Cisco Threat Grid sample issue

[a ali]

Hello,

I have a threat Grid appliance on my network, and we have an issue as there is no sample appearing on Dashboard from the integrated devise, just I need to know how I can check this issue and troubleshooting steps to solve this issue

Do you have confirmation from the device that it has sent (or attempted to send) samples to the appliance?
