Detailed Description

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

Typedef Documentation

typedef void(* globus_ftp_client_throughput_plugin_begin_cb_t)(void *user_specific, globus_ftp_client_handle_t *handle, const char *source_url, const char *dest_url)

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

typedef void(* globus_ftp_client_throughput_plugin_complete_cb_t)(void *user_specific, globus_ftp_client_handle_t *handle, globus_bool_t success)

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

typedef void(* globus_ftp_client_throughput_plugin_stripe_cb_t)(void *user_specific, globus_ftp_client_handle_t *handle, int stripe_ndx, globus_off_t bytes, float instantaneous_throughput, float avg_throughput)

Stripe performace 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

typedef void(* globus_ftp_client_throughput_plugin_total_cb_t)(void *user_specific, globus_ftp_client_handle_t *handle, globus_off_t bytes, float instantaneous_throughput, float avg_throughput)

Total performace 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)

typedef void*(* globus_ftp_client_throughput_plugin_user_copy_cb_t)(void *user_specific)

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)

typedef void(* globus_ftp_client_throughput_plugin_user_destroy_cb_t)(void *user_specific)

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

Function Documentation

globus_result_t globus_ftp_client_throughput_plugin_destroy ( globus_ftp_client_plugin_t *plugin)

Destroy throughput plugin
Frees up memory associated with plugin
Parameters:
plugin plugin previously initialized with init (above)
Returns:
GLOBUS_SUCCESS
Error on NULL plugin

globus_result_t globus_ftp_client_throughput_plugin_get_user_specific ( globus_ftp_client_plugin_t *plugin, void **user_specific)

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

globus_result_t globus_ftp_client_throughput_plugin_init ( globus_ftp_client_plugin_t *plugin, globus_ftp_client_throughput_plugin_begin_cb_tbegin_cb, globus_ftp_client_throughput_plugin_stripe_cb_tper_stripe_cb, globus_ftp_client_throughput_plugin_total_cb_ttotal_cb, globus_ftp_client_throughput_plugin_complete_cb_tcomplete_cb, void *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

globus_result_t globus_ftp_client_throughput_plugin_set_copy_destroy ( globus_ftp_client_plugin_t *plugin, globus_ftp_client_throughput_plugin_user_copy_cb_tcopy_cb, globus_ftp_client_throughput_plugin_user_destroy_cb_tdestroy_cb)

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
