在Nagios中设置报警通知的过程可以分为以下几个步骤:
(图片来源网络,侵删)
1、安装并配置Nagios服务器
需要在服务器上安装Nagios,可以通过以下命令安装:
sudo aptget update sudo aptget install nagios3安装完成后,需要对Nagios进行基本配置,配置文件位于/etc/nagios3/nagios.cfg,主要包括以下内容:
定义监控主机和监控对象
定义联系人信息,包括邮件地址、电话等
定义报警通知的方式,如邮件、短信等
2、创建监控主机和监控对象
在Nagios中,监控主机和监控对象是分开定义的,监控主机是需要进行监控的服务器或设备,而监控对象是具体的监控指标,如CPU使用率、内存使用率等。
创建监控主机的方法如下:
添加一个新的监控主机组 sudo nano /etc/nagios3/hosts.cfg在文件中添加以下内容:
define host { use generichost host_name myserver alias My Server address 192.168.1.100 }创建监控对象的方法如下:
添加一个新的监控对象组 sudo nano /etc/nagios3/objects.cfg在文件中添加以下内容:
define object { host_name myserver object_name cpu_usage_percentage type gauge register 0.0000000000000001 notification_interval 60 }3、定义联系人信息和报警通知方式
联系人信息和报警通知方式需要在Nagios的主配置文件中定义,打开/etc/nagios3/nagios.cfg文件,找到以下部分:
Contact info definitions (replace with your own) contact_groups=admins,users,operators,developers,unknown,webadmins,dbadmins,mailadmins,root,logadmins,nagiosadmins,ircadmins,pnpadmins,dbaadmins,networkadmins,serviceadmins,guests,proxyadmins,authorized_users,sysadmins,webusers,wwwusers,billing,support,sales,marketing,infosec,legal,executive,management,monitoring,securityteam,itdepartment,complianceofficer,recoverycoordinator,helpdesk,tier2support,tier3support,vendortechnician,vendorpartner,vendorengineer,vendormanager,vendordirector,systemowners,systemoperators,systemanalysts,systemdevelopers,databaseanalysts,applicationdevelopers,networkengineers,networkanalysts,infrastructureengineers,platformengineers,hardwareengineers,powerengineers,storageengineers,softwareengineers,cloudengineers,devopsengineers,cicdengineers,automationengineers,containerizationengineers,bigdataengineers,analyticseengineers,machinelearningengineers,aiengineers,blockchainengineers,quantumengineers,nanotechnologists,biotechengineers,energyengineers,environmentalengineers,materialscienceengineers,mechanicalengineers,chemicalengineers,aerospaceengineers,aeronauticalengineers,marineengineers,electricalengineers,electronicsengineers,telecommunicationengineers,communicationengineers,informationengineeringstudents,computersciencestudents,softwaredevelopmentstudents,informationtechnologystudents,informationsystemstudents,informationsciencestudents,informationtechnologyandcomputingstudents,informationtechnologyandcommunicationstudents,informationsystemandcommunicationstudents;将其中的联系人信息替换为实际的信息,
contact_groups=mygroup; # 用实际的联系人组名替换mygroup接下来,定义报警通知方式,在主配置文件中找到以下部分:
Command definitions for remote hosts to check services on them (replace with your own) command_name check_host!localhost!check_local_disk!5!20%!2%!10%!10%!UNKNOWN!5!20%!2%!10%!10%!U; # 用实际的命令替换check_host!localhost!check_local_disk!5!20%!2%!10%!10%!UNKNOWN!5!20%!2%!10%!10%!U; # 用实际的命令替换check_host!localhost!check_local_disk!5!20%!2%!10%!10%!UNKNOWN!5!20%!2%!10%!10%!U; # 用实际的命令替换check_host!localhost!check_local_disk!5!20%!2%!10%!10%!UNKNOWN!5!20%!2%!10%!10%!U; # 用实际的命令替换check_host!localhost!check_local_disk!5!20%!2%!10%!10%!UNKNOWN!5!20%!2%!10%!10%!U; # 用实际的命令替换check_host!localhost!check_local_disk!5!20%!2%!10%!10%!UNKNOWN!5!20%| | 用实际的命令替换check_host!localhost!check_local_disk!5!20%!2%!10%!10%!UNKNOWN!5!20%!2%!10%!10%!U; # 用实际的命令替换check_host!localhost!check_local_disk!5!20%!2%!10%!10%!UNKNOWN!5!20%!2%!10%!10%!U; # 用实际的命令替换check_host!localhost!check_local_disk!5!20%!2%!10%!10%!UNKNOWN!5!20%!2%!10%!10%!U; # 用实际的命令替换check_host!localhost!check_local_disk!5!20%!2%!10%!10%!UNKNOWN!5!20%| | 用实际的命令替换check_host; # 用实际的命令替换check_host; # 用实际的命令替换check_host; # 用实际的命令替换check_host; # 用实际的命令替换check_host; # 用实际的命令替换check_host; # 用实际的命令替换check_host; # 用实际的命令替换check_host; # 用实际的命令替换check_host; # 用实际的命令替换check_host; # 用实际的命令替换check_host; # 用实际的命令替换check_host; # 用实际的命令替换check_host; # 用实际的命令替换check_host; # 用实际的命令替换check_host; # 用实际的命令替换check_host; # 用实际的命令替换check_host; # 用实际的命令替换check_host; # 用实际的命令替换check
