问题描述
我使用 Prometheus 来衡量业务指标，例如:
I used Prometheus to measure business metrics like:
# HELP items_waiting_total Total number of items in a queue
# TYPE items_waiting_total gauge
items_waiting_total 149
我想长期保留这些数据(保留 5 年)，并且我不需要在 scrape_interval 中使用高频率.所以我设置了scrape_interval: "900s".
I would like to keep this data for very long term (5 years retention) and I don't need high frequency in scrape_interval. So I set up scrape_interval: "900s".
当我在 Prometheus 中以 60 秒的分辨率查看图形时，它显示了扑动，但事实并非如此.
When I check the graph in Prometheus with 60s resolution, it shows that flapping, but it is not true.
问题是，Prometheus 中的最大(推荐)scrape_interval 是多少?
The question is, what is the maximum (recommended) scrape_interval in Prometheus?
推荐答案
最好不要超过 2 分钟.这是因为默认情况下过时是 5 分钟(这就是造成间隙的原因)，并且您希望允许刮擦失败.
It's not advisable to go above about 2 minutes. This is as staleness is 5 minutes by default (which is what's causing the gaps), and you want to allow for a failed scrape.
