Visual ESXiTop

Not everyone likes digging into the VI/Command line, or it’s not always easy to get access, or the right person to do it…Then it’s even more awkward to get that information out to somebody…

 

Not anymore – thanks to the magic and hard work put into Flings!

Troubleshooting non responsive VMs

Sorry for the gap in posting…well…anything… New role has kept me very busy!

Most of us will have our own little tips and tricks on troubleshooting, but recently I had a customer who had a machine hanging, that looked suspiciously like VMware Tools was causing an issue, but they had no idea how to troubleshoot. I’d suggested various options, including simply getting the logs, checking ESXi services and so on and it wasn’t anything they’d had to do before, so I really needed something quick and fully features to suggest to them. There’s a great VMware KB which uses the process of:

Validate the scope – find out the scope of the problem and accurately define what the symptoms are (no point in just having someone screaming “It’s crashing, IT’S CRASHING!”

Identify the cause – so many possibilities! Storage, services crashing, resource contention, a task on the VM…

Action Plan – Take action to remediate the issue – once the cause has been established, focus on what is causing the issue and define a plan to resolve it.

Flings of the day!

OK, if you aren’t au fait with Vmware Flings, go here:

VMware Flings

They’re basically community built apps/tools developed and provided for free to enhance many of the features within vmware products.

Some of them you’ll never use and some of them will become invaluable.

Today, I’d like to share with you, a few of my favourites.

ESX Embedded host client

This is something that is really, really handy. I’ve been in situations where networking has been spotty and even physical connections via KVM haven’t been feasible, either due to being at the forefront of standing up new hardware, stood in a freezing cold DC in the middle of the night, secretly taking a bite out of a protein bar and a swig from the tesco finest diet energy drink before one of the engineers sees the Food/Drink alarm going off and comes to tackle you to the ground… Or just because everything has gone wappy and you can’t connect.

This installs something akin to the web based vSphere client, directly on the host, meaning no reliance on vcentre, or when the vSphere client is having issues, or your laptop doesn’t let you change the VLAN on your NIC etc – I just found it was another backup in case of emergency (and we all need those!)

My other favourite for Horizon View is…

Horizon Tool Box

It does Auditing…It does Power Policy…But most importantly…REMOTE SUPPORT AND CONSOLE ACCESS! In all fairness, the ability to power on machines at certain times etc is really useful… The remote access leverages MS remote support as well as allowing console access to shadow.

I’ve been involved with many View deployments where one of the first concerns of IT staff is “How do we remote on to users desktops?” – and this answers that question. It’s quick and easy. Just remember to actually read the instructions (I know, I know, that can be a difficult to motivate yourself to do!). One of the main problems comes when people don’t enable RDP on the desktops – just an FYI there 😉

View Client Resizer

I use a 2k monitor with a 4k laptop screen and as you can imagine, apart from the usual resolution/display scaling issues, it can be a right pain when working on multiple view sessions – especially when I forget the set the res to not full screen across my monitors, leading to a black screen and a broken connection – this little exe means you can manage all the sessions you have open and is a handy little tool!

 

Add multiple ESXi Hosts to vCenter (PowerCLI)

So if you’ve read some of my previous posts, you probably figured out that I’ve built a fair few environments from scratch and hate having to rinse and repeat manually. For my last infrastructure project I have some various scripts and tools to sort that out!

The following link lets you add ESXi Hosts to vCenter via PowerCLI, by Hostname range, IP Range, or text file/CSV. I used textfile and name using this method and it worked perfectly.

This ties in with DNS entry creation as well as it means you can quickly and easily add all your hosts and create the DNS entries for them as well.
