nagios 监控 cisco 交换机

一、环境：
1.已搭建好nagios4.0.8
2.Centos6.5 x86_64

二、需要有4个监控cisco的脚本
check_snmp_cisco_ifstatus
check_snmp_cisco_loadavg
check_snmp_cisco_memutil
check_snmp_env

三、配置
vim /usr/local/nagios/etc/objects/templates.cfg

definehost{nameetnet-switchusegeneric-hostcheck_period24x7check_interval1retry_interval1/2max_check_attempts2check_commandcheck-host-alivenotification_period24x7notification_interval30notification_optionsd,rcontact_groupsadminsregister0}

vim /usr/local/nagios/etc/objects/commands.cfg

vim /usr/local/nagios/etc/objects/151.3.cfg

添加监控交换机
vim /usr/local/nagios/etc/nagios.cfg

cfg_file=/usr/local/nagios/etc/objects/151.3.cfg

重启nagios
/etc/init.d/nagios restart

四、可能会报错

网上的解决方案
How do I install Net::SNMP perl module ? There are 2 ways of doing this
1) By CPAN (best)
on command line, as root :

[your_host]# perl -MCPAN -e shell
cpan shell -- CPAN exploration and modules installation (v1.76)
ReadLine support enabled
cpan> install Net::SNMP

If it's the first time you run CPAN, it will probably ask you some (simple) questions.
CPAN will also ask you to satisfy some dependencies (Crypt::DES, Digest::MD5, etc..).
2) "By hand"

Get the folowings modules (tar.gz format) on www.cpan.org
- Crypt::DES
- Digest::MD5
- Digest::SHA1
- Digest::HMAC
- Net::SNMP

for each one (you must install Net::SNMP at the end) :
tar zxf <module>.tar.gz
cd <module>
perl Makefile.pl
make test
make install
