Memory bandwidth without uncore counters

[Anatoly_S_]

Hello!

I'm trying to get the RAM and cache bandwidth metrics. It is seem possible to benchmark the system capacity, using lmbench for example, but I wonder how to do it for existing process (i.e. utilization)? 

I see, that I can use uncore counters with `perf` utility, but seems like there is no uncore support on my processor:

model           : 60
model name      : Intel(R) Xeon(R) CPU E3-1230 v3 @ 3.30GHz
stepping        : 3
microcode       : 0x1a

# ls /sys/bus/event_source/devices/
breakpoint  cpu  software  tracepoint

How can I track for the memory bandwidth metrics for some PID, more or less accurately? 

Thanks in advance!

There are some memory bandwidth counters in the Xeon E3-1230 v3, but they are not easy to use....

Intel Performance Counter Monitor contains a sample implementation for reading these counters. However, they don't allow you to distinguish between processes. My recommendation is therefore that you do the measurement on an otherwise idle system.
