$ssh = Net::SSH::Expect->new(host => "$server",password => "$passwd",user => "$username",raw_pty => 1, timeout => 2);

$login_output=$ssh->login();
if ( $login_output !~ /Last login:/)
{
     print "Failed to login into the Server : $server\n";
     print $Log ("$now Failed to login into the Server : $server, Check the credentials\n");
}
else
{
    print $Log ("$now Logged into the Server : $server\n");
    
    ## PERFORM UR ACTIVITY .....
    
    print "Database check was successful\n";
    print $Log ("$now DatabasE check was successful\n");
}

print $Log "$now *********[ DATABASE CHECK SCRIPT ENDED ]********\n";

$now never changes. how do you know date and time of each logline?
