Throughput Performance Plugin.

The FTP Throughput Performance plugin allows the user to obtain calculated performance information for all types of transfers except a third party transfer in which Extended Block mode is not enabled.

Note: Since this plugin is built on top of the Performance Marker Plugin, it is not possible to associate both plugins with a handle

Module descriptor

Transfer begin callback

This callback will be called when a transfer begins

Parameters

handle The client handle associated with this transfer
user_specific User argument passed to globus_ftp_client_throughput_plugin_init
source_url source of the transfer (GLOBUS_NULL if 'put')
dest_url dest of the transfer (GLOBUS_NULL if 'get')

Returns

•
n/a

Transfer complete callback

This callback will be called upon transfer completion (successful or otherwise)

Parameters

handle The client handle associated with this transfer
user_specific User argument passed to globus_ftp_client_throughput_plugin_init
success indicates whether this transfer completed successfully or was interrupted (by error or abort)

Returns

•
n/a

Stripe performance throughput callback

This callback will be called with every performance callback that is received by the perf plugin. The first callback for each stripe_ndx will have an instantaneous_throughput based from the time the command was sent.

Parameters

handle The client handle associated with this transfer
user_specific User argument passed to globus_ftp_client_throughput_plugin_init
bytes The total number of bytes received on this stripe
instantaneous_throughput Instanteous throughput on this stripe (bytes / sec)
avg_throughput Average throughput on this stripe (bytes / sec)
stripe_ndx This stripe's index

Total performance throughput callback

This callback will be called with every performance callback that is received by the perf plugin. The first callback for will have an instantaneous_throughput based from the time the command was sent. This callback will be called after the per_stripe_cb

Parameters

handle The client handle associated with this transfer
user_specific User argument passed to globus_ftp_client_throughput_plugin_init
bytes The total number of bytes received on all stripes
instantaneous_throughput Total instanteous throughput on all stripes (bytes / sec)
avg_throughput Average total throughput on all stripes (bytes / sec)

Copy constructor

This callback will be called when a copy of this plugin is made, it is intended to allow initialization of a new user_specific data

Parameters

user_specific this is user specific data either created by this copy method, or the value passed to init

Returns

  • a pointer to a user specific piece of data
  • GLOBUS_NULL (does not indicate error)

Destructor

This callback will be called when a copy of this plugin is destroyed, it is intended to allow the user to free up any memory associated with the user specific data

Parameters

user_specific this is user specific data created by the copy method

Returns

•
n/a

Destroy throughput plugin

Frees up memory associated with plugin

Parameters

plugin plugin previously initialized with init (above)

Returns

  • GLOBUS_SUCCESS
  • Error on NULL plugin

Retrieve user specific pointer

Parameters

plugin plugin previously initialized with init (above)
user_specific pointer to storage for user_specific pointer

Returns

  • GLOBUS_SUCCESS
  • Error on NULL plugin
  • Error on NULL user_specific

Throughput plugin init

Use this function to initialize a throughput plugin. The throughput plugin sits on top of the perf_plugin. The only required param is 'plugin', all others may be GLOBUS_NULL

Parameters

plugin a pointer to a plugin type to be initialized
begin_cb the callback to be called upon the start of a transfer
per_stripe_cb the callback to be called every time updated throughput info is available for a given stripe
total_cb the callback to be called every time updated throughput info is available for any stripe
complete_cb the callback to be called to indicate transfer completion
user_specific a pointer to some user specific data that will be provided to all callbacks

Returns

  • GLOBUS_SUCCESS
  • Error on NULL plugin
  • Error on init perf plugin

Set user copy and destroy callbacks

Use this to have the plugin make callbacks any time a copy of this plugin is being made. This will allow the user to keep state for different handles.

Parameters

plugin plugin previously initialized with init (above)
copy_cb func to be called when a copy is needed
destroy_cb func to be called when a copy is to be destroyed

Returns

  • Error on NULL arguments
  • GLOBUS_SUCCESS
