具有Munin服务的Nagios提供了未知

Question

在Debian Wheezy更新的服务器上，我正在使用以下软件包的backport：

• Nagios：nagios3（3.4.1-5~bpo7 + 1）
• Munin：munin（2.0.25-1~bpo70 + 1）

和nsca（2.9.1-2）将数据从Munin传输到Nagios以处理警报。

Nagios使用以下配置的Munin服务正常工作：

# generic service template definition
define service{
    name                           generic-munin-service ; The 'name' of this service template
    use generic-service
    check_command                  return-unknown!"No Data from passive check"
    active_checks_enabled          0       ; Active service checks are disabled
    passive_checks_enabled          1
    parallelize_check               1
    notifications_enabled           1
    event_handler_enabled           1
    is_volatile                     1
    notification_interval           120
    notification_period             24x7
    notification_options            w,u,c,r
    check_freshness                1
    freshness_threshold            360
    flap_detection_options         n
    max_check_attempts             2
    register                       0   ; DONT REGISTER THIS DEFINITION - ITS NOT A REAL SERVICE, JUST A TEMPLATE!
    ;first_notification_delay      6    ; Delay first notification for false positives (will execute 2 checks : munin sends 1 check every 5 minutes)
}


define service {
    hostgroup_name                munin
    service_description           Disk latency per device :: Average latency for /dev/sda
    use generic-munin-service
    notification_interval         0 ; set > 0 if you want to be renotified
}

define service {
    service_description           Disk latency per device :: Average latency for /dev/sdb
    use generic-munin-service
    notification_interval         0 ; set > 0 if you want to be renotified
}

define service {
    hostgroup_name                munin
    service_description           Disk usage in percent
    use generic-munin-service
    notification_interval         0 ; set > 0 if you want to be renotified
}

define service {
    hostgroup_name                munin
    service_description           Inode usage in percent
    use generic-munin-service
    notification_interval         0 ; set > 0 if you want to be renotified
}

define service {
    hostgroup_name                munin
    service_description           File table usage
    use generic-munin-service
    notification_interval         0 ; set > 0 if you want to be renotified
}

但是，当我添加所有受监控主机上可用的其他服务时，它们将在Nagios中标记为 UNKNOWN ：

define service {
    hostgroup_name                 munin
    service_description            Memory usage
    use generic-munin-service
    notification_interval          0 ; set > 0 if you want to be renotified
}

define service {
    hostgroup_name                 munin
    service_description            CPU usage
    use generic-munin-service
    notification_interval          0 ; set > 0 if you want to be renotified
}

我已经发现，根据munin插件图标题格式，Nagios可能无法理解传入的数据，这就是为什么我将服务器上的软件包更新到Wheezy的backports版本，因为Munin 2.0.7应该清理所有标题。

我还尝试使用更高的调试级别进行调试，日志显示：

[1434122043] SERVICE ALERT: HostIJZI4;Memory usage;UNKNOWN;HARD;2;INCONNU

但我可能需要你的帮助才能走得更远。
