一、参考
参考另一篇博文配置Zabbix-Agent2代理程序
Zabbix5系列-监控Linux主机 (四)
二、安装传感器工具
# 安装lm-sensors yum install lm_sensors # debian等系统使用apt安装 #apt install lm-sensors # 扫描传感器 下一步是扫描所有安全传感器 或根据实际情况控制扫描 sensors-detect # 检查传感器的温度 sensors -u 
三、编写自动发现脚本
# 安装python3 yum install python3 # 创建脚本文件 vi /etc/zabbix/sensors.discovery.py sensors.discovery.py脚本内容：
#!/usr/bin/env python3 # coding:utf8 import os import json def handle35(strdata): temp = json.loads(strdata) data = [] for i in temp: for j in temp[i]: for v in temp[i][j]: if v.find('input')>-1: data.append( {
'{#INDEX}': len(data) 1, '{#DEVICE}': i, '{#SENSOR}': v.replace('_input',''), '{#SITE}': j } ) r = {
'data': data} print(json.dumps(r)) def/span> handle34(strdata): data = [] sensors = strdata.split('\n\n') for i in sensors: line = i.split('\n') if len(line) > 2: site = None for j in range(len(line)): if j == 0: continue elif j == 1 and line[j].find('Adapter') == 0: continue elif line[j][:2] != ' ': site = line[j][:-1] elif line[j][:2] == ' ': if line[j].find('_input') > -1: data.append( {
'{#INDEX}': len(data) + 1, '{#DEVICE}': line[0], '{#SENSOR}': line[j][2:line[j].find('_input')], '{#SITE}': site } ) site = None r = {
'data': data} print(json.dumps(r)) try: version = os.popen("sensors -v").read() if version.find('version') > -1: if version.find('3.5') > -1 or version.find('3.6') > -1: temp = os.popen("sensors -u -j").read() handle35(temp) else: temp = os.popen("sensors -u").read() handle34(temp) else: print('Error') except: print('Error') # 修改脚本所有者
chown -R zabbix /etc/zabbix/sensors.discovery.py
# 赋予脚本执行权
chmod +x /etc/zabbix/sensors.discovery.py
# 测试执行脚本
/etc/zabbix/sensors.discovery.py
成功读取到传感器信息：
四、 添加自定义参数
# zabbix-agent2配置文件插入自定义参数
echo "UserParameter=sensors.discovery,/etc/zabbix/sensors.discovery.py">>/etc/zabbix/zabbix_agent2.conf
# 重启zabbix-agent2服务
systemctl restart zabbix-agent2
五、 导入模板
保存模板文件为Linux_sensors_by_Zabbix_agent.yaml
模板内容：
