What is the recommended Scrape interval

[kiran]

Hello all

I have seen many use 15s. Couple of questions:

1. What is the recommended scrape_interval to use?

2. Any issues using lower scrape_intervals like 1s or 5s?

It depends by you. For me, I run the websites not that important, so I
setup interval to 1min. And I have seen many others setup it to 10s or
shorter. I don't think 1s is good choice, it may increase the overload
of Prometheus server.

Regards.

Can the scrape interval be set at job level?

Sure you can. I have done with this.

In addition to the load on the Prometheus server, a scrape interval of 1s means the scrape timeout is 1s. So you need very reliable and fast networking, servers, and targets to make sure that the scrapes completely quickly enough.
