The standard maximum scape interval is about 2 minutes, due to staleness 
- less frequent scrapes would likely cause series to be marked as stale 
and therefore disappear from alerts/dashboards.

[BHARATH KUMAR]

Hello all,

Q1) What will happen if we set scrape interval as 5 minutes or 10 minutes?
Q2) I am observing some misbehavior when we set different scrape interval. 
what is the reason behind that?


Could you please answer those questions?

Thanks in advance.

Re: [prometheus-users] scrape_interval is not working properly.

[Ben Kochie]

You didn't provide any evidence of why you think it's not working. You need
to include more information.

[prometheus-users] scrape_interval is not working properly.

[Byungkwon Choi]

Hello,

I want to collect the HTTP requests per second every second.
To do so, I'm using Prometheus and Prometheus Adapter.

I set the value of 'scrape_interval', 'scrape_timeout', and 
'evaluation_interval' to 1s in the Prometheus ConfigMaps resource of K8S as 
follows:

[image: 스크린샷 2020-08-05 오전 12.20.46.png]


I use the following query to collect HTTP requests per second:
sum(irate(request_total{namespace!="", direction="inbound"}[30s])) by 
(deployment)

However, the value of the query is updated almost every 20 seconds.
What I expect to this value is to be updated every second because I use 
'irate' here and set 'scrape_interval' to 1 second.


My current environment is as follows:

   - Service mesh: Linkerd v2.8.1
   - K8S version: v1.17.9
   - CNI: Calico
   - Other components deployed together: Jaeger, Prometheus-adapter


Did I miss something?
Thank you in advance!
