    Description

      According to the specification and documentation changes inĀ ZBXNEXT-6144 new internal metric keys should return "0" or show an error when memory buffer is disabled (ProxyBufferMode=disk):

      1. zabbix[proxy_buffer,buffer,<mode>] - should return the "Proxy memory buffer is disabled" error.
      2. zabbix[proxy_buffer,state,changes] - should return "0".
      3. zabbix[proxy_buffer,state,current] - should return "0" (disk mode).

      Also I assume that in such case these metrics probably should be absent in the zabbix[stats,<ip>,<port>] key, like for other optional processes (connectors in Zabbix server metrics, discovery manager/worker/queue metrics...) when memory buffer is disabled.

      Steps to reproduce:

      1. Build Zabbix components from the dev branch (e6ff77f60bb).
      2. Disable the memory buffer by deleting current parameter line (ProxyBufferMode=hybrid) or by setting its value to "disk".
      3. Create and test new items on the Zabbix proxy host.

      Result:
      1. New items return some hardcoded data:

      2. zabbix[proxy_buffer,buffer,total] returns 16 MB, even if you comment out "ProxyMemoryBufferSize=16M" or set the value to "0".

      2. Internal statistics key also contains data about proxy memory buffer:

      Expected:

      New item keys should behave according to the specification and documentation.
