NO matter where do i put the javaagent, no logs show up. Here is the command using ps -elf |grep javaagent

Where to put the javaagent line in the jsvc launch scripts?

Re: I am using jsvc in unix enviroment to launch apache_tomcat, no matter where i put the -javaagent

Hi,

Could you please try the option listed here

A) Please remove the java agent configurations where ever you have configured and follow the steps listed here

The user under which the JVM runs must have write privileges to the conf and logs directories in the Java Agent home. To achieve this, you can install the agent as the same user that owns the JVM or as an administrator on the host machine. The other contents of the agent directory can be restricted to read only access.

To attach the agent to the JVM, follow these steps:

Determine the PID of the JVM to which you want to attach. For example, on Linux, use:
```
ps -A | grep java
```
On Windows, use:
```
jps -l
```

Run the following command, replacing the placeholders for the path to the tools.jar file in your JDK, path to the AppDynamics Java Agent home directory, and the JVM process ID with values appropriate for your environment:

java -Xbootclasspath/a:<path_to_jdk>/lib/tools.jar -jar /<agent_home>/javaagent.jar <jvm_process_id>

Use the equivalent paths for Windows, including drive letter. The following shows an example with system output included:

[appduser@my_centos6 ~]$ ps -A | grep java
 6780 pts/1    00:00:04 java
[appduser@my_centos6 ~]$ java -Xbootclasspath/a:/usr/java/jdk1.7.0_79/lib/tools.jar -jar /home/appduser/appagent/javaagent.jar 6780
Attaching to VM [6780]
agent path >>>/home/appduser/appagent/javaagent.jar

Thanks
Rajesh

Hi,

In addition to earlier update

It appears that tomcat 6 has a JSVC in it that has a bug not allowing the full command line args including the -javaagent arg.

Could you please provide us what version you are using for JSVC.

Please run following command

./jsvc -version

For more information about the bug

Apache bug tracking the issue

https://issues.apache.org/jira/browse/DAEMON-84

There is a fix in the Apache Commons source repository. For more information:

See the information on the Apache source repository .
Go directly to the the SVN source repository .

may also be able to use a binary build of jsvc .

Thanks

Rajesh

I have the same issue.

i couldn't affect 2 different javaagent parametres because they are using jsvc.

Did you resolved this case ?
