Too much false positives

[RedShift]

Hello all


My zabbix server is reporting too much false positives. Services are reported down while nothing is wrong. I've already modified my triggers to report failure only when there's three consecutive failures ({hostname:nntp.max(#3)}#1), the connectivity of the server (it's on a remote site) is OK and performance is not an issue (and it's only monitoring 16 hosts for a total of 65 items). What else can be wrong? Or is my trigger expression wrong?

Thanks,


Glenn
