如何从Prometheus查询API延迟错误预算

我有一个普罗米修斯柱状图，

api\u response\u duration\u seconds

，其中的SLO定义为

histogram_quantile(0.95, sum(increase(api_response_duration_seconds_bucket[1m])) by (le)) <= 0.5

---

histogram\u quantile（0.95，sum（增加（api\u response\u duration\u seconds\u bucket[1m]）到（le））所以这里的秘密是我想把一个范围向量转换成一个范围向量。这个

因此，需要做的是：

groups:
  - name: SLOs
  - rules:
    - record: slo:api_response_duration_seconds:failing
      expr: histogram_quantile(0.95, sum(increase(api_response_duration_seconds_bucket[1m])) by (le)) > 0.5
    - record: slo:api_response_duration_seconds:all
      expr: histogram_quantile(0.95, sum(increase(api_response_duration_seconds_bucket[1m])) by (le))

然后按如下方式查询错误预算：

count_over_time(slo:api_response_duration_seconds:failing[28d])
/
count_over_time(slo:api_response_duration_seconds:all[28d])
