using fio tool in ceph development cluster (vstart.sh)

Hi, I am using the Ceph development cluster through vstart.sh script. I would like to measure/benchmark read and write performance (benchmark ceph at a low level). For that I want to use the fio tool. Can we use fio on the development cluster? AFAIK, we can..... I have seen the fio option in the CMakeLists.txt of the Ceph source code. Thanks in advance. BR
