It would be nice if the "Storage Server" sub-page of the Welcome Page would show an estimate of how much space the storage server is using. This estimate could be built by one of the share-crawlers, by adding up how much space is used in each prefix directory. A loose estimate could be maintained cheaply by summing the last-known-size for each prefixdir, and updating one prefixdir per time period (as all crawlers do). Since shares are placed pseudo-randomly, an even looser and cheaper estimate could be made by measuring a fraction of the prefixdirs and multiplying.

The bucketcrawler doesn't look inside the bucket directories, but the lease-crawler does. Let's add "space consumed" functionality to the lease-crawler, and display the results on the storage-server WUI page.

See also #671 (bring back sizelimit (i.e. max consumed, not min free)).

See also #1836, which is to get this information from leasedb instead of share crawler. Changing the title of this ticket to make it independent of where the information comes from.

zooko changed title from ~~share-crawler should estimate+display space-used~~ to display space-usage configs, space used, space available for your storage server

See also #648 which is for the client to display to its user the space-usage/space-available information about storage servers that it knows about.

See also #666 which is for the server to display to its user the space used up by its clients. (Among several other features that are part of #666.)
