 Cloud Proxies are special types of remote collectors that enable vRealize Operations Cloud to collect and monitor data from on-premises data centers. Cloud Proxies establish a one-way communication channel from the on-premises environment to the vRealize Operations Cloud, and they securely upload data to the cloud instance without requiring any inbound ports to be opened on the firewall. Cloud Proxies can support multiple vCenter Server accounts and other management packs, and they provide data persistence and high availability features12. References: 1: Configuring Cloud Proxies in vRealize Operations 2: Managing Cloud Proxies in vRealize Operations

To enable east/west firewall in VMware Cloud Director Tenant Portal, you need to perform the following steps:

• Login to Customer Organization and go to Networking Section of Tenant Portal. This is where you can access the networking capabilities provided by NSX Data Center for vSphere in your VMware Cloud Director organization virtual data center.
• Go to Edge Gateways and enable firewall on one of the Edge Gateways. This will allow you to configure the edge gateway firewall rules for north/south traffic enforcement and perimeter security functionality. You can also enable other services such as NAT, VPN, load balancing, etc. on the edge gateway.
• Go to Networking and enable Distributed Firewall for one of the Network inside the Network section. This will allow you to configure the distributed firewall rules for east/west traffic isolation and access control. You can also apply security policies and groups to the network and the virtual machines within it.

A metric configuration in vRealize Operations is a collection of metrics that you can apply to one or more widgets in a dashboard. A metric configuration allows you to customize the metrics that you want to display on the widgets, and also to define the color, label, unit, and aggregation type for each metric. You can create, edit, or delete metric configurations from the Metric Configuration page in the Administration menu1. A metric configuration is not the same as a metric group, which is a predefined set of metrics that you can select from the widget configuration panel2. A dashboard navigation is a feature that allows you to link one or more widgets or views in a dashboard to another dashboard, and pass the selected object as a filter to the destination dashboard. When a dashboard navigation is created, the destination widgets or views are filtered by the selected object from the source dashboard3. An alert can be created from the Alert list widget, which displays the alerts for the selected object or group of objects in a dashboard. You can create an alert by clicking the Add Alert icon on the widget toolbar, and then selecting the alert definition, the object, and the alert properties4. Dashboards can be added by installing management packs, which are extensions that provide additional monitoring and management capabilities for various solutions and platforms. However, dashboards can also be added by creating custom dashboards, importing dashboards from the VMware Marketplace, or cloning existing dashboards. References: 1: Manage Metric Configurations 2: Select Metrics for Widgets 3: Create Dashboard Navigation 4: Create an Alert from the Alert List Widget : [Create and Configure Dashboards]
