Zabbix 5 perf_counter Too many parameters

[syntetix]

Hello!

I have an issue related to perf_counter in Zabbix 5.

Below is an working example
perf_counter["\Processor Information(_Total)\% Processor Utility"]

But, when I try to get CPU utilization per core: perf_counter["\Processor Information(0,0)\% Processor Utility"] I get following error:
ZBX_NOTSUPPORTED: Invalid second parameter.

when I try to solve the ussue by adding seconf comma with time interval: perf_counter["\Processor Information(0,0)\% Processor Utility",30] i get error:
ZBX_NOTSUPPORTED: Too many parameters.

Strange that the same things work in Zabbix 3.

So, could you assist me and tell me where I'm wrong?

Thanks a lot in advance!

I am getting "Too many parameters" on the passwd file check with Zabbix 6.0.
