Bosun 具有可选图形的通用模板
示例
通常，在首次创建新警报时使用通用模板会更快，而仅在需要显示更多信息时才专门化模板。下面的模板将显示带有数字值，自定义格式和描述字符串的主题，然后显示具有最多两个图形的主体。如果未指定图形变量，它将列出警报中使用的计算。通用模板还使用警报的名称来生成主题（用空格替换点），并在使用变量防止错误之前检查变量是否存在。

}它将产生一个主题，例如“警告：人偶上次运行：自上次在co-lb04上运行以来已有62分钟”，并包括该主机的last_run和禁用的图表。如果要为查询绘制所有结果的图形，而不仅仅是匹配的标记集，可以使用$generic_graph_all和$generic_graph_all2作为变量名。
