nagios監控配置錯誤匯總

1.check_iftraffic監控網卡流量的配置及錯誤解決辦法

服務端：

添加以下內容：

vim /usr/local/nagios/etc/objects/commands.cfg

#check iftraffic
define command{
        command_name    check_iftraffic
        command_line    $USER1$/check_iftraffic -H $HOSTADDRESS$ -i $ARG1$ -w $ARG2$ -c $ARG3$ -b $ARG4$ -u $ARG5$
}

vim /usr/local/nagios/etc/objects/62xxx.cfg

define service{
        use                             local-service
        host_name                       62xxx
        service_description             網卡流量
        check_command                   check_nrpe!check_iftraffic!"eth0"!50!100!100!m
        notifications_enabled           0
}

監控客戶端：

vim /usr/local/nagios/etc/nrpe.cfg

command[check_iftraffic]=/usr/local/nagios/libexec/check_iftraffic_nrpe.pl -i eth0 -w 50 -c 100 -b 100 -u m

重啟服務后，nagios監控頁面提示UNKNOWN,NRPE: Unable to read output
解決辦法：在監控客戶端執行  /usr/local/nagios/libexec/check_iftraffic_nrpe.pl -i eth0 -w 50 -c 100 -b 100 -u m 

然后會在 /tmp 下面 生成一個文件 ls /tmp/ traffic_ifeth0 修改traffic_ifeth0的所屬權限 chown nagios.nagios /tmp/traffic_ifeth0 -R

這樣問題就OK了！

2.nagios錯誤日志里面 tailf /var/log/message提示

。。。。。。等等吧

這個錯誤是因為nagios多進程引起的，你可以ps -ef | grep nagios 發現有多個進程，把他們全部殺掉，然后重啟 /etc/init.d/nagios start ，問題就OK了！

nagios啟用通知提示錯誤：“ 無法打開要更新的命令文件，外部命令文件或目錄權限不對，參考FAQ設置正確的權限”
