Is there a tool on mac os for monitoring hardware performance counters?
What are hardware performance counters?
If you mean is there a counter to keep track of battery cycles then yes. If you mean is there a counter to count the number of times your RAM was used past 50% then no. If you mean is there a utility to report real time memory use then yes.
Hardware performance counters are registers on every modern CPU that count interesting events like L1, l2 and L3 cache misses, retired instructions, branch miss-predictions and literally hundreds of other things. A good paper to read to get a feeling for the value of such counters is
https://oaklandsok.github.io/papers/das2019.pdf
By the way, the last 2 columns of the top command with the following flags provide the values of two of the most important counters -- retired instructions and cpu cycles
top -d -i 5 -n 25 -s 5 -u -stats pid,command,cpu,time,csw,threads,mem,pstate,instrs,cycles -e
But there is so much more that would be nice to get. Linux, Solaris AIX, among others all have tools to access performance counters. So my question is: does Apple, or some third party have such a tool for Mac machines?
Someone may be able to answer your question now that you've explained what you mean.
