 The frequency at which new services are discovered when using Service Discovery in vRealize Operations is every 5 minutes. Service Discovery is a feature of vRealize Operations that allows the administrator to discover and monitor the applications and services running on the virtual machines in the environment1. Service Discovery can be performed using two methods: credential-less and credential-based. Credential-less Service Discovery uses VMware Tools to query the guest operating system for the list of running processes, and then matches them with a predefined set of signatures to identify the applications andservices2. Credential-based Service Discovery uses the credentials provided by the administrator to log in to the guest operating system and run commands or scripts to discover the applications and services3. Credential-less Service Discovery collects the information about the services running inside the guest every five minutes4. Credential-based Service Discovery collects the information about the services running inside the guest every 24 hours5. Therefore, the frequency at which new services are discovered when using Service Discovery in vRealize Operations depends on the method used, but the most frequent one is every 5 minutes for credential-less Service Discovery. References:

A support bundle is a collection of log and configuration files that can help troubleshoot a vROps issue. To create a support bundle, the system administrator can use the vROps UI and select the option to create a light or full support bundle. A light support bundle includes 24 hours of logs, while a full support bundle includes all available logs and configuration files. For an intermittent issue that occurred in the last 12 hours, a light support bundle should be sufficient to collect the relevant information. The system administrator can also select the cluster nodes that need to be evaluated for support, and download the support bundle in ZIP format for analysis or sending to VMware Technical Support1. The other options are not recommended or efficient ways to collect the relevant information. Collecting the vCenter and vROps primary node logs using SSH and the vm-support utility would not include the logs from the other vROps nodes, and would require manual steps to gather and compress the files. Using the vROps UI to create a full support bundle for ESXi, vCenter, and primary vROps nodes would include unnecessary and excessive data that could slow down the process and consume more disk space. Using SSH to copy the log files from each of the vROps nodes from /var/log/warn & /var/log/messages locations would also require manual steps to gather and compress the files, and would not include the configuration files that could be useful for troubleshooting. References: 1: Create a vRealize Operations Support Bundle

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.
