Thank you for your reply. I got a chance to read through the thread you pointed to. However it does seem to be related to my problem. The thread was talking about inventory of static configuration. I am looking for the status of gateways, when status is shown on SmartConsole with white cross inside a red circle instead of white check mark inside a green circle. If you hover your cursor over the circle, a popup window would show you what problem is. Things like "IPS:Expired" (shown in the screenshot in my original post),"Connection with 'gateway-a' is lost". I wonder how SmartConsole gets this information dynamically, poll the gateways or gateways are sending snmp periodically.
