Prometheus topk 返回的结果比预期的多 [英] Prometheus topk returns more results than expected

问题描述

如果我使用以下查询

topk(5,sum(container_memory_usage_bytes{kubernetes_container_name=~".+", kubernetes_namespace=~".+"}) by (kubernetes_namespace,kubernetes_container_name))

它返回 5 个预期结果.

it returns 5 results as epxected.

然而与

topk(5,sum(irate(container_cpu_usage_seconds_total{kubernetes_container_name=~".+", kubernetes_namespace=~".+"}[20s])) by (kubernetes_namespace,kubernetes_container_name))

返回大约 18 个结果.知道为什么会这样吗?我需要在第二个查询中更改什么才能只获得前 5 个?

around 18 results are returned. Any idea why this happens? And what I need to change in the second query to get only the top 5?

推荐答案

遇到了同样的问题，我在查询中打开了即时"，我得到了正确的金额

Had the same issue, I switched on "Instant" on the query and I got the correct amount back
