Nagios3 和 Ubuntu 14 已禁用 ping 请求。
localhosts 不断在 GUI nagios 界面中报告其已关闭。
这是安装后在 conf.d 目录中找到的默认“localhost_nagios2.cfg”：
# A simple configuration file for monitoring the local host
# This can serve as an example for configuring other servers;
# Custom services specific to this host are added here, but services
# defined in nagios2-common_services.cfg may also apply.
#
define host{
use generic-host ; Name of host template to use
host_name localhost
alias localhost
address 127.0.0.1
}
# Define a service to check the disk space of the root partition
# on the local machine. Warning if < 20% free, critical if
# < 10% free space on partition.
define service{
use generic-service ; Name of service template to use
host_name localhost
service_description Disk Space
check_command check_all_disks!20%!10%
}
# Define a service to check the number of currently logged in
# users on the local machine. Warning if > 20 users, critical
# if > 50 users.
define service{
use generic-service ; Name of service template to use
host_name localhost
service_description Current Users
check_command check_users!20!50
}
# Define a service to check the number of currently running procs
# on the local machine. Warning if > 250 processes, critical if
# > 400 processes.
define service{
use generic-service ; Name of service template to use
host_name localhost
service_description Total Processes
check_command check_procs!250!400
}
# Define a service to check the load on the local machine.
define service{
use generic-service ; Name of service template to use
host_name localhost
service_description Current Load
check_command check_load!5.0!4.0!3.0!10.0!6.0!4.0
}
这几乎是开箱即用的配置。我修改了通用主机，以便不 ping 任何内容：
# Generic host definition template - This is NOT a real host, just a template!
define host{
name generic-host ; The name of this host template
notifications_enabled 1 ; Host notifications are enabled
event_handler_enabled 1 ; Host event handler is enabled
flap_detection_enabled 1 ; Flap detection is enabled
failure_prediction_enabled 1 ; Failure prediction is enabled
process_perf_data 1 ; Process performance data
retain_status_information 1 ; Retain status information across program restarts
retain_nonstatus_information 1 ; Retain non-status information across program restarts
max_check_attempts 10
notification_interval 0
notification_period 24x7
notification_options d,u,r
contact_groups admins
register 0 ; DONT REGISTER THIS DEFINITION - ITS NOT A REAL HOST, JUST A TEMPLATE!
}
我监控的其他服务器都很好，nagios 没有对它们运行任何 ping 检查。但是，nagios 不会停止抱怨本地主机处于严重状态...在 PING 上：
我已经仔细检查了 Google 提供的内容一个多小时了，但仍无法弄清楚如何关闭此项。
我的问题：这实际上是否已关闭并处于锁定的“关闭”状态，或者是否有另一个我错过的设置来阻止本地主机运行 ping 检查？
谢谢。约翰

你必须使用某物进行主机检查，否则状态永远不会改变。
注意到了吗，虽然你是在 19 日截取的屏幕截图，但上面却显示“上次检查”是在 17 日？
如果您不想使用check_ping，请选择另一个插件进行主机检查。或者让它 ping 本地主机；这样做没有坏处，尽管这似乎没有必要。
另外还有check_dummy，您可以使用它来始终返回UP进行主机检查。
