This document guides you how to check all the agent status in console and keep the status automatically updated at the selected interval? Such as if the agent can be contacted on or Remote Control.
Step by Step:
Open Core Console, Navigate to Configure - Agent status options, set Gather agent status to 'For all visible items', and the Refresh internal to the internal you want.
NOTE: This option is disabled by default, and the refresh interval only applies if the option's box is checked. If you enable this, consider using the default 5 minutes interval or longer to reduce the amount of network traffic.
Now the agents status icon will display to indicate if the agent can be contracted, remote control etc.
