Hello M.Manna, Yes, probably SESSIONS.ser can give you an idea. Maybe if you want to get more accurate results perhaps you can 1. Do it yourself via JMX [1] 2. Give a try to psi-probe [2], it seems that it has everything that you need Hope it helps, Luis [1] https://stackoverflow.com/questions/19827650/java-monitor-active-web-sessions [2] https://cwiki.apache.org/confluence/display/tomcat/AddOns#AddOns-WebApplications El sáb., 19 oct. 2019 a las 2:51, M.

Session Size Calculation Question
Hello, We are trying to do some calculation for our user session size (or near estimate of it). What we understand is that upon a "Graceful" shutdown, Catalina Host will write out the serializable values of all session into a SESSIONS.ser file in the main servlet's work directory. If this is correct, then the size of the the SESSIONS.ser file (assuming 1 user has logged in) would probably (and approximately) equal to a user's session size? We do understand that not all the info in the serializable session may not be required. However, given that StandardManager does the privileged load based on reading the entire SESSIONS.ser file, we thought it would be a more appropriate way of calculating the session size. Any guidance or help is appreciated, and apologies for making any incorrect assumption. Thanks,
