That should be $url_id = $url_id->[0];
Since the query in get_url_id_list() returns a single column,
consider using the selectcol_arrayref() method, which elimiates
a level of nesting, and would let you elimiate this statement.

That should be $chk_freq = $config_details->[0][0], and so forth.
You can assign everything at once:
my ($chk_freq, $url_timeout, $url, ...blah...) =
@{$config_details->[0]};
It appears get_config_details will be returning only a single
row. If so, consider using the selectrow_arrayref() method, which
removes a nesting level, so you could say:
my ($chk_freq, $url_timeout, $url, ...blah...) = @$config_details};
