which way is the right for remove files in ../Introscope_Collector/data/archive??
If you are interested in reducing the Smartstor database I would suggest to use Smartstor tools (see CA Configuration and Administration guide). Otherwise if you are not interested in historical metrics then stop the EM and remove "data" folder manually (take a backup prior deleting). Once you restart the EM the "data" folder will be recreated automatically and you will have a fresh Smartstor db.
