NAME

       swift-dispersion-populate - Openstack-swift dispersion populate

SYNOPSIS

       swift-dispersion-populate [--container-suffix-start] [--object-suffix-start] [--container-
       only|--object-only] [--insecure] [conf_file]

DESCRIPTION

       This is one of the swift-dispersion utilities that is used to evaluate the overall cluster
       health.  This  is accomplished by checking if a set of deliberately distributed containers
       and objects are currently in their proper places within the cluster.

       For instance, a common deployment has three replicas of each object.  The health  of  that
       object  can  be  measured by checking if each replica is in its proper place. If only 2 of
       the 3 is in place the object's health can be said to be at 66.66%,  where  100%  would  be
       perfect.

       We  need  to  place  the  containers and objects throughout the system so that they are on
       distinct partitions. The swift-dispersion-populate tool does  this  by  making  up  random
       container  and  object  names until they fall on distinct partitions. Last, and repeatedly
       for the life of the cluster, we need to run the swift-dispersion-report tool to check  the
       health of each of these containers and objects.

       These  tools  need  direct access to the entire cluster and to the ring files.  Installing
       them on a proxy server will probably do or a box used for  swift  administration  purposes
       that also contains the common swift packages and ring.  Both swift-dispersion-populate and
       swift-dispersion-report use the same configuration file, /etc/swift/dispersion.conf .  The
       account used by these tool should be a dedicated account for the dispersion stats and also
       have admin privileges.

OPTIONS

       --insecure
              Allow accessing insecure keystone server. The keystone's certificate  will  not  be
              verified.

       --container-suffix-start=NUMBER
              Start container suffix at NUMBER and resume population at this point; default: 0

       --object-suffix-start=NUMBER
              Start object suffix at NUMBER and resume population at this point; default: 0

       --object-only
              Only run object population

       --container-only
              Only run container population

       --object-only
              Only run object population

CONFIGURATION

       Example /etc/swift/dispersion.conf:

          [dispersion]
          auth_url = https://127.0.0.1:443/auth/v1.0
          auth_user = dpstats:dpstats
          auth_key = dpstats
          swift_dir = /etc/swift
          # dispersion_coverage = 1.0
          # retries = 5
          # concurrency = 25
          # endpoint_type = publicURL

EXAMPLE

       $ swift-dispersion-populate
        Created 2621 containers for dispersion reporting, 38s, 0 retries
        Created 2621 objects for dispersion reporting, 27s, 0 retries
