user list

Well, there's no easy way, but there is a way.

You can find all the account databases on a node by looking in /srv/node/*/accounts/**/*.db (e.g. "find /srv/node/*/accounts -name '*.db'"), and then query each one of those for its account name ("SELECT account FROM account_stat"). Do that across all your nodes and deduplicate the list, and you've got all the accounts in your system.

With that in hand, you can do a series of HEAD requests to see how much stuff is stored under each account.

This is kind of what I expected, but not what I wanted. Maybe its time to write a blueprint for an easier way to do this.

Sure. If you want to have a go at coding it yourself, one fairly easy way would be to make the account auditor log the name of the account it's auditing (in, say, AccountAuditor.account_audit). Then getting a list of all accounts becomes a matter of log parsing.

I've only spent a minute or two thinking about this, though, so don't take the above as some sort of hard requirement. :)

Doesn't slogging already make a pretty good run at this?
