What are the processor performance counters?
Processor performance counters are hardware counters built into a processor to “count” certain events that take place at the CPU level, like the number of cycles and instructions that a program executed, its associated cache misses, accesses to off-chip memory, among several other things. The events that can be tracked with performance counters are usually simple ones, but combined in the right way can provide extremely useful insights of a programs behavior and, therefore, constitute a ...

How to monitor for memory leaks?
The best counter to monitor for Memory Leaks is Private Bytes. If it keeps rising, then you probably have a memory leak on your hands. If you want to isolate the problem between managed and native memory, check the # Bytes in all Heaps counter , which measures the managed memory. If it rises along with Private Bytes, then it’s a managed memory problem. If it stays stable while Private Bytes rises, then it’s a native memory problem.
What does % CPU time mean?
Process | % Processor Time (Total or per process) – Shows CPU usage for the entire machine or a specific process. Can indicate a lot of issues. On hung apps, if the Processor Time maxes out, then the process is stuck on a CPU-bound operation like an endless loop. If the Processor Time is 0, then it might be a deadlock or stuck on an I/O request. Note that this number reaches up to 100 * [number of logical CPUs]. So when you see 100% value, it doesn’t mean the CPU maxed out.
