I think you are mixing two things.
- how many days transaction trace should be stored.
- how may days metrics will be stored in SmartStor database
Transaction traces are saved in traces folder and default value is 14 days. you can increase or decrease these days but if you are increasing make sure you have enough storage capacity to store bunch of traces.
# How many days to store traces
introscope.enterprisemanager.transactionevents.storage.max.data.age=14
Metrics data are store in /data folder by default it is more than a year and following are the settings you will find in properties file.
# cannot define more than three tiers.
introscope.enterprisemanager.smartstor.tier1.frequency=15
introscope.enterprisemanager.smartstor.tier1.age=7
introscope.enterprisemanager.smartstor.tier2.frequency=60
introscope.enterprisemanager.smartstor.tier2.age=23
introscope.enterprisemanager.smartstor.tier3.frequency=900
introscope.enterprisemanager.smartstor.tier3.age=120
you can still edit these value to increase or decrease # of days.
