Making sure the NFS server allows read-write access to the shared location by the root system account on each cell is the correct way to enable the collection of log bundles from all cells at once. This is because VMware Cloud Director uses the vmware-vcd-support script to collect host log information as well as Cloud Director logs, and this script requires the NFS server to have read-write access to the shared location by the root system account on each cell1. Installing vRealize Log Insight agent on each cell to redirect logs to a centralized location is not a valid option, as vRealize Log Insight is a separate product that does not integrate with VMware Cloud Director. Configuring a syslog server on each of the cells, and requesting the logs from the syslog server is not a feasible option, as it would require manual intervention and coordination to collect the logs from multiple sources. Mapping the log location on the primary cell to a shared folder on each of the other cells in the server group, ensuring they all have read/write rights on the primary is not asufficient option, as it does not address the NFS server configuration that is required for the vmware-vcd-support script to work properly. References: Collecting diagnostic information for VMware Cloud Director (1026312). Preparing the Transfer Server Storage for VMware Cloud Director on Linux.

To get application-related data (metrics) from the VM that vRealize Operations doesn’t collect, the administrator can use the custom script feature of the End Point Operations Management agent. The custom script feature allows the administrator to run custom scripts in the end point VM and collect custom data which can then be consumed as a metric. The administrator needs to install the End Point Operations Management agent on the VM, place the appropriate script to the VM, and then configure the agent to call the script from the Manage Agent location for the VM in vRealize Operations. The script metrics are created under an object called Custom Script which is a single object per end point VM. The administrator can view the output for the specific metric in the All Metrics tab1. The Telegraf agent is not used for custom script monitoring, but for application monitoring using predefined plugins2. The script should not be placed in the vRealize Operation Manager, but in the end point VM. References: 1: Custom Script 2: Application Monitoring

vRealize Operations allows for different node sizes when deploying a cluster to suit various environments and scalability needs. The sizes typically include Small, Medium, and Large, and these sizes determine the capacity and performance of each node in a High Availability configuration.
