The AppDynamics Controller properties that govern how long metric data is retained in the database are1:
metrics.ten.min.retention.period: This property specifies the number of days to retain metric data at 10-minute granularity. The default value is 32 days.
metrics.retention.period: This property specifies the number of days to retain metric data at 1-hour granularity. The default value is 365 days.
metrics.min.retention.period: This property specifies the number of hours to retain metric data at 1-minute granularity. The default value is 4 hours.
The other options are incorrect because1:
metrics.ten.sec.retention.period: This property does not exist in the AppDynamics Controller. The finest granularity for metric data is 1 minute.
metrics.day.retention.period: This property does not exist in the AppDynamics Controller. The coarsest granularity for metric data is 1 hour.
metrics.week.retention.period: This property does not exist in the AppDynamics Controller. The metric data retention is based on days, not weeks. References: Database Size and Data Retention
