I am wondering if there is an interface where I can delete metrics, logs and traces in Prometheus, Loki and Tempo. I expected there is sth like a button with: delete anything older than x days or set a retention period on specific timeseries.
@jangaraj: Yes, that helps a little bit but I think I have found the solution.
It does not matter as you are only payed for active time series. So as soon as you do not feed a time series anymore, you do not pay for it (Grafana Cloud). So at least the next month it does not matter anymore.
Loki: there is an API.
Prometheus, does not matter
But what about Tempo? I did not find a API but it seems there is a “compactor” that delets traces after some time. Does anyone now how this time is defined in Grafana Cloud and is there the option to change that?
