#注*:
1.以上service.cfg中添加了對(duì)磁盤(pán)分區(qū)、Load、Mem、Swap、磁盤(pán)io的監(jiān)控
2.以上hots.cfg及service的內(nèi)容的詳細(xì)解釋見(jiàn)附錄八
若此時(shí)執(zhí)行如下檢查nagios語(yǔ)法命令:
檢查語(yǔ)法:

記得reload nagios 命令為:/etc/init.d/nagios reload
增加從nagios服務(wù)器端發(fā)起的監(jiān)控:如url地址,端口監(jiān)控
1.添加要監(jiān)控的服務(wù)配置到service.cfg
########check url
#check_weburl (http://blog.etiantian.org) 197-etiantian-1-1
define service{
use generic-service

#請(qǐng)注意看以上監(jiān)控URL 的不同

檢查語(yǔ)法:

根據(jù)錯(cuò)誤可以知道,是check_weburl 插件沒(méi)有定義導(dǎo)致。
、需要在commands.cfg 中加入check_weburl 的插件配置
# 'check_weburl' command definition
define command{
command_name check_weburl
command_line $USER1$/check_http $ARG1$ -w 10 -c 30
}
注意還要添加本地監(jiān)控的插件:
# 'check_mem' command definition
define command{
command_name check_mem
command_line $USER1$/check_mem -w $ARG1$ -c $ARG2$
}
# 'check_load' command definition
define command{
command_name check_load
command_line $USER1$/check_load -w $ARG1$ -c $ARG2$
#command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -c $ARG1$
}
# 'check_disk' command definition
define command{
command_name check_disk
command_line $USER1$/check_disk -w $ARG1$ -c $ARG2$ -p $ARG3$
}
注意:以上三個(gè)插件命令沒(méi)加也是正常的,這點(diǎn)有空偶在細(xì)看看。
如果是測(cè)試,注意在nagios 服務(wù)器端的/etc/hosts 下加
192.168.1.106 blog.etiantian.org
192.168.1.107 www.etiantian.org

使配置文件生效命令/etc/init.d/nagios reload
