You can manage the size of the Analyzer detail view database based on time (age of the data), current size, and amount of available disk space. You can put limits on the performance database to purge the performance data. (You cannot purge the configuration data.)
On the Analyzer detail view server, the performance data is stored in: /usr/local/megha/db/perf/date (the date format is: YYYYMMDD).
Each date folder contains performance data for one day.
You can also manage the size of the backup and meghadata directories based on time (age of data).
