通过Zabbix API在告警邮件中插入趋势图

发表于 2018-03-25 更新于 2019-03-04 分类于 zabbix 阅读次数：

告警邮件中嵌入趋势图是非常人性化的设计，只有有温度的告警邮件才会嵌入趋势图。。。

以下内容基于zabbix 3.0.2 测试有效，想必其它版本应该也问题不大。

话不多说，直接上代码：

邮件告警脚本

cat mailAlarm.sh

    return 0

	# 如果没有传入STIME参数，STIME的值为当前时间减去PERIOD
	[ "$STIME" == "" ] && STIME=`date -d "now -${PERIOD} second" +%Y%m%d%H%M%S`
}

# 关键步骤，获取cookie并写入文件
function getCookie()
