How to use perf_counter items keys with Zabbix Aggregate

[gcavalcante8808]

Hello Folks,

I'm trying to create a zabbix aggregate item to mesure the use of incoming and outgoing Active Directory replication.

Actually, i can extract this data using the perf_counter in the following ways:

perf_counter[\NTDS\DRA Inbound Bytes Total/sec, 300] (Simple way)
or
perf_counter["\NTDS\DRA Inbound Bytes Total/sec", 300] (Quoted)
or
perf_counter[\"\NTDS\DRA Inbound Bytes Total/sec\", 300] (Quoted + skip)
or
perf_counter[\"\\NTDS\\DRA Inbound Bytes Total/sec\", 300] (Fully quotted and skipped)

But now, I want to see a value corresponding to a group of Active Directory Servers; so, I Tried to use grpsum as the following:

grpsum["DF_AD_2008","perf_counter[\"\\DirectoryServices(NTDS)\\DRA Inbound Bytes Total/sec\", 300]","last","0"]

Actually, i tried the other 3 ways to put the perf_counter, but I always got the same error on the server log:

No items for key [perf_counter["\\DirectoryServices(NTDS)\\DRA Inbound Bytes Total/sec", 300]] in group(s) [DF_AD_2008]

Is there any way to use perf_counter on zabbix aggregate items?

Thanks in advance.

PS: My other grpsum items that uses vm.memory, etc are working normally.
