Real-time view of ESX Logs in the Service Console

A collegue of mine just gave a me a few tips on how to view the logfiles on an ESX Host in Real-time. Normally I would export all of the logs via the VIC or the vm-support command. But this limits me to only seeing what has happened, not what is currently happening.

Using the VMware Infrastructure Client, you can view some of the logs in real-time, but there is only a small amount of logs to choose from.

So how is it done? Read the rest of this entry »

Testing Network throughput between VMware ESX Hosts

web-image-f23fe804058174dd4b4eabfde4bedd8bHave you ever wanted to check your Network throughput between your ESX Hosts? or even between VM’s? Well I needed to do this, and I couldn’t find any straight forward how-to’s.

Having been pointed in the direction of a simple application called IPerf by Simon Gallagher I opted to use the Windows version. I’m not great with Linux, and as this is an open source application, documentation is a little hard to come by. So for me, this post is also to remind me how on IPerf works should i need to use it again.

Allocated Unlimited Memory…Or Have You?

After doing a range of Memory testing and analysis on a group of Vmware Virtual Machines, the subject of the “Unlimited” Memory/CPU tick box was brought up.

When Resource Allocation’s are setup on a VM there is the option of selecting an Unlimited Limit. It seems as though some people misunderstand exactly what that tick box means.

So i will do my best to try and explain exactly “Unlimited” means.
