Hi Amin, There's no built-in way to do 2) in Prometheus, so either you would have to build new tooling (probably in Go) for this or maybe it could be done in a relatively inefficient way like this:
1) Use "promtool tsdb dump" to dump your old data into a file. 2) Change the formatting of that file to valid OpenMetrics (e.g. insert "# EOF" to terminate metric groups, etc., see for example "OpenMetrics Novelties" in https://sysdig.com/blog/openmetrics-is-prometheus-unbound/). 3) Delete the old TSDB block dirs in your Prometheus data directory. 4) Backfill the OpenMetrics file using "promtool tsdb create-blocks-from openmetrics" (see https://prometheus.io/docs/prometheus/latest/storage/#backfilling-from-openmetrics-format ) On Sun, Apr 17, 2022 at 12:54 PM Amin Borjian <[email protected]> wrote: > Hi. > > We are looking to rename some of the metrics name (metric X -> Y). > However, we do not want lose old data that has already been collected and > stored by Prometheus in TSDB. history of metric is important for us. > > We are looking for the following way: > 1) Change the name of the metric, as a result of which the metric will be > saved with a new name from now on. > 2) After the above change, change the name of the old metrics in the > Prometheus database. > > But we did not find a way for the second part.
