nagios插件腳本check_linux_stats.pl安裝
有的時(shí)候監(jiān)控CPU內(nèi)存使用率的情況時(shí)，nagios自身多帶的插件有一些缺陷。
在新邵等地區(qū)，都構(gòu)建了全面的區(qū)域性戰(zhàn)略布局，加強(qiáng)發(fā)展的系統(tǒng)性、市場(chǎng)前瞻性、產(chǎn)品創(chuàng)新能力，以專注、極致的服務(wù)理念，為客戶提供成都網(wǎng)站設(shè)計(jì)、做網(wǎng)站、成都外貿(mào)網(wǎng)站建設(shè)公司 網(wǎng)站設(shè)計(jì)制作按需求定制網(wǎng)站,公司網(wǎng)站建設(shè),企業(yè)網(wǎng)站建設(shè),高端網(wǎng)站設(shè)計(jì),成都全網(wǎng)營(yíng)銷,外貿(mào)網(wǎng)站制作,新邵網(wǎng)站建設(shè)費(fèi)用合理。
我們下面使用check_linux_stats.pl這個(gè)perl腳本來(lái)監(jiān)控系統(tǒng)運(yùn)行的一些參數(shù)。
我們到https://exchange.nagios.org/directory/Plugins/Operating-Systems/Linux/check_linux_stats/details上下載check_linux_stats.pl插件，把插件放到nagios的libexec的目錄里。
同時(shí)，我們還需要安裝Perl插件，下載地址是http://search.cpan.org/CPAN/authors/id/B/BL/BLOONIX/Sys-Statistics-Linux-0.66.tar.gz
執(zhí)行安裝：
tar -zxvf Sys-Statistics-Linux-0.66.tar.gz
cd Sys-Statistics-Linux-0.66
ls
less INSTALL
perl Makefile.PL#報(bào)錯(cuò)如下
Can't locate ExtUtils/MakeMaker.pm in @INC (@INC contains: /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .) at Makefile.PL line 1.
BEGIN failed--compilation aborted at Makefile.PL line 1.
解決方法
安裝perl-UNIVERSAL-require-0.13-1.el6.rf.noarch.rpm
rpm -ivh perl-UNIVERSAL-require-0.13-1.el6.rf.noarch.rpm
還是報(bào)錯(cuò)
Can't locate ExtUtils/MakeMaker.pm in @INC (@INC contains: /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .) at Makefile.PL line 1.
BEGIN failed--compilation aborted at Makefile.PL line 1.
解決方法
yum install -y perl-devel
然后執(zhí)行安裝
perl Makefile.PL
make
make test#執(zhí)行該命令可能會(huì)報(bào)錯(cuò)，不用管
make install
執(zhí)行/usr/local/nagios/libexec/check_linux_stats.pl,又報(bào)錯(cuò)：
Can't locate Time/HiRes.pm in @INC (@INC contains: /usr/local/nagios/libexec /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .) at /usr/local/share/perl5/Sys/Statistics/Linux/Processes.pm line 177.

Compilation failed in require at ./check_linux_stats.pl line 34.

解決方法
yum -y install perl-Time-HiRes
然后執(zhí)行：
