We have a Network interface discovery where we make these : (Network interface discovery)

perf_counter["\510({#IFNAME})\544",300]
perf_counter["\510({#IFNAME})\388",300]

BUT when there is this interface (as seen in Device Manager and the same in list for net.if.discovery):
Intel(R) 82574L Gigabit Network Connection
the interface name in Performance Monitor is :
Intel[R] 82574L Gigabit Network Connection

therefore for discovered interfaces we get this error:
ZBX_NOTSUPPORTED: Cannot obtain performance information from collector.
because the interface name is with () but the item in perf_counter item needs to be specified with [ ] to be working.
