This commit adds code in GO language to expose Physical Function
interface device info and statistics (metrics) of a node using
REST API service.
NIC Statistics provided by Netlink.
Following APIs are implemented:
/metrics -- all statistics in OpenMetrics format
/metrics/device/{DeviceName} -- particular device statistics in
OpenMetrics format
/metrics/pci-addr/{PciAddr} -- particular pci-address statistics in
OpenMetrics format
/json/metrics -- all metrics in json format
/json/metrics/device/{DeviceName} -- particular device statistics in
json format
/json/metrics/pci-addr/{PciAddr} -- particular pci-address statistics
in json format
Test Plan:
PASS: GO linting
PASS: Unit test
PASS: Api test.
PASS: Docker image build process defined
here [1]
PASS: Created container image of this app, pushed to local registry
and deployed on AIO-SX lab using sample deployment file.
Then tested the APIs and validated the results.
