The policy of giving projects vanity domains stopped about 5 years ago. swift.openstack.org is a redirect to the canonical location - docs.openstack.org/developer/swift. While we are not aiming to remove the redirect any time in the forseeable future due to existing published links pointing to it, we should at the very least stop adding more of those links to the world.

.SH DESCRIPTION
|
||
.PP
|
||
The swift-recon cli tool can be used to retrieve various metrics and telemetry information about
|
||
a cluster that has been collected by the swift-recon middleware.
|
||
|
||
In order to make use of the swift-recon middleware, update the object-server.conf file and
|
||
enable the recon middleware by adding a pipeline entry and setting its option(s). You can view
|
||
more information in the example section below.
