You need to enable the monitoring PML in order to get access to the pml_monitoring_messages_count MPI_T. For this you need to know what PML you are currently using and add monitoring to the pml MCA variable. As an example if you use ob1 you should add the following to your mpirun command "--mca pml ob1,monitoring".
