Agent2 Oracle Plugin should query v$asm_diskgroup_stat instead of v$asm_diskgroup in two files in: Zabbix/[src|https://git.zabbix.com/projects/ZBX/repos/zabbix/browse/src]/[go|https://git.zabbix.com/projects/ZBX/repos/zabbix/browse/src/go]/[plugins|https://git.zabbix.com/projects/ZBX/repos/zabbix/browse/src/go/plugins]/oracle/

handler_asm_diskgroups.go

handler_asm_diskgroups_discovery.go

Querying  v$asm_diskgroup  force Oracle to rescan the disks which is slow and has a laot of overhead for Oracle and system.

Querying  v$asm_diskgroup_stat return the exact same data (both rows and columns) without rescanning disks.

Thanks,
