Options

To start profiling NVMe/TCP, you need to configure the profiling specifications in the ntprof_config.ini file. The configuration file is divided into several sections, each of which contains a set of options. The following table lists the available options and their default values.

IO_SIZE	string	Fixed size of IO to collect	"all"
[Execution]		Configuration for execution constraints or limits
NETWORK_BANDWIDTH_LIMIT	string	Network bandwidth limit in MB/s	"INF" (no limit)
NVME_DRIVE_BANDWIDTH_LIMIT	string	NVMe drive bandwidth limit in MB/s	"INF" (no limit)
