【问题描述】：

我在 Prometheus 中加载了一些自定义指标

我写了这个 API 请求

http://prometheus01/api/v1/query_range?query=count(kpi_metrics)&start=1515747230&end=1515750830&step=60

{"status":"success","data":{"resultType":"matrix","result":[{"metric":{},"values":[[1515747230,"39"],[1515747290,"39"],[1515747350,"39"],[1515747410,"39"],[1515747470,"39"],[1515747530,"39"],[1515747590,"39"],[1515747650,"39"],[1515747710,"39"],[1515747770,"39"],[1515747830,"39"],[1515747890,"39"],[1515747950,"39"],[1515748010,"39"],[1515748070,"39"],[1515748130,"39"],[1515748190,"39"],[1515748250,"39"],[1515748310,"39"],[1515748370,"39"],[1515748430,"39"],[1515748490,"39"],[1515748550,"39"],[1515748610,"39"],[1515748670,"39"],[1515748730,"39"],[1515748790,"39"],[1515748850,"39"],[1515748910,"39"],[1515748970,"39"],[1515749030,"39"],[1515749090,"39"],[1515749150,"39"],[1515749210,"39"],[1515749270,"39"],[1515749330,"39"],[1515749390,"39"],[1515749450,"39"],[1515749510,"39"],[1515749570,"39"],[1515749630,"39"],[1515749690,"39"],[1515749750,"39"],[1515749810,"39"],[1515749870,"39"],[1515749930,"39"],[1515749990,"39"],[1515750050,"39"],[1515750110,"39"],[1515750170,"39"],[1515750230,"39"],[1515750290,"39"],[1515750350,"39"],[1515750410,"39"],[1515750470,"39"],[1515750530,"39"],[1515750590,"39"],[1515750650,"39"],[1515750710,"39"],[1515750770,"39"],[1515750830,"39"]]}]}}

这很好。

如果值满足条件，我想获取信息之后

kpi_metrics<1

我写了 API 请求

http://prometheus01/api/v1/query_range?query=count(kpi_metrics<1)&start=1515747230&end=1515750830&step=60

但普罗米修斯只返回了

{"status":"success","data":{"resultType":"matrix","result":[]}}

如何根据条件kpi_metrics

【问题讨论】：

标签： prometheus

【解决方案1】：

查询结果正确，kpi_metrics的时间序列均为39，不小于1。

【讨论】：

如果结果为空，是否有可能以某种方式返回例如零？
你想要kpi_metrics< bool 1。
我只想得到满足 kpi_metrics 条件的 kpi_metrics
