This report forecasts how many days remain before the level of resource utilization reaches the specified threshold values. The report allows you to analyze the following resource utilization parameters: CPU, memory, datastore free space, read and write rates.
The Summary section provides an overview of the current state of your infrastructure (the total number of hosts, datastores and VMs), displays 5 clusters and standalone hosts that will run out of CPU and memory resources sooner than other clusters and hosts, and shows recommendations on resource allocation.
In the Details section, for each host included in the report scope, the report displays host hardware configuration and resource usage, analyzes historical performance data for the specified period in the past to calculate the performance utilization trend, and provides recommendations on how to keep the resource utilization below the specified thresholds.
Use Case
The report provides recommendations on appropriate resource allocation to help you rationally plan your resources and prevent possible resource shortfalls.
Report Parameters
Scope: defines a virtual infrastructure level and its sub-components to analyze in the report.
Datastores: defines a list of datastores to analyze in the report.
Analyze performance data for: defines a time period in the past for which historical performance data will be used to calculate the performance trend.
Make planning for: defines a time period in the future for which performance data will be used to forecast resource usage trend.
CPU utilization limit (%): defines the CPU usage threshold as a percentage of total cluster CPU resources.
Memory utilization limit (%): defines the used memory threshold as a percentage of total cluster memory resources.
Max utilization per datastore (%): defines the maximum amount of space in use on a datastore.
Min free space per datastore (GB): defines the minimum amount of free space left on a datastore.
Max read/write rate per datastore (MBps): defines the maximum read and write rates per second for a datastore.
Business hours: defines time of a day for which historical performance data will be used to calculate the performance trend. All data beyond this interval will be excluded from the baseline used for data analysis.
