    Ошибка: Assuming that agent dropped connection because of access permiss

    Добрый день! Ситуация такая: необходимо мониторить виртуальную машину (OC Windows Server 2003), которая установлена на физ. хосте на Virtualbox (ОС CentOS 6). Zabbix-сервер установлен на другом физ хосте, имеет белый и внутренний IP. При подключении виртуалки к системе мониторинга в веб-интерфейсе напротив узла сети вижу данную ошибку. Привожу детали:

    Виртуалка имеет 2 сетевых интерфейса - один имеет локальный адрес 10.1.1.35 и работает в режиме Bridged, второй - 10.0.3.15, работает в режиме NAT. В Virtualbox с интерфейса 10.0.3.15 проброшен наружу порт 10050:
    Code:
    Protocol Host IP        Host Port  Guest IP    Guest Port
    TCP       xx.xx.xx.xx  10053      10.0.3.15  10050
    UDP       xx.xx.xx.xx  10053      10.0.3.15  10050
    Использую порт 10053, т.к. на порту 10050 физ. хост уже (успешно) мониторится Zabbix'ом. На фаерволе в CentOS порт 10053 открыт.


    Конфиг агента:

    ############ ADVANCED PARAMETERS #################
    
    ### Option: Alias
    #	Sets an alias for parameter. It can be useful to substitute long and complex parameter name with a smaller and simpler one.
    #	For example, if you wish to retrieve paging file usage in percents from the server,
    #	you may use parameter "perf_counter[\Paging File(_Total)\% Usage]", or you may define an alias by adding the following line to configuration file
    #	Alias = pg_usage:perf_counter[\Paging File(_Total)\% Usage]
    #	After that you can use parameter name "pg_usage" to retrieve the same information.
    #	You can specify as many "Alias" records as you wish.
    #	Aliases cannot be used for parameters defined in "PerfCounter" configuration file records.

    #	Defines new parameter <parameter_name> which is an average value for system performance counter <perf_counter_path> for the specified time period <period> (in seconds).
    #	For example, if you wish to receive average number of processor interrupts per second for last minute, you can define new parameter "interrupts" as following:
    #	PerfCounter = interrupts,"\Processor(0)\Interrupts/sec",60
    #	Please note double quotes around performance counter path.
    #	Samples for calculating average value will be taken every second.
    #	You may run "typeperf -qx" to get list of all performance counters available in Windows.
    #
    # Mandatory: no
    # Range:
    # Default:
    
    ### Option: Include
    #	You may include individual files in the configuration file.
    #

    # Default:
    # Include=
    
    # Include=c:\zabbix\zabbix_agentd.userparams.conf
    
    ####### USER-DEFINED MONITORED PARAMETERS #######
    
    ### Option: UnsafeUserParameters
    #	Allow all characters to be passed in arguments to user-defined parameters.
    #	0 - do not allow

    Команда zabbix_get -s xx.xx.xx.xx -p 10053 -k agent.ping c любым допустимым значением ключа выводит пустую строку.

    Помогите, пожалуйста, найти в чем проблема.

    На интерфейсе 10.0.3.15 (который NAT) должен быть настроен адрес шлюза по умолчанию. Попробуй в конфиге агента в качестве адреса заббикс-сервера указать адрес этого шлюза. Возможно, служба NAT VirtualBox'а, получая запрос от zabbix_get, подменяет айпи сервера отправителя на айпи шлюза.

      turboon, большое спасибо! После замены айпи заббикс-сервера на айпи шлюза все заработало.
