Search Power Cuts In The UK Using PowerShell!


So recently I’ve met this problem that we lost power in one of our offices in the UK, however we didn’t know the reason – might have been UPS malfunction, some bypass troubles, etc. Finally we identified there was a power cut by calling local users.

To make similar problem identification more swift and robust (basically to include that in our IT infrastructure monitoring solution) I’m preparing (still under development ^^) a module that might help in identification if there is a power cut for certain post code.

[WTF?] VMware ESXi 6.5 – “Cannot complete login due to an incorrect user name or password”

Hi Chappies,

Just few momenst ago I had a really dodgy issue with loggin to newly installed ESXi6.5.

I deployed it few days ago, after instalation I logged in by copying password to the VMware console from KeePass application – logged in to that box, configured SSH connectivity and done some additinal configuration. After that connected via PuTTY as well.

Today my colleague just came from holidays and tried to log in – he got following error:


I thought that he we have some sort of different KeePass DB versions – but no.


I was not able to log in either! So I tried not to copy, but instead to type the password in the form field – same failure.

So, I went to the server room, and tried to log in directly to ESXi using KVM – and guess what? 🙂 All went well! So I came back to my desk, tried to log in by copy/paste credentials from KeePass – instant success!

The question that still remains in my head – and I hope VMware or someone from community might answer one day – is:


Anyone able to help in resolving the “(ES)X Files” riddle?

PowerShell script for Exchange mailbox item (email, meeting, contacts, etc.) removal.

You might have a situation when someone – it might have even been you – send or receive an email that shouldn’t be sent or received.

It might have been a SPAM sent to your organization or an email that supposed to be send to your colleague but was send to a bunch of other people and had naked ladies in the attachment.

After sending such email reaction chain is as follows:

First you noticed that you have might clicked “Send” button, maybe you clicked CTRL + Enter combination, but you still not sure…

PowerShell script to auto approve WSUS updates for pilot and standard groups.

Recently there has been a need for me to create script that will cover auto approval work for WSUS.

So the idea was tu approve certain patches to pilot group, and after 2 weeks apply these on standard target group and do another pilot group approval for latest time span.

Important! WSUS target groups need to have “Standard” and “Pilot” in their names.

Lines of code that are worth mentioning:

## 64th LINE
## Specify time span between pilot and standard approvals, below is 14 days
$Next_Approval_Date_Raw = (Get-Date).AddDays(14)
## 106 - 108 LINE
## Specify the report file name and path
$CSVFileName = $range+"UpdateTimes.csv"
$CSVPath = 'c:\'
$CSVFile = "$CSVPath$CSVFileName"

So after specifying what period we like we just need to specify the file name and path and we are ready to go!

If we would like to show it on diagram it would look like:


Of course we may add many things to it’s functionality and this is just the very early version of the script. Worth adding might be – and probably will be added in future – a list of updates that were approved to particular target group – it s already there in “verbose” mode, adding possibility to choose the target groups by name other than “Server” or “Workstation”.

SQL long running jobs alert script in PowerShell

databaseHi folks!

Recently there was in a need of monitoring jobs on SQL – if they finish in timely manner. So I was looking for ready solution, found two: and however both are SQL jobs that monitor SQL jobs. I feel quite good in TSQL…


…however that solution didn’t suit me from few reasons:

  1. I wanted to do monitoring of SQL jobs as an independent from SQL jobs failure.
  2. I might need to modify add something in the future and it would be easier for me in PowerShell
  3. Above solutions were giving alerts when a job run time was above average – not over certain time – an I needed that. Didn’t know how to do it in SQL.

So the decision was made:


To make it running in your environment just modify these lines:

## 10th-12th LINE
$fromemail = ''
$mailserver = ''
$toemail = ''
## 21st LINE
## 71st LINE
if ($Date_Diff.TotalMinutes -gt 5){

So in this example a script will send an email in HTLM:

If a job runs over 5 minutes.

So there you go 🙂 it is easy, no parameters and really dirty. I like it 🙂

HP MSA – PowerShell script to check if disk drives firmware revision is up to date.

Recently I came across updating firmware on some HP MSA appliances.

As there were many different disk drives models on those, I started to wonder – how would I know if any new firmware has been released?

I didn’t want to search firmware for 10 different disk drives models every quarter neither. Firstly because I would forget, secondly – time consuming.

It was no brainer that I needed some automation for that stuff.

I found a HP website providing disk drives firmwares:

Unfortunately I was not able to find any of these for controller firmwares or enclosures.

Fortunately for controllers and enclosures checkout is easy, also usually we get information in controller firmware documentation which firmware revision is recommended for enclosure.

Script need to have current MSA firmware information in a JSON file – as for now this process is not automated and information need to be put manually in the JSON file.

What script does is it is going though mentioned website creating hash array of objects basing on very hideous HTML parsing (yup, I know it is ugly AF but well… works ^^).

After it got all that shit from the website, it runs array one by one checking looking for particular object by disk model, and comparing it’s current firmware revision from JSON to what it found on the website.

And here is the thing, there are 3 statuses:

Green – disk has the newest firmware

Light Green – disk most probably has the newest firmware.

Red – disk has an old firmware

You might ask – why we need Light Green. Well, sometimes one disk drive model is visible twice as different model, like below:



So these two are the same model, but have different firmware.

If script finds such situation, it checks if your firmware revision is among these found on the website – it also lists what firmware revisions have been found for that particular drive model. If your firmware revision is there – drive is reported as light green.

Output should look like:


As you probably noticed for controllers there is just list to verify firmware version – I didn’t find any good source to script can run trough it checking if it is up to date, so as a workaround there is a fixed link in JSON file – it is always better just to click it and check current version than to search every quesrter for the correct link.

Script has 4 simple switches:

-File – switch parameter, if ran with that it will generate HTML file

-FilePath – default path is “.\”, so if you want to put HTML file somewhere else – this is the right place

-Email – switch parameter, if ran with that it will generate an email.

-Verbose – you got additional information about what actions have been done

Hope it will be helpful for some of you guys.
