I have a jar run from jmeter, for stress.
This jar contains a class that writes to the log via logj4.
If I run the jar from my development environment (like eclipse), it writes to the log file, in the path indicated in the log4j configuration. But if I run this jar from jmeter it doesn't write the log file. It seems to me that jmeter unwrites the log file and only writes to its own console log.
Is this happening due to some own jmeter setting preventing the jar from writing to the log file set in log4j.properties?
JMeter has its own logging configuration which lives under log4j2.xml file (located in "bin" folder of your JMeter installation)
If you need to integrate your .jar logging with JMeter logging subsystem you need to make sure to use SLF4J library
import org.slf4j.LoggerFactory;
import org.slf4j.Logger;
//some other code
private static final Logger log = LoggerFactory.getLogger(YourClass.class);
and add an entry to the JMeter's log4j2.xml file with the desired logging level for your code:
<Logger name="your.package.YourClass" level="debug" />

I am running my jmeter script.Inside one sampler,i have http request in that sampler's JSR223 Postprocess I run the main method from executable jar file(I convert my java code into runnable jar file and imported this jar file in the jmeter Testplan).When running this postprocessor i face the error "last block incomplete in decryption".But when i run this jar file in cmd or when running the java code in eclipse,everything works fine.
I can only think of different code page for "cmd" and "JSR223"
In general relying on the current operating system code page is not recommended, you should explicitly set the encoding while doing encryption/decryption and specify the charset to use (UTF-8 is a good choice)
If you don't have the possibility to amend the code in the "executable .jar" you can set file.encoding property in JMeter's system.properties file or pass it via -D command-line argument
jmeter -Dfile.encoding=UTF-8 ......
If you don't have the possibility to amend JMeter properties as well you can simulate running the "executble .jar" from "cmd" using OS Process Sampler, something like:
I am using following to execute spring and creating logs
java -jar AhMachine-0.0.1-SNAPSHOT.jar > c:\log.txt
but this creates a single log for lifetime.
Is there any way to split this log via commandline or spring boot?
java -jar AhMachine-0.0.1-SNAPSHOT.jar > c:\log.txt will pipe the console output to a file
java -jar -Dlogging-file=c:\log.txt AhMachine-0.0.1-SNAPSHOT.jar will output the internal configurated file appenders to a file
java -jar -Dlogging-file=c:\log.txt -Dlogging.file.max-size=4KB AhMachine-0.0.1-SNAPSHOT.jar will output the internal configurated file appenders to a file will create log.txt files of max 4KB in size, a .gz file is created of the older files
For more complex configuration I would advise using a config-file like spring-logback.xml, you can easily specify the location of that file via the CLI -Dlogging.config=c:/log/config/spring-logback.xml
Not via command line,
this can all be done inside the jar via rolling file appender:

If you cannot access the Jar no matter what see this comment:

I haven't tested it but there should be a rotatelogs.exe process for windows as well.
I am trying to run a JMX test to publish JMS messages to ActiveMQ broker from JMeter. If I check the option to use jndi.properties file as below, it does not specifically ask for the path of the file. I want to know how to configure a JNDI properties file in JMeter. Is there a specific place to add the JNDI properties file or how can I provide the path to it?
According to the JMS Publisher documentation
use jndi.properties. Note that the file must be on the classpath - e.g. by updating the user.classpath JMeter property
So if you put the jndi.properties file somewhere to JMeter Classpath JMeter will pick it up.
Another option is setting user.classpath property and include jndi.properties file location there, it can be done in 2 ways:
Add the next line to user.properties file (lives in JMeter's "bin" folder)
user.classpath=/path/to/your/jndi.properties
Pass the property value via -J command-line argument like:
jmeter -Juser.classpath=/path/to/your/jndi.properties -n -t test.jmx -l result.jtl
See Configuring JMeter and Apache JMeter Properties Customization Guide for more information on fine tuning your JMeter instance(s) via setting and overriding properties.
We have a WAR deployment in a tomcat 7 container which has its log4j2.xml file located under the deployment's WEB-INF/classes folder and, the logj42.xml file is configured with monitorInterval="30".
We want to modify the log4j2.xml to contain a new <Logger> node and we want to do this while the deployment is running (i.e. have the monitorInterval bit of log4j2 pick up the new Logger after 30secs).
When we modify the log4j2.xml file under webapps/{deployent-name}/WEB-INF/classes, no changes take place within the running deployment. We verify this by using jconsole to connect to the tomcat server and look at the org.apache.logging.log4j2 Loggers jmx beans within... but we don't see any new Loggers listed.
Is it possible to actually add a new Logger to a running deployment's log4j2 configuration? And if so, is it just a case of modifying the log4j2.xml file of the deployment under webapps\{deployment-name}\WEB-INF\classes? or would we have to modify the log4j2.xml file in the tomcats' temp\... file? or something else entirely?
I am using Jmeter for performance testing and running our tests via Jenkins build server.
We have Jmeter installed on our jenkins box and I am using an Ant build file to launch the jmx file and create the jtl report; which is then evaluated via the Performance plugin in Jenkins.
My problem is that we only have one instance of Jmeter and as such it only creates one jmeter.log file in the /bin directory.
As we will have multiple jobs calling the one Jmeter installation I don't want it, potentially, writing to the same log.
Is there a way of specifying multiple jmeter.log files per plan/job or amending the location?
Thanks for your suggestions. Using a Jmeter Ant Task and have managed to place the log file into the workspace of the jenkins job by the following:
jmeterlogfile="${basedir}/jmeter.log"
This sits within the JMeter tags within the build file.
Without changing .properties file, running jmeter from Windows cmd, simply navigate to bin folder and pass the argument -j[yourLogFileName.log], if you want log entries in a different log file.
C:\apache-jmeter-2.11\bin>jmeter.bat -j myLog.log
