Hi Sandeep,
There is a Tomcat agent (no installer) image on the 9.7.1 download page towards the bottom of the list
Introscope Agent Files for Apache Tomcat-No Installer r9.7.1
GEN03135411E.tar
Alternatively you can download the agent installer image
Introscope Agent Installers r9.7.1
GEN02112331E.tar
You can then following the instructiosn in the java Agent Implementation Guide for details on how to configure it.
Thanks
Mike
