Brian, How can I get raw samples with exactly scraping time from Prometheus by the range query?
I use this call to query data , and use parameter step=30, curl --location --request GET 'http://xxx:9090/api/v1/query_range?query=node_processes_state{state%3D%27D%27}%20%3E%20500&start=2020-06-08T00:00:00Z&end=2020-06-09T18:00:00Z&step=30' api result below show that timestamp 1591607520, 1591607550, 1591607580 are not the scape time I guess.. "values": [ [ 1591607520, "2270" ], [ 1591607550, "2270" ], [ 1591607580, "2270" ], 在 2020年6月9日星期二 UTC+8下午11:16:49，Brian Brazil写道： > > On Tue, 9 Jun 2020 at 16:15, 林浩 <[email protected] <javascript:>> wrote: > >> when I use range query api to get data point, for example I using step 30s >> >> API return me data like these >> >> "values": [ >> [ >> 1591607520, >> "2270" >> ], >> [ >> 1591607550, >> "2270" >> ], >> [ >> 1591607580, >> "2270" >> ], >> >> for the UNIX timestamp, is that really reflex to scrap time? >> since I see some scrape setting >> >> global: >> scrape_interval: 2m >> scrape_timeout: 2m >> evaluation_interval: 1m >> >> >> because Prometheus using pull to get metric, so is there any way I can >> get precise scape UNIX timestamp from API ? >> > > You can use the timestamp() function, or use a query with a range vector > to get the raw samples. > > -- > Brian Brazil > www.robustperception.io > -- You received this message because you are subscribed to the Google Groups "Prometheus Users" group.
