Network Watcher
Network Watcher is an Azure management tool designed to help DevOps teams monitor, diagnose, and gain insights into network performance. It enables engineers to run remote packet captures and visualize network topology for troubleshooting purposes. The service operates on a pay-as-you-go pricing model, meaning costs accumulate based on usage rather than a fixed subscription fee.
Choose this service when you need to actively diagnose connectivity issues or inspect packet data across your Azure infrastructure. Be aware that there is no free tier available, so every usage incurs direct charges. This lack of a free allowance is a significant limitation for teams testing the tool, as they must budget for all monitoring activities from the start.
