Create trigger from SNMP Traps

[RobinH]

Hello,

I am trying to create a trigger that should react when a portindex in a switch gets the status linkDown. But I don't really know how to go about it.
According to the example below, it applies to "IF-MIB::ifIndex.2" (Port 2) and "SNMPv2-MIB::snmpTrapOID.0", (Linkstatus) which are the values to be retrieved.

Anyone who knows a good way to fix it?

Hey Robin

a (very) fiddly way to do this would be to use preprocessing steps (both the regular expression & the replace steps) to change this output to a JSON format. Then you could use LLD to get these values in an item.
Maybe someone knows a better way to do this but this might be an option.

I'll be honest, working with traps is way more complicated then with active SNMP monitoring. Is active snmp query an option in your setup?

If not - I can make you a draft for you of how it was setup in my environments back when I worked with them.We relied on Multiple problem generation option in trigger, tag value extraction from snmptrap via macros functions and tag based correlation of closing the Alert.

Hello!

Yes, but only to a certain extent. In this case they don't seem to have MIB files for what I'm after, but I'll see if I can do a thorough snmpwalk, discovered yesterday that I could find more than what their files say.

I also prefer SNMP Active….
