Is service status command continuously monitoring the status?

When I ran 

$ sudo service td-agent status

It's not returning back and the cursor is beeping as a signal as if it's continuously checking the status.

Is it the fact?

I also tried with the following but it's not refreshing as I expected. 

watch -n 10 sudo service td-agent status

Any help will be appreciated ;)

  1. watch should work with systemctl, coloring enabled:

    watch -c "sudo SYSTEMD_COLORS=1 systemctl status td-agent"
