prometheus alert rules文件格式化

1.下载go(version>1.9,否则promtool工具不好使)

https://golang.org/doc/install?download=go1.10.2.linux-amd64.tar.gz

tar -C /usr/local -xzf go1.10.2.linux-amd64.tar.gz

export PATH=$PATH:/usr/local/go/bin

2.yuml install -y git

3.下载安装promtool

go get github.com/prometheus/prometheus/cmd/promtool

设置环境变量：

 export PATH=$PATH:/root/go/bin

4.校验rules文件

promtool check rules test.rules

5.更新rules文件为yaml文件

promtool update rules test.rules

结果生成 test.rules.yml文件
