PowerShell+ 2019 - Finding Performance Bottlenecks with PowerShell by Mike F. Robbins

Have you ever walked into the office one morning only to discover major performance problems after leaving the previous day with everything operating normally? How do you begin to diagnose this type of performance problem? While PowerShell may not be your first thought, it can offer a quick way to identify where the problems reside. The Get-Counter cmdlet, which is used to query performance counters on Windows based systems, isn't very intuitive to say the least and its results aren’t what I would call a great object-oriented design. During this session, you’ll learn how to find performance counters and what the top 10 most important performance counters are along with their recommended values. You’ll learn how to query performance counters, create a reusable tool to query the top 10 performance counters, and automate the validation of those performance counters with Pester. Finally, you’ll learn how to create advanced validation tests for those performance counters. PowerShell Summit videos are recorded on a "best effort" basis. We use a room mic to capture as much room audio as possible, with an emphasis on capturing the speaker. Our recordings are made in a way that minimizes overhead for our speakers and interruptions to our live audience. These recordings are meant to preserve the presentations' information for posterity, and are not intended to be a substitute for attending the Summit in person. These recordings are not intended as professional video training products. We hope you find these videos useful - the equipment used to record these was purchased using generous donations from members of the PowerShell community.
