Provide an easy way to find which user is connected to which webtier instance. This would make troubleshooting a lot easier.
Regarding your requirement to have a way to know which user connects to which webtier instance under cluster(load balancer) environment:
1) For which user part, since SM9.60 and SM9.52.P2 we have enhanced this area to store end user ip instead of proxy ip to syslog table, user can acheive the purpose to know which user/client connects to server by configuring web parameter(xff.trusted.proxies) in webtier side, for details you can refer to below steps in helpserver:
2) For which webtier instance part, you can easily achieve it by configuration setting changes in tomcat cluster/load balancer side, there is a "jvmRoute" variable which is one routing identifier and you can use to achieve your purpose.
For detailed usage you can check corresponding documentations.
Thanks and please let me know if you have any further questions or concerns.
