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.

        Perform all checks. Equivalent to -arudlqT --md5 --sockstat --auditor --updater --expirer --driveaudit --validate-servers

    --region=REGION
        Only query servers in specified region

    -z ZONE, --zone=ZONE
        Only query servers in specified zone

    -t SECONDS, --timeout=SECONDS
        Time to wait for a response from a server

    --swiftdir=PATH

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
