Performance Monitor
perfmon.msc (or perfmon /res for a quick Resource Monitor-style overview)The graphical console for tracking detailed performance counters (CPU, memory, disk, network) over time, and building custom data collector sets for longer-term monitoring.
// EXAMPLE
Adding the "% Processor Time" and "Available MBytes" counters to a live graph to watch for a memory leak over an hour.
// GOTCHA
Perfmon's default view only shows a couple of counters — its real value (long-running Data Collector Sets that log to a file for later review) requires deliberately setting that up, not just opening the tool.
