ClusterStorage-236-7-配置Nagios监控

0.配置安装包

[root@manager ~]# yum install -y nagios-server-addons
 

1.配置监控指向文件

这里要让每个被监控节点都指向监控站点，同时重启服务。

[root@servera ~]# vim /etc/nagios/nrpe.cfg

[root@servera ~]# systemctl restart nrpe

[root@serverb ~]# vim /etc/nagios/nrpe.cfg

[root@serverb ~]# systemctl restart nrpe

[root@serverc ~]# vim /etc/nagios/nrpe.cfg

[root@serverc ~]# systemctl restart nrpe

[root@serverd ~]# vim /etc/nagios/nrpe.cfg

[root@serverd ~]# systemctl restart nrpe

 

2.配置集群监控

选中集群中的一个节点，让系统自动识别。

[root@manager ~]# configure-gluster-nagios -c gluster-test -H servera.lab.example.com
Cluster configurations changed

3.修改配置文件

修改集群联络配置文件，增加root进行email监控。

修改集群模板配置文件，增加root为联络人。

修改集群对象请求配置文件，增加提示变量。

[root@manager ~]# vim /etc/nagios/gluster/gluster-contacts.cfg

[root@manager ~]# vim /etc/nagios/gluster/gluster-templates.cfg

[root@manager ~]# vim /etc/nagios/objects/commands.cfg

4.重启服务

重启Nagios监控服务。重启邮件服务。发送测试邮件。

[root@manager ~]# service nagios restart
