Slides and script from VMUG session in December

I had the pleasure of giving a talk about how to do monitoring of the vCenter Server during the VMUG Oslo meeting in December. The session was an extension of what I presented during the VMUG meetings in May and the vBrownbag session during VMworld Europe.

The demos showed how we can get health status and metrics from a vCenter Server Appliance utilizing the new REST APIs shipped in 6.5 and 6.7. During the session I built out a Grafana dashboard with version and uptime information about the vCenter, the health status, vCenter service status, disk utilization and CPU/Memory utilization.

Detailed information about how I’ve built out these dashboards can be found here.… continue reading

vSphere Performance – vCenter Server Appliance (VCSA) monitoring

This post is a (late) follow-up on a previous post I did about exploring the monitoring endpoints of the vCenter Server Appliance (VCSA), and an addition to the vSphere Performance blog series.

Now we will add performance metrics and health status of the VCSA to our monitoring solution. We’ll utilize the REST APIs in vCenter and feed the data into our Influx database and visualize it in Grafana.

In vCenter we have the Appliance Management page also refered to as the VAMI. We will use this as a blueprint of what we want to visualize, but we’ll try to fit the important parts into a single Grafana dashboard.… continue reading

Extending the firmware repository in HPE OneView

This is a short post on how to extend the internal firmware repository in HPE OneView.

The procedure is documented in the installation guide for 3.0, but if you are like me chances are that you don’t have that lying around so I thought I’d write up a short post on it for future reference.

The process is pretty straight forward:

  • Shut down the appliance
  • Extend the hard disk to 275GB*
  • Start the appliance
  • The repository should be extended, if not do a manual restart
  • Note that the disk needs to be minimum 275 GB for the repository to be extended, and that anything more than 275GB will be wasted space

For reference, check out this HPE Advisorycontinue reading

Upgrading the VCSA and converting to embedded PSC

This week I’ve been playing in our vCenter lab and tested the upgrade to 6.7 U1 and also changing the deployment type to vCenter with embedded PSC.

I must say that the vCenter team has done a great job on the upgrade process over the last year. Both our migration from the Windows vCenter to the VCSA as well as the upgrade of a VCSA works well and there are lots of great documentation.

Our lab deployment consists of one vCenter VCSA running 6.7 and an external PSC. Both have been migrated from a Windows vCenter and later upgraded to 6.7.… continue reading

VCSA 6.7 Upgrade error – The mystery of how the installer connected to the wrong VM

When trying to upgrade our lab vcenter from 6.5 to 6.7 this week we encountered a strange error.

Our lab environement is running vSphere 6.5 on VCSA and we are running with an external PSC. So when starting the upgrade of the PSC I got an error early in the process, while connecting to the source VCSA.

Error when deploying appliance

 

I had remembered that I’ve seen some strange errors before if the root password of the appliance was expired. This was not the case here, but I did change the password and reboot the appliance to see if that solved the problem.

As I got the same error on the next try I tested an earlier 6.7 (the GA) version to see if that had the same error and it failed on that as well.… continue reading

vSphere 6.5 upgrade – vCenter server. Check your database size

In my last post about upgrading vCenter to 6.5 I’ve outlined the steps I needed to do for the migration. Both pre-migration, the actual migration and some post-migration steps.

Today we were about to upgrade/migrate one of our oldest and biggest vCenters which presented some additional steps to consider for the pre-migration checks and tasks. This is also described in the VMware documentation so it shouldn’t be a surprise to those reading that before migrating.

Anyways, we started the migration and all seemed fine until the Deployment size of the Appliance were shown. The installer only gave one option, the x-large.… continue reading

vSphere 6.5 upgrade – vCenter server

In a previous post I talked about the upgrade of our vSphere environment. The first post described the upgrade and migration of the Platform Services Controller (PSC) from a version 6 running on Windows to a 6.5 Appliance.

Our upgrade path would be PSC -> vCenter -> Hosts. Our environment consists of several vCenters so this will take some time and we might upgrade hosts in a vCenter that has been upgraded to 6.5 before we finish upgrading all vCenters to 6.5

With that, let’s look at upgrading a vCenter server to 6.5!

There are several preparations that needs to be considered before migrating:

  • Read documentation!
