1、查看信息来源

#查看来源
cat /sys/class/thermal/thermal_zone0/type
#查看值
cat /sys/class/thermal/thermal_zone0/temp

2、编辑脚本

sudo vim /opt/snmp_extend.sh 

#!/bin/bash
declare -A SENSOR_MAP
SENSOR_MAP[A0]="0"
SENSOR_MAP[CPU]="1"
SENSOR_MAP[GPU]="2"
SENSOR_MAP[PLL]="3"
SENSOR_MAP[PMIC]="4"
SENSOR_MAP[Thermal]="5"

function PrintUsage() {
  echo "Usage: snmp_extend.sh SENSOR -g OID"
}

if [[ "$2" = "-g" ]]; then
  ZONE=${SENSOR_MAP[$1]}
  if [[ $ZONE ]]; then
    SENSOR_NAME=$(cat /sys/class/thermal/thermal_zone$ZONE/type)
    SENSOR_TEMP=$(cat /sys/class/thermal/thermal_zone$ZONE/temp)
    echo $3
    echo integer
    echo $SENSOR_TEMP
  fi
elif  [[ "$2" = "-n" ]]; then
  exit 0
else
  PrintUsage
fi

3、添加到 /etc/snmp/snmpd.conf中

sudo vim /etc/snmp/snmpd.conf

#增加oid
view   systemonly  included   .1.3.6.1.4.1.1989

#pass 动态增加节点
 pass .1.3.6.1.4.1.1989.10.1 /opt/snmp_extend.sh A0
 pass .1.3.6.1.4.1.1989.10.2 /opt/snmp_extend.sh CPU
 pass .1.3.6.1.4.1.1989.10.3 /opt/snmp_extend.sh GPU
 pass .1.3.6.1.4.1.1989.10.4 /opt/snmp_extend.sh PLL
 pass .1.3.6.1.4.1.1989.10.5 /opt/snmp_extend.sh PMIC
 pass .1.3.6.1.4.1.1989.10.6 /opt/snmp_extend.sh Thermal

4、重启snmp服务器并查看

$ systemctl restart snmpd
$ snmpget -v2c -c public 127.0.0.1 .1.3.6.1.4.1.1989.10.1
iso.3.6.1.4.1.1989.10.1 = INTEGER: 39500
