Dynamic indexes double query

[michu162]

Hi.
I'm traing to add item with dynamic index:
ifInOctets["index","ifDescr","xe-0/0/4"]
but zabbix send two queries:

12:39:58.231322 IP db-zabbix18.xxx.44527 > 10.5.1.200.snmp: C=xxx$ GetRequest(31) interfaces.ifTable.ifEntry.ifDescr.510
12:39:58.232434 IP db-zabbix18.xxx.44527 > 10.5.1.200.snmp: C=xxx$ GetRequest(31) interfaces.ifTable.ifEntry.ifInOctets.510
12:40:28.771195 IP db-zabbix18.xxx.30295 > 10.5.1.200.snmp: C=xxx$ GetRequest(31) interfaces.ifTable.ifEntry.ifDescr.510
12:40:28.772190 IP db-zabbix18.xxx.30295 > 10.5.1.200.snmp: C=xxx$ GetRequest(31) interfaces.ifTable.ifEntry.ifInOctets.510
12:40:58.258003 IP db-zabbix18.xxx.35371 > 10.5.1.200.snmp: C=xxx$ GetRequest(31) interfaces.ifTable.ifEntry.ifDescr.510
12:40:58.259004 IP db-zabbix18.xxx.35371 > 10.5.1.200.snmp: C=xxx$ GetRequest(31) interfaces.ifTable.ifEntry.ifInOctets.510

instead of one query when i'm using OID:

12:42:32.078643 IP db-zabbix18.xxx.55015 > 10.5.1.200.snmp: C=xxx$ GetRequest(32) 31.1.1.1.6.510
12:43:02.899917 IP db-zabbix18.xxx.26142 > 10.5.1.200.snmp: C=xxx$ GetRequest(32) 31.1.1.1.6.510
12:43:32.678200 IP db-zabbix18.xxx.49751 > 10.5.1.200.snmp: C=xxx$ GetRequest(32) 31.1.1.1.6.510
12:44:02.499232 IP db-zabbix18.xxx.43107 > 10.5.1.200.snmp: C=xxx$ GetRequest(32) 31.1.1.1.6.510

Is possible to use dynamic indexes without additional queries?
Version Zabbix 1.8.1

The only way to prevent that would be to cache the query for a specified period of time. Otherwise you must do two queries, as the first query determines what the OID of the value you are looking for is, and the second actually queries the OID you want. Check the support system and add a ticket in Zbx-next if one does not already exist (https://support.zabbix.com).

So, how can I configure zabbix or item to cache this queries once a hour?

I don't know how zabbix does things in the SNMP code, but if it is looking things up twice now then you could perhaps write an external program which updates your items via the API. Your external script would query the SNMP device in question and then push the OID into the item. You would then run your script via a cron job or something similar.
