vSphere Performance Data – Part 2 – Retrieve data

This is part 2 of my vSphere Performance Data series. Part 1 described the project and my goals with the project.

This post will be my thoughts on retrieving performance data from our vSphere environment. As I described in part 1 our environment consist of 100+ hosts and 4000+ VMs. These are hosted in 3 different vCenters in the same SSO domain (Enhanced Linked Mode). All hosts and vCenters are at version 6. We are in the process of upgrading vCenter to 6.5 as I’ve talked about in a previous post.

Currently we are using Turbonomic in our environment which also retrieves performance data from the vCenters that it uses in it’s main purpose which is to balance the load in our environment. As it retrieves and presents performance data we are using this is our source of perf data in our in-house portals and dashboards. I’ve blogged about this on the Turbonomic community site previously where I talk about how I use their API in our dashboards.
Turbonomic stores their “real-time” data in 10 minute intervals and the trend data is stored hourly with average and peaks.[...] continue reading

vSphere performance data – Part 1

There is lots of posts on retrieving performance data from your vSphere environment (I’ll probably use a lot of them in this series), but here’s my take on it.

My ultimate goal is to build my own database of performance data and have a nice front-end presenting this. I also want to have an API that extracts data from the performance DB which I will use in our in-house portals and dashboards.

This project can be quite big and complex so I will split it in 3 parts:[...] continue reading

.NET core gotcha

Recently I’ve been messing around with the new .NET Core.

I’ve created a class library which I’m using in an ASP.NET Core Web API.

Firstly, at least before 1.1, I couldn’t add a reference to the class library just by giving it the .dll file. I needed to create a NuGet package of my library and publish it to a NuGet feed. I set up a local NuGet feed and added it as a source in VS and were able to add my code. This is all fairly easy.[...] continue reading
