how to tune metrics in ambari in order to purge old data

how to tune metrics in ambari in order to purge old data

 

hi all

 

since some ambari clusters are with implemented ambari-metrics-collector in embedded mode.

 

we want to decrease the metrics data to 6 month , and purge the metrics that saved more then 6 month

 

is it possible?
