pcm-memory failed on i9-9900

[jefby]

Hi I want to monitor memory bandwidth with command pcm-memory, but it failed on my platform.
Linux ubuntu18.04 kernel 4.15, and error log

 Intel(r) Performance Counter Monitor: Memory Bandwidth Monitoring Utility ($Format:%ci ID=%h$)

 This utility measures memory bandwidth per channel or per DIMM rank in real-time

For processor-level memory bandwidth statistics please use 'pcm' utility
Cleaning up
 Closed perf event handles
 Zeroed uncore PMU registers

How to fix this problem? Thanks very much
