AFAIK, prometheus depend on scrape interval to determine timestamp of datapoints, if it schedules scrape at different interval, this assume may not be held.

Hello all,

I was thinking that if you use the same scrape-interval for many targets, doesn't this mean every 15/30/60s your Prometheus server sends out a huge barrage of requests all at once, potentially to many modules on the same
server?

I wondered if this can lead to any issues with network spikes and so on, and if Prometheus allows/encourages all the various scrapes to be staggered slightly so there is a constant stream of polls not so 'lumpy'? Maybe it naturally works this way anyway, that polls are run sequentially rather
than in parallel?

Thanks for any insight,
John.
