Discovery rule "external check" does not work if item parameter is a macro

    Details

      Description

      When creating a discovery rule inside a template with type "external check" and using a macro like

      {HOST.IP} as a parameter to pass to the specified script in the key, zabbix fails to match the returned JSON.
      Example:
      key is: script.name[{HOST.IP}

      ,param1,param2]

      Template is assigned to host with IP 198.18.0.123.

      zabbix_server.log (Debug:4) says:

      11507:20120302:191438.614 In substitute_key_macros() data:'script.name[

      {HOST.IP},param1,param2]" key in received JSON object' where itemid=22508]

      11507:20120302:191438.708 End of DBlld_process_discovery_rule()

      Zabbix expects the script to return a JSON object with object name "script.name[{HOST.IP}

      ,param1,param2]" where the script would return "script.name[198.18.0.123,param1,param2]".

      That makes macros unusable as a parameter to the script. The script would never know what macro was supplied, just the value of the macro.

      I believe this is a bug.
