webhook发送的body中未包含value信息

[lefreet]

问题

• 采用自定义服务转发webhook的消息格式，发送过来的请求中无相关实时值.Value，希望能够带上，用于告知管理员当前实时数据

@junotx prometheus alert rule 计算的只是一个阈值是否超限，结果类似是否告警这种二元信息，可能带上 value 的信息吗？

@benjaminhuo 看了模板的文档， webhook 是用template 特殊序列化的（没找到具体实现），template本身有支持.Value，应该可以； 本身用grafana的另一套监控系统是支持这个机制的，应该是常规操作
