Max_open_conn for mysql datasource


I have a dashboard with 3 graphs, each with 3 metrics.
all queries are quite heavy on the DB (~5 each when run with no other load on the DB), but they become much worse when executed in parallel.

is there a way to instruct grafana to perform those queries one after the other instead of in parallel?

ini grafana.ini, [database].max_open_conn limits the number of connections to the configuration database.
is there a way to do the same for a mysql datasource?



No, that’s not supported.

No, not now but there are an open issue for it.
