Upgraded to Zabbix 2.2.2 and have problems with SNMP items

[Jason]

Previously I had a zabbix 2.0.11 server that used a large amount of SNMP to get data.

In particular I probe dell servers to see if a minimum version of the driver software is installed for a given controller number. The details from the item prototype is

SNMPV2

OID .1.3.6.1.4.1.674.10893.1.20.130.1.1.45.{#SNMPINDEX }

If this value does not exist then previously zabbix reported the item as unavailable (desired behaviour) and I knew that the item didn't exist do the firmware was up-to-date.

Now, after the upgrade to 2.2.2 then all the items that were previously reporting as unsupported are now reporting "SNMP error: (noSuchName) There is no such variable name in this MIB."

Is there a way of changing this behaviour to the way it was previously or at least a better way of handling it?

Upgrading the proxies seem to fix that.

However, now all the triggers are saying "item not supported for function"

I'm guessing that is because the item has now gone unsupported... I want for these triggers to only show an alert when the item is supported. There still isn't a trigger to detect for this.

Is there a way of hiding these alerts completely? i.e. not showing them up on the status screen at all?

I'll start a new thread for this as the nature of the question has changed.
