Use the Troubleshoot a VM dashboard to troubleshoot performance problems of a single VM.
You can use the dashboard widgets in several ways.
Use the Search for a VM to Troubleshoot widget to view all the VMs in the environment. You can select the VM you want to troubleshoot. You can use the filter to narrow your list based on several parameters, such as name, folder name, associated tag, host, or vCenter Server. After you identify the VM you want to troubleshoot, select it. The dashboard is automatically populated with the relevant data.
Use the About a VM widget to understand the context of the VM. This widget also lends insights to analyze the root cause of the problem or potential mitigations.
Use the Are there Critical Alerts widget to view critical alerts. To see noncritical alerts, click the VM object.
Use the Related Objects widget to view the ESXi host where the VM is now running. This host might not be the ESXi host where the VM was running in the past. You can view the remaining related objects and see whether they might contribute to the problem.
Use the Is the VMs Demand Spiking or Anomalous widget to identify spikes in the VM demand for any of the resources such as CPU, memory, and network. Spikes in the demand might indicate an abnormal behavior of the VM or that the VM is undersized. The memory utilization is based on the Guest OS metric. It requires VMware Tools 10.0.0 or later and vSphere 6 Update 1 or later. If you do not have these products, the metric remains blank.
Use the Is the VM Facing Contention widget to identify whether the VM is facing contention. If the VM is facing contention, the underlying infrastructure might not have enough resources to meet the needs of the VM.
Use the Does the Parent Cluster have Contention widget to view the trend for the maximum CPU contention for a VM within the cluster. The trend might indicate a constant contention within the cluster. If there is contention, you must troubleshoot the cluster as the problem is no longer with the VM.
Use the Does the Parent Datastore have Latency widget to help you correlate the latency at the datastore level with the total latency of the VM. If the VM has latency spikes, but the datastore does not have such spikes, it might indicate a problem with the VM. If the datastore faces latency as well, you can troubleshoot to find out why the datastore has these spikes.
Use the Parent Host and Parent Cluster widgets to view the host and the cluster on which the VM resides.
