What is the maximum scrape_interval in Prometheus

Question

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_waitin         


        

Answer 1

If you want to ignore gaps, it is possible to use some aggregation_over_time functions to get your DATA from Prometheus.

max_over_time(items_waiting_total[900s])

This is useful for situations where frequent gathering of DATA is expensive for collector.
