How to properly monitor rta and packet lost

Help
1

For a non managed and remote device, I need:
1 Create an rta and packet loss graphic (basic ping info).
2 Trigger an alert / notification when reaching some rta or packet loss value.

I found two ways to do (and triyed both):
1_Enable nagios services , and create a ping check service (check_ping) for localhost with remote ip destination.
PRO:It is working ok , I can trigger the alarm and receive notifications.
CONS: There is no graph. (is it possible to build graph from service?).

2_ Create a host using remote ip, with no snmp check.
After creating device, there are two graph with following comments.
a)_ping response. (without packet loss info)
c) performance. (it is colored , includes rta and packet loss but not values info).

Then , when trying to create an alert rule found this:
macro.packet_loss_5m rule.
How should I use this to set my trigger ?

Ok , thats all … hope you can help how to accomplish my goal.

Sorry … I found those graphics!!!
I will take option1.
After reading and looking for more info , I founded that:
./check-services.php -d provides info about nagios plugins, there you can see where are rrd files generated.
After seeing that , found that , on webinterface you can see graphics generated from those rrds at:
{device} > services > detail.
