AlertManager datasource

Hello Team,

I am searching information regarding data history for Alertmanager datasource. In my use case, my panel retrieve information from Alertmanager for a 24 hours duration.

I know that Alertmanager does not store past alerts, does it mean that Grafana will continously pull data from Alertmanager, does it work with Dashboard refresh function ?

Do you have some info about this configuration ?

I know there is a way to store alerts into a MySQL DB and use Mysql data source with Grafana.

Thanks for your help.
