[dpdk-dev] [PATCH v9 08/12] telemetry: format json response when sending stats

Harry van Haaren harry.van.haaren at intel.com
Sat Oct 27 01:59:29 CEST 2018


From: Ciara Power <ciara.power at intel.com>

This patch adds functionality to create a JSON message in
order to send it to a client socket.

When stats are requested by a client, they are retrieved from
the metrics library and encoded in JSON format.
