HI everyone, I am new t Prometheus, can anyone let me know: Is it possible to replace the existing time series with new scrapped data. For example: at metric end: metric_example(name:"abc") 1 metric_example(name:"xyz") 2So for this Prometheus server will have two timeseries as: metric_example{instance:"192.168.47.53",job:"example",name:"abc"} 1 metric_example{instance:"192.168.47.53",job:"example",name:"xyz"} 2 IS IT POSSIBLE THAT ON PROMETHEUS THE FIRST TIMESERIES GET REPLACED WITH THE SECOND ONE, WHEN THE SECOND ONE GETS SCRAPPED FROM METRIC END?
Each combinations of labels (including the metric name) is stored as a separate time series. So in your example there are two time series, as the "name" label is different. You are free to stop (or start) sending a particular label combination (or even a whole metric). After 5 minutes a time series that is no longer being presented during the scrapes will be marked as "stale" and would stop appearing on graphs, alerts, etc. (unless you do a query which covers a period before it goes stale).
