This article explains how to increase session timeout values for Ops Manager.
Ops manager session timeout value set to 15 mins by default. So if you do not have any active action on Ops Manager session for this period, session will get time out.
To update the Ops Manager client session timeout:
Log in to Ops Manager VM using the credentials provided during vm deployment.
Log in to Sudo mode by running the command: sudo -i
By default session timeout value set to 900 seconds. You can change is by adjusting the ClientAliveInterval value in the config file available at /etc/ssh/sshd_config.
If you want to disable the session timeout, set the ClientAliveInterval value as 0.
Restart the sshd service to affect the changes.
service sshd restart
