Enable optional privileges for resource optimization

Enable optional privileges for resource optimizationTo enable automated resource optimization, the service account requires additional privileges. The following permissions should be added to the Role you just created.

Credentials required for optimization

Foglight Resource Optimizer provides recommendations for changes in the VMware® environment to make more efficient use of resources. As a prerequisite, a VMware agent must be configured with a user that has elevated privileges, beyond the read-only privileges required for monitoring.For a list of privileges required for the VMware agent, see section “Configuring Monitoring Agents for Data Collection” in the Foglight for VMware User and Reference Guide.Credentials groups for resource optimization can be defined using the Credentials tab.

Data collection

The Optimizer dashboard automatically displays the virtual machine hosts (VMware® target machines) that Foglight or Foglight for Virtualization, Enterprise Edition monitors, for which resource optimization recommendations are provided. No further setup is required.

Each Federated Child should be configured to monitor its own unique environment. There should be no overlap between the monitored environments, such that no two Federated Children are monitoring the same nodes (VM, Server, Datastore, etc.). Incorrect configuration results in topology churn on the Foglight Federation Master.
