[jacker123test]

Hello, please help to answer two questions about perf related, thank you

1. Which grafana dashboard id is used by perf export？
2. How to display perf hardware events, such as cache-misses events

my environment：

1. cat /proc/sys/kernel/perf_event_paranoid
   0
2. uname -a
   Linux ubuntu 4.15.18 #2 SMP Thu Feb 24 14:27:34 HKT 2022 aarch64 aarch64 aarch64 GNU/Linux

5.mount | grep -E '(debugfs|tracefs)
debugfs on /sys/kernel/debug type debugfs (rw,relatime)
tracefs on /sys/kernel/debug/tracing type tracefs (rw,relatime)

6. cat /boot/config-$(uname -r) | grep -iE '(perf|debugfs)

Which grafana dashboard id is used by perf export？

There currently isn't one published to grafana, but feel free to do so.

How to display perf hardware events, such as cache-misses events

For this you would want to use node_exporter.
