/etc/init.d/nagios restart 正常

瀏覽器打開http://120.132.xx.xx:8080/nagios/ 查看， 正常

5.配置nsca

在2.14上起nsca daemon服務(wù)，在100.6通過send_nsca傳送到2.14(120.132.xx.xx)統(tǒng)一進(jìn)行前端頁(yè)面展示管理。

(1)編譯nsca

wget http://nchc.dl.sourceforge.net/sourceforge/nagios/nsca-2.7.2.tar.gz

tar -zxvf nsca-2.7.2.tar.gz

cd nsca-2.7.2

./configure make all

(2)nsca2.14服務(wù)端配置(之前已配置好)

cp sample-config/nsca.cfg /etc/nagios/

cp src/nsca /usr/sbin/

配置password

vi /etc/nagios/nsca.cfg

password=139com

開啟nsca程序

/usr/sbin/nsca -c /etc/nagios/nsca.cfg –daemon

vi /usr/local/nagios/etc/nagios.cfg

check_external_commands=1

accept_passive_service_checks=1

accept_passive_host_checks=1

(3)100.6nsca客服端配置

cp sample-config/send_nsca.cfg /etc/nagios/

cp src/send_nsca /usr/bin/

配置password

vi /etc/nagios/send_nsca.cfg

password=139com

vi /usr/local/nagios/etc/nagios.cfg

enable_notifications=0

obsess_over_services=1

ocsp_command=submit_check_result

obsess_over_hosts=1

ochp_command=submit_host_result

cat submit_check_result

#!/bin/sh

return_code=-1

case “$3″ in

OK)

return_code=0

;;

WARNING)

return_code=1

;;

CRITICAL)

return_code=2

;;

return_code=-1

;;

esac

/usr/bin/printf “%st%st%st%sn” “$1″ “$2″ “$return_code” “$4″ | /usr/bin/send_nsca -H 120.132.xx.xx -p 15667 -c /etc/nagios/send_nsca.cfg

cat submit_host_result

#!/bin/sh

(3)測(cè)試

echo “192.168.100.8;TEST_NSCA;2;hahajusttest” | /usr/bin/send_nsca -H 120.132.xx.xx-p 15667 -to 10 -d “;” -c /etc/nagios/send_nsca.cfg

1 data packet(s) sent to host successfully.
