vRealize Network Insight provides the approximate capacity and load information of a proxy node and a platform. This limits-based information helps you to prevent the performance and experience issues later.
The capacity is defined as follows:
Single platform with one or more proxy nodes: The capacity of a proxy node or the platform is the number of discovered VMs that it can handle without the degradation of performance.
Cluster setup: The capacity of the platform in a cluster setup is the aggregation of all the capacities of all the platform nodes while the capacity of proxy nodes is considered at the level of an individual node.
Accessing the Capacity Information
The Utilization option on the Install and Support page provides the used capacity for a platform.
The Utilization option under the Collector (Proxy) VMs on the Install and Support page provides the used capacity for each proxy node.
When the number of discovered VMs from the data sources across the deployment exceed the capacity of either the platform or the proxy or both, the validation fails and you will not be allowed to add a vCenter/AWS data source.
To view the discovered VMs for a data source:
In the Accounts and Data Sources page, you can see the number of VMs that have been discovered for a particular data source which is already added and currently active. This column will have a value only if the data source is vCenter or AWS source.
The discovered VM count includes Placeholder and Template VMs. So it can be different from the count of VMs in the product.
