#openstack_swift_stats_ -- Plugin to monitor size of OpenStack Swift containers
|
|
#
|
|
#=head1 ABOUT
|
|
#
|
|
#Multigraph plugin. Graphs the following statistics about an OpenStack Swift container:
|
|
#- Size in bytes
|
|
#- Growth in size per graph period (hour by default)
|
|
#
|
|
#- Number of objects
|
|
#- Growth in objects per graph period (hour by default)
|
|
#
|
|
#=head1 CONFIGURATION

|
|
#Configuration values are mandatory. Names are identical to the environment values used by the Swift commands and passed directly to it.

#=head1 USAGE
|
|
#
|
|
#- Place the plugin in your plugins storage directory (/usr/share/munin/plugins)
|
|
#- Symlink it into the active plugins directory (/etc/munin/plugins) with the name of your container after the last underscore
|
|
# (e.g. ln -s /usr/share/munin/plugins/openstack_swift_stats_ /etc/munin/plugins/openstack_swift_stats_mycontainer)
|
|
#- Copy the OpenStack login environment variables from the openrc.sh file provided by your hosting provider to your plugin config file as shown in the configuration section.
|
|
#- Add the OS_PASSWORD value for the chosen user.
