of the Current Capacity
- Configuration Metrics collected for the cluster
- Tags applied to the cluster
- Timeseries for metrics being collected for the cluster
- Future Saturation of resources
- Timeseries which visualizes the future saturation
- Virtual Machine Oversubscription
- Spare Virtual Machine Count (estimated number of virtual machines that can be added to the cluster before saturation occurs)
- Associated Hosts
- Associated Storage Pools
- Associated Virtual Machines
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 selected
- Data Resolution → Contains three values: Detail, Hourly, and Daily. This filter changes the data resolution to be used in the timeseries charts.
- Resource Statistic → Contains three values: Average, Max, and 95th Percentile. This filter changes the statistic to be used in the timeseries charts.
Links
Links can be found in the upper right portion of the dashboard. The following links are:

Panels
The Nutanix Cluster Detail dashboard consist of multiple rows and panels that give insight into the capacity and health of the selected Nutanix Acropolis Cluster.
Cluster Summary

IP Address
Shows the assigned IP address for the cluster
Tags
Shows all the tags applied to the Cluster
Counts
Shows the total counts for Hosts, Disks and Virtual Machines.
Active VMs
Shows the total number of VMs that have a last VM status (VM_LAST_STATUS) of "1" (On)
Inactive VMs
Shows the total number of VMs that have a last VM status (VM_LAST_STATUS) of "0" (Off) or NULL (metric does not exist)
CPU Utilization over Time
A chart that shows the CPU Utilization metric over time. This timeseries is affected by the "Data Resolution" and "Statistic" filters. It is also interactive with the Time Range Picker.

CPU
Shows if the cluster CPU resource is Saturated, will be saturated, or will not be saturated. Clicking on this panel will change the Forecast panel below to focus on the CPU forecast.
Memory
Shows if the cluster Memory resource is Saturated, will be saturated, or will not be saturated. Clicking on this panel will change the Forecast panel below to focus on the Memory forecast.
Storage
Shows if the cluster Storage resource is Saturated, will be saturated, or will not be saturated. Clicking on this panel will change the Forecast panel below to focus on the Storage forecast.
Forecast Panel
Initially displays the forecast for the CPU resource. However, this panel is interactive using the Saturation panels above it (CPU, Memory Storage). Clicking on one of the panels above will align this panel with the resource indicated in the panel that was interacted with. This forecast timeseries is also affected by the "Data Resolution" filter, the "Statistic" filter and the Time Range Picker.
