Trigger Help: SNMP OID item error "noSuchName"

[abassillo]

Hi All,

Zabbix newb here.

I am trying to trigger when an item snmpgets "nosuchname" (I am not trying to trigger snmp availability)

I have an APC UPS that has a modular network card. When that network card is not communicating fully with the UPS, I will be able to snmpget some OIDs but not all. I currently have a trigger for when SNMP availability is down completely but I am trying to create a trigger when one specific OID returns a (noSuchName) error to let me know it's in this in-between state. It doesn't seem like I can apply any functions against null keys, I have tried things such as count but the trigger just fails because there is no value for the item. Can anyone advise how to trigger when a specific item's OID in SNMPGET is not retrievable?

The item I am trying to trigger is showing "SNMP error: (noSuchName) There is no such variable name in this MIB."

Thanks!

That error is not an item value, so you cannot build a normal trigger to catch it... But there are "internal actions", which allow notifications, if some or other item turn to "not supported" state.

From description it sounds like an SNMP query type of monitoring, right? So I would expect for data to normally be coming on specific predefined intervals, like once per minute or per 5 minutes, or whatever, right? Then why not just add trigger of nodata() type with double or triple interval?
