We all love today's modern web with lots of API's available, both for retrieving information from various sources, gaining additional insights and for transform and enrich your data. Most API's today are RESTFUL, meaning that they should follow the REST principles. REST is not a standard, it's more a guideline for how …

HPE released it's 4th version of their OneView management appliance late in December. While version 3 was a great deal better than v2 and v1 I have some expectations on this release as well. I think all versions have had value and the new features and functionalities presented has been for the better. Still it wasn't …

For those of you that have read my blog you probably know I've done a series on performance monitoring infrastructure with the help of InfluxDB. InfluxDB is a part of the TICK stack delivered by InfluxData. All components are open-sourced and available. The TICK stack consists of, Telegraf, InfluxDB, Chronograf and …

In our environment we have several HPE Blade Chassis systems. The chassis is managed with the Onboard Administrator (OA) which consists of one or two management modules. Like all other hardware these modules have components that needs firmware to run. And firmware needs to be kept updated to fix bugs, add features, new …

This weekend our primary OneView appliance crashed. This particular OneView appliance handles 10 blade chassis and over 120 blade servers As OneView handles only the management side of the hardware nothing in production was affected by this crash. TLDR; There is a bug in version 3.10.04 which doesn't delete expired …

If you've followed my vSphere performance data blog series you probably have noted that I used InfluxDB as the database for storing the performance data. With over 4 months of performance data in the InfluxDB I've picked up some gotcha's along the way (there's probably more lying around which I've not come over yet). …

Following up on my last post on Automating DRS Groups with PowerCLI I found that we also need to automatically remove VMs and Hosts from a given DRS Group. Although I could have included this in the previous script which creates the groups and adds members I wanted to separate them. There could for instance be times …

In vCenter we have lot's of DRS functionalities. I won't go into all of them here, you'll probably know about most of them already. This blog post will talk about the VM/Host affinity functionality, i.e. rules to keep VMs running one or more specific host(s). There is multiple use-cases for this. You might want to keep …
