Today we're going to take a brief look at how you can use Foglight for virtualization to help better manage your vSAN environment.
When we log into Foglight, we land on the environment overview page. This shows us any alarms in our environment across VM ware, hyper V, and open stack, as well as our virtual machine health, any resource optimizations that we can also make to help optimize our environment. Right now I want to pay particular attention to a new VM I've created that's running on a new vSAN environment. So let's take a look.
If I click on this bookmark I've made, I can now see the VM that I've just made all on the vSAN, as well as this particular vSAN topology tab, which allows me to see the disk groups that it's running on and the ray configuration of each disk group. So we can see VM home and the two disk groups that it's running on. If I expand a particular disk group, we'll be able to see the disk that that VM is running on, as well as the host that that's related to. We can see this particular disk that's being used, and know what the frequent rates that go into it and any alarms that might be active, indicating that we have an issue with this particular disk. Right now, this all looks good.
So let's take a look at the host. By clicking on the host, I can see just the ESX server. And we've also got the familiar vSAN topology tab. And I can still see VM-10 and I can see that there is one virtual machine running on his host, and we've got that selected. I can also expand this again and see the disk information. So if I expand VM-10, I can once again start seeing which disk is running on which particular disk groups.
Now if you've got more than one VM running on the ESX host, which, in real life not in a lab environment, is going to be the case, all I want is to see all of those VMs and filter out the ones that we don't want to see. So let's look at this particular ESX server . 111. When I land on that ESX host, I'll be able to see, once again, all of the VMs in my environment, as well as the disk groups that they're running on. I can see there's a total six virtual machines, and all are selected. If for instance, I only want to see VM 15 and 26, I can select these and filter down to view just those VMs. Once a filter is applied, I can see on the screen the disk groups and the disks that they use.
