Tool to measure memory usage inside the enclave.

[victormassy]

Hey,

I'm looking for a tool to measure the memory used by my application inside the enclave. Do you know anything that could do the job?

Thank you

You can print /proc/<pid>/status and check VmPeak: field, we emulate it inside Gramine.

Do you mean checking the status of the process that calls gramine-sgx ? How can I find the process ID ?

[victormassy]

I've tried something like that gramine-sgx main && cat /proc/$$/status , but I'm not sure if this really check the process inside the enclave.

No, I mean reading this file from inside of Gramine.

Thank you for your answer ! I've conducted some tests. VmPeak for my application is always around 1GB no matter the size of the input file. It seems that the memory allocated to one specific process is decided before execution. Is it true?

I don't know what your application does nor how it's configured, so I can't tell ¯\_(ツ)_/¯ It's your application allocating the memory.
