If you just need aggregate stats at the end of the simulation run, such as number of dcache.ReadReq_hits, M5 already does this. When the simulation finishes, it dumps the file: m5stats.txt to your current working directory with everything added up for you.
Dumping stats every cycle can easily lead to multi gigabyte files that will be very hard to work with and store.

Hi, Lisa I only need few stats to analyze the runtime characteristics of an application. For example the number of dcache.ReadReq_hits, icache.ReadReq_hits, etc. I added these codes "Stats::StatEvent(true,false);" in function simulate(Tick num_cycles) located simulate.cc. But I didn't get the result I wanted. Could you tell me what is the correct way to get thest stats? Thank you very much!

I've looked up the code. Maybe I can add some codes in function simulate(Tick num_cycles) located simulate.cc. Fox example, add a StatEvent like "Stats::StatEvent(true,false);" in this function? But I'm not sure how to do it correctly. I'm using m5sim 2.0b5 in SE model. What is the correct way to get this information? Thanks!
