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 the Load Scenarios
Record interaction with a load generator. This example was based on NeoLoad.
Mark the start of the target business scenarios.
Design -> Virtual User Profiles -> Style Reader -> Actions -> Style - Seasons - Style - Style Sample - Style Gallery -> First Page -> First request in the page -> Advanced -> Request headers:
Add a new header: "Business-Scenario-Start-Marker" (the exact name is available in BusinessScenario.java). The value of the header should be business scenario type.
Mark the end of the target business scenarios.
Design -> Virtual User Profiles -> Style Reader -> Actions -> Style - Seasons - Style - Style Sample - Style Gallery -> RequestHandler_16 -> First request in page -> Advanced -> Request headers:
Add a new header: "Business-Scenario-Start-Marker" (the exact name is available in BusinessScenario.java). Do Not use an empty value - NeoLoad does not send that or the undertow logging does not log it. Use the same string used to mark the scenario start (the business scenario type).
Save.
Prepare the Target Environment
Configure the Access Log Output
This is necessary to be done once.
Stop the server.
cd /c/ovidiu/bin ./environment.sh stop
Update the application server configuration file <access-log> section (if you copy and paste, open this in edit mode to correctly copy quots):
...
<subsystem xmlns="urn:jboss:domain:undertow:1.1">
...
<server name="default-server" >
...
<host name="default-host" alias="localhost">
...
<access-log pattern=""%I" %h %u [%t] "%r" "%q" %s %b %D %{i,Business-Scenario-Start-Marker} %{i,Business-Scenario-Stop-Marker} %{c,JSESSIONID}"/>
...
</host>
</server>
</subsystem>
...
Start the Environment
On the target environment, reset the application server node:
cd /c/ovidiu/bin ./environment.sh start
The start script will also clean the previous logs.
Run the Test
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:
events < ./access_log.log --input-format-file=./access_log.def events < ./access_log.log --input-format-file=./access_log.def describe
Extract per-scenario statistics:
events < ./access_log.log --input-format-file=./access_log.def business-scenario > business-scenarios.csv
Scatter plot the results.
