[SSSD-users]How to notice/check SSSD is currently offline.

I didn't applied debug_level in sssd. so I can't get the status of SSSD from sssd_mydomain.log. Instead, I'm checking if SSSD is offline or not by the following command.

netstat -nap | grep 389 | grep ESTABLISHED | wc -l if it's 0 then SSSD is currently offline.

I wonder this way is right to check if SSSD is offline or not.. Is there any other port related to SSSD offline ? or any command to check SSSD offline ?
