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

- [Quarantined objects] low: 4, high: 4, avg: 4, total: 4
- [Quarantined accounts] low: 0, high: 0, avg: 0, total: 0

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:
- */5 * * * * swift /usr/bin/swift-recon-cron /etc/swift/object-server.conf
