Trigger for simple chek icmp ping

[kbaranov]

Hi!


I need a simple check that will ping some ip address for 30 days every 30min, and if all pings for 30 days will return 0 trigger will popup.
The idea was to ckeck activity of OpenVPN clients and delete inactive ones.
Is it possible?

So i've got an item:
Simple check
icmpping[192.168.1.123]

I have already tried this:
sum(/VPN clients check/icmpping[192.168.1.123],30d)=0

But its suitable for "last 30 days".

Any ideas?
