A similar problem. Installed AppMon 2018 April, CentOS 7 and openJDK 8. The agent exits immediately after the start. At the same time, there are no error records in the agent logs, in the server logs, or in the system logs.
P.S. Sorry for my bad english 🙂
Hello @dmitry n.
I could not find in the logs except the below message.
2018-07-24 14:17:08 UTC WARNING [Controller] Connection between controller and agent JavaAplication_Monitoring@localhost.localdomain:27886 closed (null)
Which AppMon version do you have?
Which Java version application is using?
Is your application 32bit or 64bit?
Did you use the 32bit or 64bit library to instrument the agent?
Do you have a same server for the collector and server?
Do you have a trail license?
If I forget to ask something then you can add 🙂
