nagios插件腳本check_linux_stats.pl 安裝

有的時候監控CPU內存使用率的情況時，nagios自身多帶的插件有一些缺陷。

我們下面使用check_linux_stats.pl這個perl腳本來監控系統運行的一些參數。

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，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#報錯如下

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

還是報錯

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

然后執行安裝

perl Makefile.PL

make

make test#執行該命令可能會報錯，不用管

make install

執行/usr/local/nagios/libexec/check_linux_stats.pl,又報錯：

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.
BEGIN failed--compilation aborted at /usr/local/share/perl5/Sys/Statistics/Linux/Processes.pm line 177.
Compilation failed in require at ./check_linux_stats.pl line 34.
BEGIN failed--compilation aborted at ./check_linux_stats.pl line 34.

解決方法

yum -y  install perl-Time-HiRes

然后執行：
