hi Clark,
Our applications are telco based applications. So far, they have
been using push model for every 5 minutes. The every 5 minute is a
telecom standard guideline. We thought of consume those files every 5
minutes from our custom exporter. We can't miss the second, Is there
any way in prometheus to accomplish this ?
The maximum scrape rate for Prometheus is about 2 minutes due to
staleness.
Can you switch to say scraping every minute?

Both are expected.
The scrape interval is an average, so gaps between scrapes might be
a bit longer or shorter each time. Different scrapes with the same
scrape interval will happen at different times to prevent everything
happening at once, overwhelming the server and network.
Ideally most metrics should be counters rather than gauges which are
a lot more resistant to slight differences in timings between
scrapes and across jobs & targets.

hi All,
We are running prometheus server in our testing environment
which scraps 3 different exporters.( node exporter, kafka exporter
and custom exporter).
1. All the three exporters are pulling its metrics in different
timing even though the scrap interval are same. Is it expected
behaviour ?
2. Our application's very time sensitive, we would like to
scrap for every 60 seconds. But we could see the collection time
difference are like 61 seconds or 62 seconds at sometimes. Is
there any way to make it consistent ? Or Is it expected behaviour
?
