fdb stats¶

Prints information about FDB databases, aggregating the information over all the databases visited into a final summary.

Usage¶

fdb stats [options] [request1] [request2] ...

Options¶

`--details`	Print information for each database visited, in addition to the summary
`--ignore-errors`	Ignore errors (report them as warnings) and continue processing wherever possible
`--raw`	Don’t apply (contextual) expansion and checking on requests. Keys and values passed must match those used internally to the FDB exactly. This prevents the use of named parameters (such as t rather than param=130), dates (such as date=-1), or similar.
`--minimum-keys`	Default is class,expver Define the minimum set of keys that must be specified. This prevents inadvertently exploring the entire FDB.
`--all`	(Debug and testing only) Visit all FDB databases
`--config=string`	FDB configuration filename.

Example 1¶

You may pass a partial request (as a key) that will print information on all FDB databases that match that key.
