@madhavi gunasekar , After researching, I find in the document of the System Center 2019 Management Pack for JEE Application Servers, it shows monitoring Tomcat 8+:

For the MP that can monitor Tomcat 6, I find the supported SCOM version are 2012 R2, 2016, 2019 is not included:

So if we want monitor Tomcat in SCOM 2019, on my point of view, we can upgrade the Tomcat to 8+. After that, import the first MP to monitor.
Hope it can help.
