Welcome to VMworld

VMworld 2018 comes to an end

VMworld 2018 is over. As always I’m leaving with lots of great impressions and lots of content to digest and further explore over the coming weeks.

I think it has been even clearer after this year that VMware is focusing on their Cloud strategy together with partners like AWS and IBM, that vSAN is the storage solution they want you to go forward with and that together with NSX this will be the base for the future.

It was also interesting that only since last year the focus on Containers and Kubernetes has really picked up the pace with lots of new offerings and solution as well as the acquisition of Heptio.… continue 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

Industrialising remote offices with VMware vSAN

Recently we received lots of new hardware destined for a customer that has multiple locations world-wide.

They need a robust server solution for their production environments locally. The environment is small in terms of number of VMs, but there is high demands on the environment and we need local hardware at the sites as the connections to these sites varies and they are not fast enough at all times.

Lots of racks

Our solution for these locations was to deploy a small vSAN environment at each site together with the local network gear they need. While performance and stability being the key factors in the project we also had to have cost in mind (as always).… continue reading

vSphere Performance data – New vSphere plugin for Telegraf

Recently there was a new release of Telegraf, a monitoring agent from the guys that built InfluxDB. This new version, 1.8.0, comes with a plugin for vSphere which I’m pretty excited about!

Previously I’ve been testing Telegraf for monitoring some Linux VMs and also my InfluxDB servers and the agent works as expected and it’s as easy to use as the other products in the TICK stack from Influx.

If you’ve followed my blog series about building a monitoring solution for vSphere and other infrastructure components you know that I’ve pulled metrics with PowerCLI scripts. With this new plugin to Telegraf I want to see if I can use this as a replacement.… continue reading

Speaking at VMworld Europe 2018

The schedule builder for VMworld Europe 2018 in Barcelona is finally live and sessions can be scheduled.

For the first time I will have a session at VMworld, as one of the vBrownBag/VMTN community sessions, and I’m really excited about this.

It is very cool that these community sessions are available in the schedule builder and can be scheduled as other sessions. My session is:

Realtime Performance Monitoring – For FREE [VMTN5524E]

The session will be a quick presentation of the work I did through my Performance monitoring blog series. I have only 30 minutes so I won’t be able to cover all of it, but hopefully I will be able to focus on the most important parts and that I can demo some of it.… continue reading

HPE iLO affects ESXi management agents – hosts in “not responding”

The last months we have had several issues with ESXi hosts going in a “Not responding” status. The VMs are still active and online in this scenario, but the ESXi cannot be managed. This also affets backup as it won’t be able to reach the VMs through the APIs.

Previously we have normally just restarted the management agents on the host and it has been able to connect to vCenter and after this we have managed to migrate the VMs off the host. Lately this hasn’t worked and we have been forced to boot the host with the result of the VMs getting rebooted by HA and eventually started on a different host.… continue reading

Exploring monitoring endpoints in the vCenter Server Appliance (VCSA) REST API

For a long time, actually since we migrated to the VCSA in 6.5 last year, I’ve wanted to utilize the REST API in the appliance to have some monitoring of them.

For several reasons I’ve had to put that on hold, one of them being that there seems to be something wrong with the back-end authentication calls. I get authentication errors on certain calls no matter which user I am logged in with (also the vsphere.local admin account).

 

After deciding to check it more closely I eventually found a few errors in the VCSA logs which in turn led me to this article by Ryan Harris.… continue reading

You’re in!

This month I was accepted as a vExpert for the first time! In total VMware announced 233 new vExperts this summer for their second half announcement in the program.

The vExpert program is not a technical certification. VMware states: The judges selected people who were particularly engaged with their community and who had developed a substantial personal platform of influence in those communities.

I am very proud and honored to be included in this community. I have for a long time consumed the content produced by many of these great contributors and talented individuals and now to be a part of the same is humbling but also a great achievement for me.… 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

Upgrading to HPE OneView 4.1 – Failed!

After the release of the new and shiny version 4.1 of HPE OneView we have tried to upgrade one of our (smaller) OneView instances.

The update process is usually quite straight forward and it gets better in every release. The upgrade to 4.0 from 3.x had some issues with certificate handling post-upgrade, but it was manageable.

The upgrade from 4.0 to 4.1 should not be affected by the same so I had great hopes about a smooth upgrade.

After reading up on the Release notes and Install/upgrade instructions we proceeded with the upgrade process. We are upgrading from 4.0.07.

First of is to do a backup of the appliance.… continue reading
