By default, Control Manager agents re-verify their connection with the Control Manager server every eight hours. Edit a configuration file on the agent machine to modify the frequency.
To change agent connection re-verification frequency:
From the managed product's server, navigate to the Control Manager agent home directory (for example, c:\Program Files\Trend\IMSS\Agent).
Back up Entity.cfg.
Open Entity.cfg using a text editor (for example, Notepad).
Search for the parameter ENTITY_retry_hour and specify an integer value to modify the default verification time.
The ENTITY_retry_hour value is in terms of number of hours. Acceptable values are from 1 to 24 hours.
Save and close Entity.cfg to apply the new verification time.
