To ensure that vRealize Operations Manager can monitor a newly deployed vSAN cluster within an existing vCenter Server, the administrator should download and install the vRealize Operations Management Pack for vSAN. This management pack provides specific capabilities and integrations required for detailed monitoring and performance management of vSAN environments.
To establish a trust relationship between the existing vRealize Operations cluster and the new nodes, the administrator can use the method of generating passphrases in the administration User Interface of an existing node, and then enter these passphrases when prompted in each new node. Additionally, the administrator can click the Add New Nodes button on the Cluster Management page in the product User Interface of an existing node. These methods ensure the new nodes successfully integrate into the existing cluster.
If the 'Refresh content' option is set to Off, the scoreboard widget may not update to show the new metrics. This setting needs to be enabled to ensure that the widget periodically refreshes and displays the latest data, including the newly configured custom metrics.
vRealize Operations might report that the cluster has 0 days remaining when the actual CPU overcommit ratio is less than the 4:1 configured value because the CPU demand in the cluster is greater than the total CPU capacity. This happens if the cluster's CPU demand consumes all available capacity, leading to an overcommitment situation despite the configured ratio.
From the vRealize Operations Product UI, you can perform various actions on vSphere virtual machines such as deleting virtual machine snapshots, moving virtual machines, and adding vCPUs. These actions help manage and optimize the resources allocated to VMs. Creating snapshots, adding virtual disks, or expanding virtual disks typically require access to vSphere directly rather than being manageable through vRealize Operations.
