Summary
This page describes how to consolidate the LoadTest logfiles generated on multiple machines during a LoadTest experiment into a single, consolidated file. The result of combining multiple machines' logfiles is that you can view a consolidated Load Test Monitor and you can display a consolidated Load Test Chart.

Step 1: Gather data sources from multiple machines. Gather the required data from multiple machines. The files needed to for the consolidated report are the Loadtest Logs (*-L.log) and the Loadtest script (*.evl).

Step 2: Batch file processing. Once the log file comments have been removed, create a batch file to process the log files, script files and produce the consolidated files. The consolidated files are then run with the log2g component of eValid to display the complete HTML monitor for the merged log file results. Below is a sample batch file which takes in as arguments, two log files, two script files, the consolidated name for each data source, and the name for the HTML monitor to be produced. The batch file can be modified to increase the number of additional files to be processed.

@echo off

REM This batch file takes 7 arguments:
REM 
REM - Two separate log files run on different machines
REM - Two separate but identical script files run on different macines
REM
REM and merges each file type to consolidate reports. 
REM The consolidated files are then passed to log2g.exe to generate
REM the appropriate HTML monitor and LoadTest Chart.  Syntax:
REM
REM Merge.Files.bat [Log1] [Log2] [Combined Log Name] [Script1]
REM   [Script2] [Combined Script Name] [HTML Monitor Name] 
REM
REM This section searches and removes instances of
REM "#--------------------------------------------NEXT"
REM and merges the Loadtest log files into a user specified
REM consolidated logfile

FIND /V "#--------------------------------------------NEXT" %1 >> %3
FIND /V "#--------------------------------------------NEXT" %2 >> %3

REM This section merges the script files into a user specified
REM consolidated script file

type %4 >> %6
type %5 >> %6

REM This section generates the consolidated HTML Monitor report.
REM log2g.exe takes in the consolidated log file name, consolidated
REM script file name, and the specified HTML monitor name as
REM arguments to  create the HTML monitor.

log2g.exe -log "%3" -script "%6" -monitor "%7"

REM This section generates the LoadTest Chart for the merged files
REM log2g.exe takes in the consolidated log file name and the 
REM consolidated script name to produce the chart.

log2g.exe -log "%3" -readall -load -title "%6" -no-path
