After reviewing various performance charts at a cluster level, an administrator found an individual VM impacting overall performance of the vSAN cluster.
What feature should be used to introspect multiple performance metrics of a single virtual machine?
To introspect multiple performance metrics of a single virtual machine, IOInsight should be used. IOInsight allows administrators to view detailed I/O performance characteristics of virtual machines within a vSAN cluster, enabling better capacity planning and performance tuning.
Keyword is single virutal machine. Not environment. IOInsight allows you to select and view I/O performance metrics of virtual machines in a vSAN cluster. By understanding the I/O characteristics of VMs, you can ensure better capacity planning and performance tuning. https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.vsan-monitoring.doc/GUID-3ABCB8EA-1FC7-40A4-B834-C9FEDF02A902.html
