Sorry for this double post... I don't know why, but yesterday I posted it in the wrong forum. Sorry about that!

Hi there
Since the final release of Zabbix 1.6 is here, I can now finally evaluate Zabbix to use in our company. I think Zabbix is one of the most powerful and easy to use monitoring tool, which is free!
Now I've got two questions to triggers, maybe there is a solution for my problems:
I've set up two graphs: the first one is a simple network-bandwidth graph with a 95th percentile line, the second is a graph which shows the current registred modems of customers.
Now I want to set up two triggers:
for the network graph:
1) Send a alert, when the 95th percentil value is > N
for the modem graph:
2) Send a alert, when the difference between previous and last value is > 10%
*** Edit ***
Okay, RTFM was the right answer for problem... but maybe someone has a better solution, because, if I test the value every 300 seconds, the trigger is for 300 seconds ON and then off -> last and prev value are the same... any ideas?
Can I do this with triggers?
Thanks for helping
