One thing that I absolutely love about vRealize Network Insight (vRNI) is that the entire database is open by default and that the search bar is powered by Elastic Search. That means that you can type in pretty advanced search queries and basically query everything that vRNI collects. The query itself is written in natural language, so you don’t have to be an expert to use it. You can get really creative as well, getting output you would have a hard time seeing without using the search. To give you some examples, below you can find my cheatsheet with searches … Read more
I use CrashPlan Home for all my off-site backups of my client devices. It’s a pretty neat and usable backup client which works on Mac OS, Linux and Windows. From the client you can restore individual files and it runs as a service for continuous backups. It’s a set and forget application, which is nice.
Bye Bye CrashPlan for Home
Recently, Code42 announced they’d be shutting down CrashPlan for Home to focus on their business customers. Meaning every consumer has to transfer their backups to another solution. I had the family plan, which allows you to backup multiple computers (I … Read more
Disclaimer: this is not something for production environments (at least, I hope for your sake, GSS should be able to fix it), but more for test or homelab environments.
Say your vCenter is broken. And I mean really really broken to the point where you can’t get the services to run anymore and you either go through a VMware GSS case and hope they can fix it. I’m good at breaking things and somehow (don’t ask) got to a point where I had broken the SSO and Inventory services and couldn’t get them back up.
I’m not a fan … Read more
VMworld Europe is next week! This is always the highlight of my year, mostly for 2 reasons: 1) all kinds of awesome new virtualization technology is either announced or released, and reason 2) my favorite; the best minds of the virtualization community gather and share thoughts, learning from each other. In the last 7 years I’ve attended VMworld, there’s a few things I picked up and I wanted to share.
There’s a LOT to do
If you wanted, you could fill up about 6 months full time with all the content that’s available on VMworld. The tricky part is that … Read more
Sorry, you actually can’t configure two Netflow targets in vSphere. 😉
HOWEVER! There’s a way around this limitation. Currently, the VDS only supports one Netflow target IP address to send NetFlow to. This limitation can cause some issues when you want to employ multiple Netflow collectors, for instance an existing Network Management System (NMS) and do a vRealize Network Insight Assessment.
What is Netflow?
I’m not going to explain Netflow in depth, but just to set the stage here’s a small summary. Netflow is a protocol that allows you to collect information about what traffic flows are going through … Read more
Certain service appliances cannot be edited manually inside vCenter. For instance, VMware NSX Edge appliances are an example of such service appliances. These VMs are managed by the NSX Manager and you shouldn’t change their configuration manually. Normally. 😉
But sometimes you need to edit those VMs. There are not many reasons why you would want to do this (as it’s heavily unsupported), but one reason might be to free up resources in your home lab (which is exactly why I wanted to do this). For instance, NSX Edge appliances come with a CPU & memory reservation placed on … Read more
I don’t post a lot from my other life, the programming personality, most of my posts come from my adventures in virtualization. I have a bit more fun writing about virtualization than I do writing about programming, plus the number of coding blogs out there is enormous. But I’ve been troubleshooting an extremely hard to pin down issue with one of my applications (WhatPulse), where there would be a latency spike every 10 seconds (or less), only when primarily connected on wifi on Mac OS 10.12 (lower versions don’t seem affected). I’ve been pulling my hair on this … Read more
