Subject: [dpdk-dev] [PATCH v6 3/3] ethdev: add common stats for telemetry
Date: Mon, 20 Jul 2020 12:19:07 +0100	[thread overview]
Message-ID: <20200720111907.30717-4-ciara.power@intel.com> (raw)
In-Reply-To: <20200720111907.30717-1-ciara.power@intel.com>

The ethdev library now registers a telemetry command for common ethdev
statistics.

An example usage is shown below:

Connecting to /var/run/dpdk/rte/dpdk_telemetry.v2
{"version": "DPDK 20.08.0-rc1", "pid": 14119, "max_output_len": 16384}
--> /ethdev/stats,0
{"/ethdev/stats": {"ipackets": 0, "opackets": 0, "ibytes": 0, "obytes": \
    0, "imissed": 0, "ierrors": 0, "oerrors": 0, "rx_nombuf": 0, \
    "q_ipackets": [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0], \
    "q_opackets": [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0], \
    "q_ibytes": [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0], \
    "q_obytes": [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0], \
    "q_errors": [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0]}}
