Subject: [dpdk-dev] [PATCH v3 2/2] ethdev: add common stats for telemetry
Date: Thu, 2 Jul 2020 11:19:53 +0100 [thread overview]
Message-ID: <20200702101953.6129-3-ciara.power@intel.com> (raw)
In-Reply-To: <20200702101953.6129-1-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-rc0", "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]}}
