Running vRops on Ravello

Posted 1 CommentPosted in Ravello, vRops

I recently did a blog post on how to get vRops running in vCloud Air, see here. At the same time I have been using Ravello Systems cloud platform (free for vExperts) to run a vSphere 6 environment. Have been trying to run vRops before on Ravello before, but ran into an error message and due to the limited time I have to play/learn I skipped finding the cause. Luckily I found some time and revisit this error message. The error comes when ever I try to upload the OVF(an extracted OVA).  The error message says: An error occurred: You attempted […]

How to change VMDK geometry

Posted Leave a commentPosted in Ravello, Script, vRops

I recently ran into an issue were I needed to change the geometry of some VMDK files – I will do a seperate blog post on where and why later. For now I will just focus on how to change VMDK geometry. A VMDK is just a file with some descriptional data and the actually binary data of the VMDK. Think of it as a virtual harddisk. It adheres to the same physical characteristics and there for the physical characteristics are also part of a VMDK file. Normally you won’t need to change the geometry of a VMDK – I this case […]

Running vRops in vCloud Air

Posted 1 CommentPosted in vCloud Air, vRops

Lately I have been using quite some time on a lab environment which I had running in vCloud Air – There were two reasons for using vCloud Air, first one was to test it and see how it was to run something like this on the platform – I must say I was pleasantly surprised, compared to other cloud services vCloud Air seemed a lot faster, just like running a VM in an internal datacenter. The second reason, the one that got me on this track to test vCloud Air was a promotion to test vCloud Air and get some […]

My vRops VMUG Presentation

Posted Leave a commentPosted in vRops

Hi all It has been a busy two weeks since I started working for Proact and did my presentation titled “vRops 6 Operational Deep Dive” at the Nordic UserCon in Copenhagen. Like I said it has been some busy days – For that reason I haven’t found the time to put up the presentation. I will now correct that. I know that this isn’t the same as having been there, but some might do a quick recap and others might find some new questions to ask. I did some demoing, some on a local environment on my laptop and the rest […]

Troubleshooting with vRops part 4: Standard Deviation

Posted 1 CommentPosted in VMware, vRops

In the last blog post I showed you what Object level metrics are and how they could be used, to fast get an idea to of how a VM is behaving. In this one I’m going to focus on what metrics can be used to get a better understanding of how a VM is behaving. One of the hardest parts of performance troubleshooting is to know when you have good performance and when you have bad. Is 100% CPU usage for 2 hours a week bad ? Is 10 ms storage latency bad ? Maybe not. What if the blocksize […]

Troubleshooting with vRops part 3: Object Level Metric

Posted 3 CommentsPosted in VMware, vRops

In this part I am going to show you how to use object level metrics, to fast and easily assess if for example a VM is having problems. This is something that would give you a quick indication of this object is having problems that need to be address. This should be looked at before diving into the raw metrics, as this will help you and can guide you in the right direction.

Troubleshooting with vRops part 2: Summary and Symptoms

Posted 3 CommentsPosted in VMware, vRops

In the first part of this series on vRops, I talked about vRops capabilities compared to the vRops edtion. In this part I will start to dig into how you should start looking at a problem the vRops way. I my self have fallen victim to, all too quickly jumping over to the “all metrics” tab, and start throwing graph up on screen to see if I can find the cause of the issue. The problem with that method is that it is highly inefficient and like looking for a needle in a haystack, it can take quite some time and […]

I’m speaking at Nordic UserCon 2015

Posted Leave a commentPosted in Uncategorized

Nordic UserCon 2015 is coming up fast, less then a month now. If you haven’t already seen the agenda, have a look here at my previous blog post. I’m holding a session about vRops. The title is vRops Operational Deep Dive – So I’m not going to talk about xDB, vPostgres or Cassandra, as I don’t wanna do a techinal deep dive. In my opinion, vRops is a product where you shoudn’t really care about how it works. Just know it works, how to deploy it and how to use it. This is after all the operational side of things I’m […]
