 The support bundle that the customer should send that fits the bandwidth constraints is the light-support bundle from all nodes. A support bundle is a collection of logs, configuration files, and diagnostic information that can be used by VMware support to troubleshoot and resolve issues with vRealize Operations1. A support bundle can be generated from the Admin UI of vRealize Operations, and it can include information from the primary nodes, the replica nodes, and the remote collectors2. A support bundle can be either full or light, depending on the amount and type of information that is included. A full-support bundle contains all the logs, configuration files, and diagnostic information that are available, and it is recommended for most cases. A light-support bundle contains only the essential logs, configuration files, and diagnostic information that are needed for basic troubleshooting, and it is recommended for cases where the bandwidth is limited or the issue is not complex3. A light-support bundle is smaller in size than a full-support bundle, and it can be generated faster and transferred easier. A light-support bundle from all nodes includes the information from the primary nodes, the replica nodes, and the remote collectors, and it can help VMware support to identify the cause of the erratic behavior and the role of the remote collectors. A full-support bundle from the primary nodes only (option A) or a light-support bundle from the primary nodes only (option B) are not the best choices, as they do not include the information from the replica nodes and the remote collectors, which may be relevant for the issue. A full-support bundle from all nodes (option C) is not the best choice, as it is larger in size than a light-support bundle, and it may exceed the bandwidth constraints or take longer to generate and transfer. References:
