Number of DNS queries to GTM

Dear Dev Team,

I would like to know how many number of DNS requests are coming to listeners on GTM?

Currently I see the number of "active connections" on GTM GUI as 30. and on the LTM as 10000.

Could you pls let me know about the below?

1) Is the "active connections" on GTM, 30 are the number of DNS requests?

2) If so, why the number of connections on LTM, 10000 are high compared to GTM?

3) If the "active connections" on GTM are not the DNS requests, how can I determine the number of DNS connections to listener?
