I have a cluster of containers, exactly Docker Swarm.
I deployed the Grafana Service (grafana in a docker).
Grafana open successfully, I can configure dashboards successfully too, etc
But the history only has a duration of 24hours, why?
I mean, I only have a day as history in all my dasboards.
How do I can solve this problem?
I inform you, my data sources is zabbix + postgresql.
For example, at 4:30PM, my graph only save last 24 hours.
Thanks for your help
