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.

Finally if you also wish to track asynchronous pending’s you will need to setup a
cronjob to run the swift-recon-cron script periodically:
.IP "*/5 * * * * swift /usr/bin/swift-recon-cron /etc/swift/object-server.conf"
