I have fallowed below steps :

Administrative Console

In this procedure, you use the web-based Administrative console to specify the agent parameters string.

Follow these steps:

• Go to the Administrative console.
• Navigate to your application server.
• Expand 

  Java and Process Management

   and click 

  Process definition

   on the Configuration tab.
• Click 

  Java Virtual Machine

   under 

  Additional Properties

  .
• Specify the agent parameters string in the 

  Generic JVM arguments

   field. If you paste in the string, be sure to check whether the string has been truncated.
  
  i have given JVM argument like this : -javaagent:/home/itko/agent/InsightAgent.jar=name=was,url=tcp://abc.com:2009  and copied two jar( InsightAgent and Lisaagent ) files in the home directory. 
  
  
  
  Thanks,
  Bhairava

HI Bhairava

 

Please try the URL like this:

 -javaagent:"C:\Program Files\CA\DevTest\agent\InsightAgent.jar"=url=tcp://localhost:2009,name=IAMCL

Caused by: java.lang.IllegalArgumentException: hostname can't be null

Hi Bhairava,

Looking at the stack trace it looks like you have an invalid argument in the configuration.

Caused by: java.lang.IllegalArgumentException: hostname can't be null

Double-check the configuration.

Hi Bhairava,

I agree with Bradley, check the arguments in the configuration as hostname null is mentioned in logs.

Thanks
