Prometheus：根据另一个指标过滤查询

Question

假设我在普罗米修斯中有两个指标，都是计数器：

• requests_processed_total
• requests_failed_total

他们都有一个匹配的service标签。例子：

requests_processed_total{service="news"} 1097
requests_processed_total{service="store"} 487
requests_failed_total{service="news"} 23
requests_failed_total{service="store"} 89

如何查询requests_failed_total，但仅限于其服务request_processed_total > 1000。

我期待以下回复：

requests_failed_total{service="news"} 23

# Note that the "store" service is excluded

Answer 1

requests_failed_total and on(service) requests_processed_total > 1000
