Find out current retention period for monitoring servers and ensure that data is kept for 5 years

Description
- Looking at monitoring.place6 I see data for less than 90 days.
- My expectation is to be able to zoom out to 5 years so that we can see changes we did over years
- My assumption is that prometheus is configured with some storage size and it auto drops/rotates
- So probably the solution is just to add/extend the hdd space on monitoring.placeX by a factor of Y
it's configured in __dcl_monitoring_server type
...
__prometheus_server \
--config "$prometheus_config" \
--retention-days 30 \
--rule-files "$__type/files/*.rules" \
--storage-path /data/prometheus
...
on the __prometheus_server you see:
...
FLAGS="--storage.tsdb.path $storage_path --storage.tsdb.retention $((retention_days*24))h --web.listen-address [::]:9090"
...
See here for the configuration
https://www.robustperception.io/configuring-prometheus-storage-retention
I suggest to use the flag --storage.tsdb.retention.size 90GB (not sure if 90GB works) and get rid of the --storage.tsdb.retention flag
Here some interesting information about prometheus storage handling https://prometheus.io/docs/prometheus/1.8/storage/
