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

Exploring the HPE G2 PDU REST API

Lately I’ve been playing around with the Redfish based REST API in the HPE G2 Metered and Switched Power Distribution Units.

Through the API you are able to pull some details about the PDU as well as different utilization data. Based on your PDUs capabilities you should also be able to control different outlets. My focus has been to pull some details about the PDUs, and to pull the load on the different segments.

As I usually do when I set out exploring an API I was looking for the documentation. Surprisingly there was nothing to be found. The only thing I found was a few lines in the PDU User guide regarding authentication. ...  continue reading

Automate disabling of IPMI over LAN access on HPE iLO

This article will describe how you can disable the IPMI over LAN access on HPE iLO.

The IPMI protocol can present a security vulnerability where the authentication process for IPMI requires a server to send a hash of a user password to the client before authentication. This is not a new vulnerability and since this is a part of the specification of the protocol there is no fix for it besides disabling it or accepting it.

Note that iLO versions 2, 3 and 4 have the IPMI over LAN access enabled by default whereas iLO version 5 has disabled this by default. ...  continue reading

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 ...  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
