BMC Restful API

Read data from hardware sensors using libsensors. Get Json fromat data by Restful API.

Usage

Server

1. cd ${HOME}/go/bin
2. ./go-server

Client

• http://localhost:8093/v1/
  The brower shows "BMC Restful API v1!"

• http://localhost:8093/openconfig-platform:components/component=hwmon
  The brower shows the results of all howmon devices

• http://localhost:8093/openconfig-platform:components/component={hwmon_id}
  The brower shows the results of one howmon device

APIs

• hwmon_connector_t hwmon_all_get(void)
• hwmon_connector_t hwmon_get(const char* hwmon_id)

Libraries

1. Libsensors

• Use lm-sensors lib to parsing /sys/class/hwmon files. libsensors privoide the following APIs to get hwmon strings.

  • int sysfs_read_chips(void)
  • int sysfs_read_one_chip(const char *hwmon_path)
