Install New Relic Agent for WSO2 ESB on Windows Platform

Here is how you would configure new relic APM agent for WSO2 ESB running on windows.

I tested this on WSO2 4.9.0 version on windows 7 and 2012 server.

First few attempts to configure New Relic agent ran into issues like,

Error opening zip file or JAR manifest missing : /newrelic.jar
Error occurred during initialization of VM
agent library failed to init: instrument

and sometimes into this,

Error bootstrapping New Relic agent: java.lang.RuntimeException: java.io.IOException: The system cannot find the path specified
java.lang.RuntimeException: java.io.IOException: The system cannot find the path specified

But after couple of hours of playing around, I figured it was a permission issue on the new relic jar and location. You have to make sure that user that owns wso2 server execution also has access to execute new relic jar.

Alternate solution is to use the new relic directory as a java temp directory and then run the agent from that location.

The following should be added to set CMD_LINE_ARGS line in wso2server.bat file,

-Djava.io.tmpdir="/path/to/wso2/wso2esb-4.9.0/newrelic" -javaagent:" /path/to /wso2/wso2esb-4.9.0/newrelic/newrelic.jar"

Side Note on java.io.tmpdir
The default temporary-file directory is specified by the system property java.io.tmpdir. On UNIX systems the default value of this property is typically "/tmp" or "/var/tmp"; on Microsoft Windows systems it is typically "c:\temp". A different value may be given to this system property when the Java virtual machine is invoked, but programmatic changes to this property are not guaranteed to have any effect upon the the temporary directory used by this method.

Start wso2 server using wso2server.bat, you could see following

com.newrelic INFO: New Relic Agent: Loading configuration file "C:\tools\wso2\wso2esb-4.9.0\newrelic\.\newrelic.yml"
com.newrelic INFO: New Relic Agent: Writing to log file: C:\tools\wso2\wso2esb-4.9.0\newrelic\logs\newrelic_agent.log

Now you can see the application statistics by logging into new relic dashboard https://rpm.newrelic.com
