triiger : server sscit02 is unreachacle

When click on trigger (alarms)

when click on show all bar are green
I'm a little surprise by the interpreting graph of SLA. if i understand it will be in red saying that is a problem every day.
Can anybody say what wrong with my configuration.
thank's
S.

PS :
in the same way i have a switch stop for 4 days trigger said
2006.Sep.18 11:28:15 TRUE - 4 days 4 days 100%
2006.Sep.18 11:25:50 FALSE - 2.4 mins 2.4 mins 0.04%
but sla all green

SLA is all green because it it is within acceptable SLA pecentage defined in IT Service configuration screen. You selected Status "Not calculate". It means that SLA won't be calculated for this service.
