Jay Harris is Cpt. LoadTest

Have tried this code. But it not worked. Giving several errors.

Here is the total code in a .usr file that I put.

==============================================================

#include "web_api.h"

Action()
{
int si_page_size_limit(int PageLimit, char* PageName, char *PageURL, long TransactionID);
{
int iPageSize = web_get_int_property(HTTP_INFO_DOWNLOAD_SIZE);
char DataPointName[1024] = "Response Size [";
strcat(DataPointName, PageName);
strcat(DataPointName, "]");

if (PageLimit < iPageSize)
{
lr_continue_on_error(1);
lr_debug_message(LR_MSG_CLASS_BRIEF_LOG | LR_MSG_CLASS_EXTENDED_LOG,
"Page Size Check FAILED - %s [%s] exceeds specified page size limit of %d (Total: %d)",
PageName,PageURL,PageLimit,iPageSize);
lr_continue_on_error(0);
}
else
{
lr_debug_message(LR_MSG_CLASS_BRIEF_LOG | LR_MSG_CLASS_EXTENDED_LOG,
"Page Size Check PASSED - %s [%s] meets specified page size limit of %d (Total: %d)",
PageName,PageURL,PageLimit,iPageSize);
}
if (lr_get_trans_instance_status(TransactionID) == LR_PASS)
{
lr_user_data_point_instance_ex(DataPointName,iPageSize,TransactionID,DP_FLAGS_EXTENDED_LOG);
}

return 0;
}
return 0;
}

============================================

On compiling It is generating errors like following.

===========================================

Action.c (6): illegal expression
Action.c (6): syntax error; found `PageLimit' expecting `)'
Action.c (6): syntax error; found `PageLimit' expecting `;'

I have modified the script like the following.

=========================================
#include "web_api.h"

Action()
{
int si_page_size_limit();
{
int PageLimit = 500;
char* PageName = "Google";
char *PageURL = "http://google.co.in";
long TransactionID = 2;

int iPageSize = web_get_int_property(HTTP_INFO_DOWNLOAD_SIZE);
char DataPointName[1024] = "Response Size [";
strcat(DataPointName, PageName);
strcat(DataPointName, "]");

if (PageLimit < iPageSize)
{
lr_continue_on_error(1);
lr_debug_message(LR_MSG_CLASS_BRIEF_LOG | LR_MSG_CLASS_EXTENDED_LOG,
"Page Size Check FAILED - %s [%s] exceeds specified page size limit of %d (Total: %d)",
PageName,PageURL,PageLimit,iPageSize);
lr_continue_on_error(0);
}
else
{
lr_debug_message(LR_MSG_CLASS_BRIEF_LOG | LR_MSG_CLASS_EXTENDED_LOG,
"Page Size Check PASSED - %s [%s] meets specified page size limit of %d (Total: %d)",
PageName,PageURL,PageLimit,iPageSize);
}
if (lr_get_trans_instance_status(TransactionID) == LR_PASS)
{
lr_user_data_point_instance_ex(DataPointName,iPageSize,TransactionID,DP_FLAGS_EXTENDED_LOG);
}

return 0;
}
return 0;
}

=========================================================

This removed errors but I am still not getting proper results.

In addtion to that can you please explain where will I gat the details about the page sizes?

Is this how you would set up your HTTP size monitoring? (sorry, I have not figured out how to make the code pretty)

//--------------------------------------------------------------------------------------------------
// The following should be in the vuser_init procedure
vuser_init()
{
return 0;
}

int txnHandle; // There should be one txnHandle int variable for each transaction in the LR script.
int MAX_PAGE_SIZE = 1048576; // 1MB, others may have different size limitations

si_page_size_limit(int PageLimit, char* PageName, char *PageURL, long TransactionID)
{
//

// Rest of si_page_size_limit omitted.

return 0;
}

//--------------------------------------------------------------------------------------------------

// The following is an example for running download size monitoring.
// This kind of code would be scattered throughout the Action procedures.

lr_start_transaction_instance("TransactionName", 0);
si_page_size_limit(
MAX_PAGE_SIZE,
"pageName",
"http://some.page.URL",
txnHandle);

// Code for actually interacting with the page.

lr_stop_transaction_instance(txnHandle);

// Other LR code, some of which may involve invoking the transaction again.

//--------------------------------------------------------------------------------------------------

// The following is an example vuser_end procedure
vuser_end()
{
// End each transaction
lr_end_transaction_instance(txnHandle,LR_PASS);

return 0;
}

//--------------------------------------------------------------------------------------------------

The first code line in the "example for running download size monitoring" should read:
lr_start_transaction_instance("TransactionName", txnHandle);

More duh! (Sorry I can't simply delete these comments and start over).

1. The txnHandle is supposed to be long.
2. The txnHandle should be initialized in vuser_init as:
{
txnHandle = lr_start_transaction_instance("TransactionName", 0);
lr_start_transaction_instance(txnHandle);
return 0;
}

So Jay, any comments on my obviously limited knowledge of LoadRunner and your function?
