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

how I can confirm this point on Cisco ESA,

we made the integration between ESA and TG but still did not see any sample on TG and after checking the ESA service user on TG I found it active,

>From the ESA gui, make sure your AMP engine logs are enabled and that they're set to Information or higher. Go to System Administration/Log subscriptions, to check that.
Then login to the ESA cli, and grep or tail the AMP log for "File uploaded"

ok thanks for your support but tail AMP will allow me to see if files needs more analysis or is not needed , 

is there any debug to check the connection or integration between ESA end threat Grid 

It will also tell.you if it uploaded it or attempted to. You can get more detail if you put it in debug mode. I suspect you may have to get TAC involved.

hello Ken,

after checking the logs from ESA, I see these messages
