Condition bases SNMP monitoring

[mca2]

After quite some struggles to get Zabbix running on my FreeBSD 12 server, I'm now configuring Zabbix to monitor various devices. One of them is a SNMP capable router. I want to monitor ICMPloss (packetloss) which works great using the SNMP generic template. But this router is frequently turned of and then ICMPloss gives 100% which pollutes the averages and with the auto scaling of axis, also hides the normally 0 to nothing values in the graph.

So is it possible to monitor (and plot) ICMPloss (and other items) based on the condition the router is running? Eg the SNMP availability item? I did some searching on conditions but got lost, so some examples or concrete references to sections of the manual would be of great help.

The availability of SNMP can be obtained by using internal check zabbix[host,snmp,available]

How to link the data acquisition of one data item to another data item I don't know.
Of course, you can make a dependency in the trigger to reduce unnecessary triggers.

You may create a calculated item, for example:
last(iicmppingloss) * (last(zabbix[host,snmp,available])>0)
All you need is negotiation of update intervals...
