查看“钉钉机器人zabbix报警”的源代码

=安装Python3、相关包以及创建钉钉发送消息日志文件=
<pre>
#这个看你自己的情况
# 安装python3，脚本是基于Python3写的
yum install -y python3

# 安装pip，pip是python的包管理器
# 下载pip安装脚本
curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
# 运行安装脚本
sudo python3 get-pip.py
# 安装puthon包
pip3 install configparser
pip3 install requests
# 创建钉钉发送日志文件路径
touch /var/log/zabbix/zabbix_ding.log
chown zabbix.zabbix /var/log/zabbix/zabbix_ding.log
</pre>

=首先在钉钉群聊里添加一个自定义的机器人=
并复制webhook的内容 如下面 创建新建群手加入 机器人就可得到

https://oapi.dingtalk.com/robot/send?access_token=37e23308d1b84eb4ac34566e03c4c4e74b7eedecbcc002exxxxxxxxxxxxxxx
 还有一个 安全设置 -- 加签 时得到

=创建脚本=
在zabbix服务端的alertscripts目录下新建一个python脚本
==py3 Oct 2021==
<pre>

#pre config


# 查看zabbix的脚本默认路径，请注意使用您自己的zabbix_server.conf 类似这个样子
cat /etc/zabbix/zabbix_server.conf |grep AlertScriptsPath
### Option: AlertScriptsPath
# AlertScriptsPath=${datadir}/zabbix/alertscripts
AlertScriptsPath=/usr/lib/zabbix/alertscripts


 添加配置文件zabbix_ding.conf，并将文件上传至/etc/zabbix/下(进入容器) 或者放在母机指定的mount的目录中 例如下面的py3 脚本 ding.py

[config]
# 日志文件
log_path=/var/log/zabbix/zabbix_ding.log
#钉钉机器人 webhook 值
webhook=https://oapi.dingtalk.com/robot/send?access_token=b3e6fa0f410e7ced04c81680f036xxxx
# 安全设置 -- 加签 时得到
secret=SEC64d20b4e9d2e2677f7aa01d2a7c2f9xxxx

trouble 

readonly 是docker-compose 配置 直接去母机  
zbx_env/usr/lib/zabbix/alertscripts



alertscripts]# chmod +x ding.py

Media type test failed.

    Cannot execute command "/usr/lib/zabbix/alertscripts/ding.py": [2] No such file or directory



有时重启不成功

关掉机器人中的 自定义关键词
