web site. The challenges are designed for individuals to do on their own to build up their PowerShell scripting skills. A few weeks ago, a challenge was posted to create a network monitoring tool using PowerShell and the Write-Progress cmdlet. I thought I'd share my notes on the challenge and some of the code I came up with.

can make your life better as an IT professional. I have a friend - let's call her Gladys Kravitz. Gladys and I were chatting and she mentioned how tricky it is to pull information out of Windows event logs. If I recall, she was looking at 4625 events in the Security log which represents failed logon attempts.

third-party, but Microsoft signed are safe(r). In this blog post, I will show you how you can scan your system for non-Microsoft signed Windows Services and create a report on those.

mentioned in Part 1, Part 2, and Part 3) to include DHCP scope information, and IIS-based website information.

only on a 'custom' script. Considering how many variables are involved: requirements, environments, the overall experience of the team that will manage that piece of software, and all efforts to develop, test, and support the solution over time.

how to create a multiple fragment body and why it's needed for more complex reports.

Module to display performance metrics.

and/or your team know PowerShell and, perhaps, already have some PowerShell scripts to manage web services, using PowerShell to monitor uptime may be a good option.

in a lot of the communities I frequent but a worry popped up by someone recently; how am I sure that the Azure Application Proxy is always completely functional at my clients? You can monitor the service of course, but that does not mean that the entire connection to Azure is functional.

production. A friend of mine is using my PSexec monitoring script. He just has a couple of issue with that; he's running an application that actively uses psexec to create some elevation. That's quite...

how to literally monitor anything! All you need to get started is our PowerShell MP, plus some APIs and custom discoveries - happy monitoring!

for a while. He told me that he loved having the ability to measure the users experience but he had some clients with in-house applications that would write errors to the system log constantly, or he had other clients with crashing services that could not be prevented.

actually released it on the blog so I figured it's a good way to get back into blogging.

clients don't notice downtime when a failover or load balancing action occurs. It makes everything smooth and fluent for clients and users of our systems. The only problem with this is that sometimes a failover occurs and you don't notice. Great for users, not so great for administrators; if a server crashes in the woods, did it really crash at all? To make sure we always get notified about these situations we use the following script via our RMM system.

and ports being in use. The use case is that users have a Autocad type application installed that launches a server on a specific port; the users also run a remote control application that at times steals the port.

little more difficult . Microsoft allows per-user MFA, Security Defaults, and Conditional Access all to be used concurrently. I've created this monitoring script that returns which users seem to fall out of any Multi-factor authentication scope, and also reports what type of authentication is currently active on the tenant. Using the normal PowerShell methods you can only find if a user has per-user MFA enabled, if a user uses Conditional Access or Security Defaults it shows the per-user MFA state as disabled, which is a little annoying.

or the backup software does not work, they still have an image based backup for those huge emergencies.

needed an easy way to manage virtual desktops over many regions. This deployment actually got me thinking about how monitoring the WVD environment should be done.

small analysis on stuff like disk space can make a huge difference in how you respond to incidents but I rarely see this integrated into RMM systems - Often there are some reports on which you could extrapolate this data manually but that means you'll only do it on demand and it will require your time.

demonstrated during the conference. The presenters showed a method of checking if your O365 domain was being Typosquated. The tool can be found here. The presenters made a Python tool, and I figured to create an alternative in PowerShell.

generally down for everyone else, too. PowerShell can ask a web service to check web site availability for you. Here is a simple wrapper function.

In this article, we will explore how to use PowerShell for troubleshooting, covering event logs, performance counters, services, and processes
