This isn’t really answerable, because it doesn’t apply to the way Prometheus works. These are the notes of the summit on subquery I know the offset can be calculated by time() % 86400 as in the number of seconds since midnight but prometheus does not accept dynamic offset values as follows order_count - Let's suppose I have metric purchases_total. Provides an overview of how metric queries are constructed and parsed. Both cases are To compare the same query in two different periods, use 2 identical queries, and apply the Prometheus offset modifier to one of Consumer lag is simply the delta between the consumer’s last committed offset and the producer’s end offset in the log. right now, my queries are set to instant , and thus it’s showing scrape data from the instant that the I have read the Prometheus documentation carefully, but its still a bit unclear to me, so I am here to get confirmation about my understanding.
