The script is interactive and will allow the user to\nregister, request statistics, and unregister.\n\nTo run the script, an argument for the client file path must\nbe passed in: \"python telemetry_client.py <file_path>\".\n\nThis script is useful to see how the Telemetry API for DPDK\nis used, and how to make the initial connection.\n\nSigned-off-by: Ciara Power <ciara.power@intel.com>\nSigned-off-by: Brian Archbold <brian.archbold@intel.com>\nSigned-off-by: Kevin Laatz <kevin.laatz@intel.com>\nAcked-by: Harry van Haaren <harry.van.haaren@intel.com>\n\n---\n\nv10:\n -
