Opvizor Performance Analyzer New vSAN 6.7 Performance Analysis

VMware vSAN 6.7 has incredible performance improvements, especially over legacy versions of vSAN. For a VMware administrator, especially with larger environments, keeping a handle on potential performance bottlenecks and other performance hotspots can be challenging. VMware vSAN has already included some really great basic troubleshooting tools built right into the vSAN interface in the vSphere client, however, for more in depth troubleshooting, administrators will want to dig deeper into the vSAN infrastructure. You can certainly have really great success with vSAN Observer as we have covered here. However, as we have already covered here, there is a great overall performance tool that now covers VMware vSAN in much greater depth and detail. Let’s take a look at Opvizor Performance Analyzer New vSAN 6.7 Performance Analysis and see the new dashboards that have been added to make analyzing vSAN performance much easier and intuitive.

If you haven’t heard about Opvizor, it is a self-contained, downloadable appliance that contains everything you need to analyze the performance of your VMware vSphere environment. The appliance is relatively lightweight at under 1 gig or so. It deploys using the standard OVA/OVF deployment process.

So very quickly, you can get up and running gathering key performance indicators in your VMware vSphere environment.  At a glance with the play boards, you can get a look at any potential problem areas in the overall vSphere environment.

With the latest patch rollup, version 4.9.2, Opvizor now has new and improved statistics and performance analysis of VMware vSAN, including the latest version, VMware vSAN 6.7!

Applying the Opvizor 4.9.2 Update

Applying the update if you already are running Opvizor is very simple.  Under the Admin interface, you simply upload the patch and apply the update.  Opvizor recommends creating a virtual machine snapshot of the appliance before applying the update.
