monitoring tcp port

[fleon]

hello, we have an sql anywhere database that uses port 7081 and i want to monitor it, so i added a windows server host to zabbix and created a trigger to check it, but the port goes up and down about once each minute, and i want to know if this is zabbix's fault or rather the service has that issue.

i don't see an issue with the service, otherwise i would get tons of calls

sorry, this is the key i added:

net.tcp.service[tcp,,7081]
type: simple check
data type: tried boolean (as it should be), then decimal
latest stable zabbix with debian 7

if i can't find a solution, a workaround would be to create a trigger that tries 3 times one each minute and if it can't find a "1" value then assume failure but i don't know how to do that
