-1</p><p>avg()控制如何将每个系列的值减少到可以与阈值进行比较的值。单击该函数可将其更改为另一个聚合函数。 query(A, 15m, now)，表示从A选项卡执行查询，后两个参数定义时间范围15m，now 表示从15分钟前到现在。 IS ABOVE -1 定义阈值的类型和阈值。IS ABOVE表示在-1之上，可以单击IS ABOVE更改阈值类型。</p><p>提示:警报规则中使用的查询不能包含任何模板变量。目前我们只支持条件之间的AND和OR运算符，它们是串行执行的。 例如，我们按以下顺序有 3 个条件： 条件：A（计算为：TRUE）或条件：B（计算为：FALSE）和条件：C（计算为：TRUE） 所以结果将计算为（（对或错）和对）=对。 更多详细的告警规则可以查看官方文档:<a
