I’ve been configuring to see how can I extend the retention period for the metrics data that sent over to my dashboard.
I attempt to change the retention period to 3 months as below.
But I still couldn’t manage to see the metrics kept for 3 months - it still keeps for 15 days only.
Can I please ask how to achieve for seeing the metrics data for 3 months and if my retention setup is correct under prometheus.service config file?
Please advise, many thanks.
