i create a new Postgres Database connection. In This DB there is a table which contains information for some Backups. The Table “Backup” contains a Success 1 or 0 and write every hour one row.
So far all is working.
Now i want to make an notification in Grafana, when is now row last1-2h or the row contains 0 instead 1, then should send an notifications. But this is not working. How can i resolve this ?
