In all my investigations, a problematic migration from Customer A may be happening at the same time as Customer B, C, D…. PerfView is probably the number 1 tool I use when investigating application issues. It uses Event Trace for Windows (ETW) technology, so the trace can be visualized by other tools. PerfView can also collect information like network packets, File I/O and Registry access, among others. PerfView is definitely not for the average user (this comment is intended as motivation, not discouragement!) it’s very powerful, and having a solid understanding of how Garbage Collector works is a must in order to comprehend all the information PerfView provides. PerfView is a very light profiler for production environments to help investigate issues related to memory or CPU for. That means you can view the same trace in different ways, depending on the tool you’ve selected to visualize the trace! Your selection should be based on what you need to do. Today we’ll discuss three more valuable tools:Ī little-known fact: these three tools are related. At our scale when problems happen, they can be very difficult to track that’s why we need great tools.
