[Reserved] JMeter learning (thirty-one) Access Log Sampler

Premise :

Under \ \ server.xml default tomcat conf, there will be a piece of code:

 <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs" pattern="%h %l %u %t &quot;%r&quot; %s %b" prefix="localhost_access_log." suffix=".txt"/>

Start tomcat \ bin following startup.bat, under tomcat \ logs directory, will generate a similar localhost_access_log.2015-04-21.txt file.

The document recorded in the tomcat log information.

 

Example

1, start Jmeter, add a thread group

2, was added Sampler-Access Log Sampler, is provided below:

3. Add the Listener - View Results Tree

4, run.

 

Remaining issues :

1, tomcat itself is running, it will produce localhost_access_log.2015-04-21.txt log file, but when you run jmeter, given:

java.lang.Error: Problem parsing the log file

Not yet resolved.

 

2, the cluster does not test, do not know if it works.

<! - filter configuration information for cluster environments
<Valve className="org.apache.catalina.ha.tcp.ReplicationValve"
                 filter=".*\.gif|.*\.js|.*\.jpeg|.*\.jpg|.*\.png|.*\.htm|.*\.html|.*\.css|.*\.txt"/>
