sgxtop

This is Fortanix's SGX monitoring application, built to interoperate with our SGX driver extensions that export SGX usage information.

It'll list the enclave count, overall enclave memory use, paging rates, and the enclaves in use, along with their memory usage and information about the owning process.

Usage

$ sgxstat
$ sgxtop

Build

Build dependencies: autoconf automake m4

Set up the makefile, etc., from the autotools:

$ ./maintainer.sh
$ ./configure
$ make
$ sudo make install

Driver Installation

In order to use this, you'll need to rebuild your isgx driver using our monitoring extensions. You'll then need to stop the Intel aesm daemon which is probably running at least one or two enclaves on your system, then remove the current driver, install the new one, and restart the aesm daemon.

Here are the instructions to make it work on Ubuntu 16.04:

$ git clone https://github.com/fortanix/linux-sgx-driver
$ cd linux-sgx-driver
$ make
$ sudo make install
$ sudo systemctl stop aesmd
$ sudo rmmod isgx
$ sudo insmod isgx.ko
$ sudo systemctl start aesmd
