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
计算
安全
数据库
网络和加速
企业服务
define host{
name etnet-switch
use generic-host
check_period 24x7
check_interval 1
retry_interval 1/2
max_check_attempts 2
check_command check-host-alive
notification_period 24x7
notification_interval 30
notification_options d,r
contact_groups admins
register 0
}
vim /usr/local/nagios/etc/objects/commands.cfg
##check cisco

}vim /usr/local/nagios/etc/objects/151.3.cfg
define host{

}
define service {

}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
No output on stdout) stderr: Can't locate Net/SNMP.pm in @INC (@INC contains: /usr/local/lib64/perl5 /usr/local/share/perl5

/usr/local/nagios/libexec/check_snmp_env line 21.
问题1：
perl -MCPAN -e shell
Can't locate CPAN.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 .).
解决：
yum install -y perl-CPAN*
问题2：
No output on stdout) stderr: Can't locate Net/SNMP.pm in @INC (@INC contains: /usr/local/lib64/perl5 /usr/local/share/perl5

/usr/local/nagios/libexec/check_snmp_env line 21.
解决：
perl -MCPAN -e shell
cpan[1]> install Net::SNMP
cpan[2]> quit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
