談論一個關於nagios的問題
我話了幾天的時間把整體框架配置好了，但是在配具體的檢測的時間出問題，一直提示我說我的command有問題，可是我就沒有修改這個東西啊，我把我的思路說一下
我是用了了這個自帶的templates裡面的模板，用了裡面generic-contact，generic-host，linux-server，generic-service，local-service。
我的contacts.cfg裡面是這樣寫的 define contact{
contact_name nagios ; Short name of user
use generic-contact ; 引用了模板裡面的generic-contact
alias Nagios ; Full name of user
email 305838894@qq.com ; <<***** CHANGE THIS TO YOUR EMAIL ADDRESS ******
}hosts.cfg是這樣寫的 define host{
use linux-server
host_name test
alias gaofeng-test
address 192.168.39.73
}service是這樣寫的 define service{
use local-service
host_name test
service_description ping
check_command check_ping!100.0,20%!500.0,60%
}其他的都沒修改，然後我驗證就一直提示

Check your configuration file(s) to ensure that they contain valid
directives and data defintions. If you are upgrading from a previous
version of Nagios, you should be aware that some variables/definitions
may have been removed or modified in this version. Make sure to read
the HTML documentation regarding the config files, as well as the
'Whats New' section to find out what has changed.
我在補充下引用到幾個模塊的代碼define contact{

把commands.cfg的第56行後面的一段貼出來看下

define host{
use linux-server
host_name test
alias gaofeng-test
address 192.168.39.73
check_command check-host-alive
}
host.cfg下面加一行 check_command check-host-alive 試試
《解決方案》
我的host文件use了linux-server，而linux-server是我引用模板的，模板裡面是有對host定義的代碼如下define host{
name linux-server ; The name of this host template
use generic-host ; This template inherits other values from the generic-host template
check_period 24x7 ; By default, Linux hosts are checked round the clock
check_interval 5 ; Actively check the host every 5 minutes
retry_interval 1 ; Schedule host check retries at 1 minute intervals
max_check_attempts 10 ; Check each Linux host 10 times (max)
check_command check-host-alive ; Default command to check Linux hosts
notification_period workhours ; Linux admins hate to be woken up, so we only notify during the day
; Note that the notification_period variable is being overridden from
; the value that is inherited from the generic-host template!
notification_interval 120 ; Resend notifications every 2 hours
notification_options d,u,r ; Only send notifications for specific host states
contact_groups admins ; Notifications get sent to the admins by default
register 0 ; DONT REGISTER THIS DEFINITION - ITS NOT A REAL HOST, JUST A TEMPLATE!

你仔細檢查一下，就是那幾個配置文件的問題，nagios很嚴格 一個空格都不行
《解決方案》
你看看你的commands.cfg里是不是定義了兩個check-host-alive。

找到原因了 謝謝你的回答啊回復 6# deweiku
