You'll need to create a new service{} definition for each unique service
you wish to check for each host you want to check*. Using your example
above, it looks like you'll need 3 service{} definitions --
	1 checking disk on sda1 (based on your example
service_description)
	1 checking HTTP using check_http
	1 checking SMTP using check_smtp

Templates can help you a lot. You can place all the common directives
like check_interval, retry_interval, etc in a template then reference
that template in each service definition. Your resulting service{}
definitions would only contain those directives that changed and likely
only be something like --

define service{
	name		my-service-template
	max_check_attempts	5
	check_interval	5
	retry_interval	3
	check_period		24x7
	notification_interval	30
	notification_period	24x7
	notification_options	w,c,r
	contact_groups		linux-admins
	register 	0
	}

define service{
	use my-service-template
	host_name linux-server
	service description My HTTP Check
	check_command check_http
}
define service{
	use my-service-template	
	host_name linux-server
	service description My SMTP Check
	check_command check_smtp
}
define service{
	use my-service-template
	host_name linux-server
	service description My Disk Check
	check_command check_disk_sda1 (or whatever it is)
}

The documentation and sample config files can be used as a reference for
templating, etc. The examples above are from memory so any syntax errors
are my own. The documentation should be your definitive reference.

* Note that there are some advanced template tricks that can help in
this regard but for your first start you might want to experiment with
simple definitions to understand the concepts.
