In standard windows template zabbix i find this "vm.memory.size", what does this doing? For example exist in this template "Average disk read queue length" with key "perf_counter[\234(_Total)\1402]". So why the RAM monitoring in zabbix use some dificult contruction, why not used perf counters, like 4\1406 and others? I cant understand for what this "vm.memory.size"? I try to understand from this https://www.zabbix.com/documentation...ry.size_params but cant.
