In this series of vSAN we have successfully configured vSAN and vSAN Storage policies. vSAN comes with the performance service which is very useful to check and troubleshoot the performance of the vSAN Cluster. The performance service collects and analyzes performance statistics and displays the data in a graphical format. You can use the performance charts to manage your workload and determine the root cause of problems. In this post we will see on How to turn on performance service in vSAN.
When you create a Virtual SAN cluster, the performance service is disabled. Turn on Virtual SAN performance service to monitor the performance of Virtual SAN clusters, hosts, disks, and VMs. When the Virtual SAN performance service is turned on, the cluster summary displays an overview of Virtual SAN performance statistics, including IOPS, throughput, and latency. You can view detailed performance statistics for the cluster, and for each host, disk group, and disk in the Virtual SAN cluster. You also can view performance charts for virtual machines and virtual disks.
Let’s see how to enable the vSAN performance service and how to view vSAN Performance:
Login to vSphere Web Client.
Select your vSAN Cluster.
Go to Monitor Tab > Choose Performance.
For Virtual Machine Consumption matrics you have to enable the performance service.
You can directly click here on “Turn On Now” to enable the performance service.
You can also enable by going into Configure tab.
Go to Configure Tab > Choose Health and Performance.
As you can see that Performance Service is turned Off. To enable the performance service click Edit button.
Check the box to turn on the service and select storage policy.
As you can see that vSAN Performance service is now enabled.
Here you can see the performance of the vSAN Performance using various metrics:
Using this way you can easily enable the vSAN performance service. Once you enable it you can easily troubleshoot the performance related issues by just looking at the vSAN Cluster performance graphs.
