.SH SYNOPSIS
.LP
.B swift-recon
\ <server_type> [-v] [--suppress] [-a] [-r] [-u] [-d] [-l] [-T] [--md5] [--auditor] [--updater] [--expirer] [--sockstat]

.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.

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:
