Ganz GXi Series VCA Interface Manual V3.05.31.18 Total DB Size The maximum size of the database when internal flash is selected as the storage medium is 512KB. The display shows how much storage is in use out of the total available. If the configuration of the database tables would cause the storage requirement to exceed the maximum the user is warned before the settings can be applied. Database Table Configuration The database allows up to 4 tables to be configured (0-3). Each table can sample the counter values at different intervals, thus allowing reports that cover different granularities and time windows to be generated by the user. Tables must be enabled in-order. For example, Table 0 must be enabled before Table 1 can be enabled. Sampling Interval How frequently the counter values are sampled and stored to the database. Specified in minutes. Roll-over Count The total number of records to store in the database table. When this number of records have been added to the table, the table wraps-around and overwrites the oldest data. Max Roll-over Time Shows the maximum time that the table will hold counting data for. Calculated as follows: Max Roll-over Time (minutes) = Sampling Interval x Roll-over Count Database Management Functions for managing the database. Clear Wipes all data from all database tables. Backup Allows the user to download a backup of the database tables into a file that can be restored later. Restore Restore a previously downloaded backup back into the database tables. 05-2018-A 68 | P a g e
