Overview

A HttpEvent contains all the query parameters under a “query” MapProperty.

A HttpEvent contains all the incoming headers under a “incoming-headers” MapProperty.

Business Scenario Measurement Procedure

Record interaction with a load generator. This example was based on NeoLoad.

Prepare the Target Environment

On the target environment, reset the application server node:

cd /c/ovidiu/bin
./environment.sh stop
./environment.sh start

The start script will also clean the previous logs.

Shut Down and Collect Data

cd /c/ovidiu
./bin/environment.sh stop

All log data is collected and zipped under /c/ovidiu/data/load-data-yy-mm-dd-hh-mm-ss...zip

Download the test data locally via the QLB-APP02-Redirected-Folder on NOMBP2.

Unzip it in its own separated directory.

The data export script keeps the access log as “access_log.log” and places the definition of the access log fields in access_log.def.

Data Processing

Do initial parsing:

esa < ./access_log.log --input-format-file=./access_log.def 

esa < ./access_log.log --input-format-file=./access_log.def  describe

Extract per-scenario statistics:

esa < ./access_log.log --input-format-file=./access_log.def perf > business-scenarios.csv

Scatter plot the results.
