What do you mean? 1. Create an alert now, on the value of data as it was some time in the past? Sure: use "expr: foo offset 2d > 123", or use a range vector query such as "expr: min_over_time(foo[2d]) < 123"
2. View the values of historic data, that created an alert some time ago? Sure: if the expression is "expr: foo > 123" then just enter "foo" or "foo > 123" into the PromQL browser and you'll see its history. 3. To find out what alerts had been triggered in the past? Have a look at these auto-generated metrics: ALERTS ALERTS_FOR_STATE Also, if you are scraping alertmanager's own /metrics endpoint, then you'll have various alertmanager_* metrics as well, including alertmanager_alerts (which gives the number of alerts firing at a particular time), and various counters for delivery and failure to deliver alerts to different integrations. -- You received this message because you are subscribed to the Google Groups "Prometheus Users" group.
