Hi Dhanush, The way Prometheus works (usually) is that it scrapes the current value of all metrics from a target / exporter. So a /metrics endpoint does not provide historical data, the history only gets built up by Prometheus itself as a process of scraping and storing current values periodically in the time series database. So if you only have been scraping for 2h, it's expected that you would only get 2h of data in your TSDB.
