perf is a vital performance measurement tool

We've encountered an issue with the perf command not working on our current AWS instance. When running the command sudo perf stat -e instructions:u echo "soma", it returns <not supported> instructions, which is unexpected.

Hello.

Could you please share the type of OS you are using on EC2?
Also, if you run the command below, will "instructions" be output to the list?
If it is not output, it may not be supported.
