[ZBX-4591] Low Level Detection fails when using dynamic indexes where the ifDescr has a double quote. Created: 2012 Jan 26  Updated: 2017 May 30  Resolved: 2012 Feb 12

 Description   

While using low level discovery I used
ifInOctets["index","ifDescr","

{#SNMPVALUE}"]
for the OID and
ifInOctets["{#SNMPVALUE}

"]
for both the key and name.

This generates an item like this:

ifInOctets["index", "ifDescr", "1/2/7, 10/100/Gig Ethernet SFP, "to 7705-1.lnbg GE1/1/7 PathC via CRMT""]

However it's not a valid item because the " isn't escaped so zabbix marks the item as Not_supported. It should generate:

ifInOctets["1/2/7, 10/100/Gig Ethernet SFP, \"to 7705-1.lnbg GE1/1/7 PathC via CRMT\""]

I marked this as major because it totally breaks the ability to use lld on many of our routers.

Let me know if you need more information.

I would be happy to test, however, I don't see the changes in trunk. I downloaded version 25240 and can't find anything relevant in the changelog nor does the issue seem to be solved.

Matthew, you have to wait status Closed and then you can take it from trunk branch.
At the moment you can take it from development branch. See Alexander's comments above.

Successfully tested. Please check small changes in r25276.

Thanks! CLOSED

Fixed in version pre-1.9.10, revision 25286.

Critical bug observed because of this commit:
An item prototype creates a real SNMP item with OID "IF-MIB::ifOutOctets.

{#SNMPINDEX}" instead of OID "IF-MIB::ifOutOctets.2"
I mean the macro {#SNMPINDEX}

doesn't substitute to the real numbers.
Broken in revision 25286.
REOPENED

Sasha, and I see typo in previous comment, actually merged revision is 25286

<Sasha> Many thanks! RESOLVED

<zalex> heh, it was a just luck to hit in this bug so fast . Dev branch tested, works as expected, the bug gone. TESTED.

Processing of macros in SNMP OID has been fixed in r25351 (pre-1.9.10).
