See number of users connected to a Spring Boot and Tomcat application

Is it possible to get the number of users connected to an application with an off-board Tomcat?

I tried to use netstat -ano to see the process.

Also I tried ps -ef | grep java but it gave me info that I'm not sure is correct.

Several options:

1. Check the number of active sessions in Tomcat Manager:

• Go to tomcat manager page (e.g. http://localhost:8080/manager/html)
• Log in and you will the info regarding number of active sessions

2. Use netstat

netstat -an | grep 8080 | grep ESTABLISHED | wc -l

You could also try to see it in java code - see here
