PowerShell+ 2019 - Moving Up the Monitoring Stack by Steven Murawski
0Let's be honest - cloud migration can be scary. There's a lot of potential change that can happen in how we run our applications. What does the IT operations professional bring to the table when we start taking VMs out of the picture?
One answer to that is in how we evolve our monitoring. For ages, we have focused our monitoring infrastructure watching things like CPU utilization and number of page faults in RAM access. We stress over disk queue lengths and network response times. Once we move out of Infrastructure as a Service (IaaS), our visibility into these indicators change. We need to move up the stack and find out what application metrics we can use to provide similar insight (or even better) into the state of our application environments. This provides one path for us to take our operational experience and apply it to things like Platform as a Service (PaaS), Functions as a Service (FaaS), or hosted container environments.
We will take a sample application running on a virtual machine and a few related perf counters, convert them into application metrics (no development experience required!), and see how we can maintain our insight into the performance of our applications. Bring your experience and intuition and help shape the move up the stack!
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.
