NAME

       swift-recon - Openstack-swift recon middleware cli tool

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.

EXAMPLE

       ubuntu:~$ swift-recon -q --zone 3
       =================================================================
       [2011-10-18 19:36:00] Checking quarantine dirs on 1 hosts...
       [Quarantined objects] low: 4, high: 4, avg: 4, total: 4
       [Quarantined accounts] low: 0, high: 0, avg: 0, total: 0
       [Quarantined containers] 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
