nagios 監控配置介紹(二）

#配置服務端監控客戶端

[root@nagios etc]# cd objects/

[root@nagios objects]# vi hosts.cfg

# Define a host for the local machine

define host{

        use                     linux-server

        host_name               1.3-samba

        alias                   1.3-samba

        address                 10.89.1.3

        }

define host{

       use                      linux-server

       host_name                1.2-nagios

       alias                    1.2-nagios

       address                  10.89.1.2

       }

define host{

       use                      linux-server

       host_name                1.34-web-lnmp

       alias                    1.34-web-lnmp

       address                  10.89.1.34

       }

define host{

       use                      linux-server

       host_name                1.34-web

       alias                    1.34-web

       address                  10.89.1.34

       }

# Define an optional hostgroup for Linux machines

define hostgroup{

        hostgroup_name  linux-servers ; The name of the hostgroup

        alias           Linux Servers ; Long name of the group

        members         1.3-samba,1.2-nagios,1.34-web-lnmp,1.34-web

        }

檢查語法，先編輯nagios文件,使出錯信息顯示出來

[root@nagios objects]# vim /etc/init.d/nagios +183

 $NagiosBin -v $NagiosCfgFile > /dev/null 2>&1;   修改為：

 $NagiosBin -v $NagiosCfgFile

保存退出

檢查語法，如果報錯如下：

[root@nagios objects]# /etc/init.d/nagios checkconfig

Checking services...

Error: There are no services defined!

        Checked 0 services.

解決方法：

[root@nagios objects]# vi services.cfg 

define service {

        use                     generic-service

        host_name               1.3-samba

        service_description     Disk Partition

        check_command           check_nrpe!check_disk

} 

再檢查語法

[root@nagios objects]# /etc/init.d/nagios checkconfig

Total Warnings: 1

Total Errors:   0

Things look okay - No serious problems were detected during the pre-flight check

 OK.

[root@nagios objects]# 

如果報下面錯誤：

Error:Service check command 'check_nrpe' specified in service 'Disk Partition' for

 host '10-client01' not defined anywhere!

則編輯commands.cfg 文件：

[root@nagios objects]# vi commands.cfg

再末尾加上

# 'check_nrpe' command definition

define command{

        command_name    check_nrpe

        command_line    $USER1$/check_nrpe -H $HOSTADDRESS$ -c $ARG1$

        }

注意：command_line    $USER1$/check_nrpe -H $HOSTADDRESS$ -c $ARG1$ 實際上就是使用這個命令探測：

[root@nagios objects]#/usr/local/nagios/libexec/check_nrpe -H 10.89.1.3 -c check_disk

保存并退出

再檢查語法

[root@nagios objects]# /etc/init.d/nagios checkconfig

沒有錯誤的情況下：

[root@nagios objects]# /etc/init.d/nagios reload

Running configuration check...done.

Reloading nagios configuration...done

[root@nagios objects]# 

http://10.89.1.2/nagios

如果登錄后提示錯誤：

It appears as though you do not have permission to view information for any of the hosts you requested...

If you believe this is an error, check the HTTP server authentication requirements for accessing this CGI

and check the authorization options in your CGI configuration file.

編輯 cgi.cfg

[root@nagios objects]# cd ../

[root@nagios etc]# vi cgi.cfg

# PHYSICAL HTML PATH

# This is the path where the HTML files for Nagios reside.  This

# value is used to locate the logo p_w_picpaths needed by the statusmap

# and statuswrl CGIs.

physical_html_path=/usr/local/nagios/share

:g/nagiosadmin/s//alvin/g           #替換nagiosadmin 為 alvin，該用戶是我安裝的時候添加的

保存并退出

[root@nagios objects]# /etc/init.d/nagios reload
