I've encountered a situation in which dashboard displayed wrong total number of true triggers.
The problem as I see it is that dashboard's section 'Zabbix status' does not check for trigger dependencies. All my hosts triggers depend on a hosts avaliability via icmp. I tried the sql zabbix's dashboard uses to determine number of true triggers and found that few triggers, (depending on icmpping.nodata() that was true) also had value field == 1.
I suppose it could have happened if "child" trigger was true and then "parent" trigger became true and I finally got a wrong number in true-triggers total. Or it's at least confusing.
