在Nagios中如何配置网络服务监控

在Nagios中配置网络服务监控

Nagios是一款开源的网络监控系统，它可以监控服务器、网络设备、应用程序等的运行状态，本文将介绍如何在Nagios中配置网络服务监控。

1、安装Nagios

首先需要在服务器上安装Nagios，以下是在不同操作系统上安装Nagios的方法：

在Ubuntu/Debian系统上安装Nagios：

sudo aptget update sudo aptget install nagios3

在CentOS/RHEL系统上安装Nagios：

sudo yum install epelrelease sudo yum install nagiosserver nagiospluginsstandard

2、配置Nagios

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，以下是一些常用的配置项：

设置Nagios运行的用户和组 nagios_user=nagios nagios_group=nagcmd 设置访问Nagios的用户名和密码 nagios_username=admin nagios_password=your_password 设置邮件通知的参数 email_from=your_email@example.com email_host=smtp.example.com email_use_ssl=yes email_auth_username=your_email@example.com email_auth_password=your_email_password

3、添加主机和服务定义

在Nagios中，需要为要监控的主机和服务定义一个配置文件，配置文件位于/etc/nagios3/objects目录下，以下是一个简单的示例：

创建一个名为myhost.cfg的文件，用于定义主机：

define host { use generichost host_name myhost alias My Host address 192.168.1.100 max_check_attempts 3 check_period 24x7 notification_interval 30m contact_groups admins, nagiosadmins, networkadmins, webadmins, dbadmins, securityadmins, sysadmins, root, nagios, nagcmd, users, nagiosusers, unassigned, localusers, ptsusers, backupoperator, diskadmin, wheel, syncbackup, powerusers, postfixadmin, apacheadmin, webalizeradmin, mailmanadmin, dnsadmin, ftpadmin, newsadmin, ntpadmin, popadmin, proxyadmin, webminadmin, bindadmin, spamadmin, antivirusadmin, snmpadmin, netdumpadmin, securityadmin, oemadmin, ospdadmin, userdbadmin, ldapadmin, sasladmin, mysqldba, oracledba, postgresqldba, db2dba, ircops, jabberadmin, listadmin, webstatsadmin, logfiledba, nagioscoreboardadmin, nagvisadmin, nagiosgrapheradmin, nagiosndoadmin, napalmadmin, openviewadmin, netscreenadmin, qacontactgroup, pnp4nagiosadmin, rrdtooladmin, xinetdadmin, zabbixadmin, splunkadmin, tivoliadmin, netappdba, netappsupportteam, netapptechsupportteam, netappcomplianceteam, netappcomplianceteam2, netappcomplianceteam3, netappcomplianceteam4, netappcomplianceteam5, netappcomplianceteam6, netappcomplianceteam7, netappcomplianceteam8, netappcomplianceteam9, netappcomplianceteam10 }

创建一个名为myservice.cfg的文件，用于定义服务：

define service { use genericservice host_name myhost service_description Ping Test Service for myhost check_command ping!192.168.1.100!50000!25000!50000!PING!50000!25000!50000!EXITVAL!100.0%!200.0%!500.0%!UNKNOWN!5000.0%!80%!10%!120%!240%!360%!480%!600%!720%!840%!960%!PING OK Packet loss = 1%, RTA = 5ms | PING FAILED Packet loss = 6%, RTA = 15ms | PING CRITICAL Packet loss = 15%, RTA = 35ms | PING UNKNOWN Packet loss = 25%, RTA = 55ms | PING DEGRADED Packet loss = 35%, RTA = 75ms | PING RETIRED Packet loss = 45%, RTA = 95ms | PING UNKNOWN Packet loss = 55%, RTA = 115ms | PING CRITICAL Packet loss = 65%, RTA = 135ms | PING FAILED Packet loss = 75%, RTA = 155ms | PING UNKNOWN Packet loss = 85%, RTA = 175ms | PING DEGRADED Packet loss = 95%, RTA = 195ms | PING RETIRED Packet loss = 105%, RTA = 215ms | PING UNKNOWN Packet loss = 115%, RTA = 235ms | PING CRITICAL Packet loss = 125%, RTA = 255ms | PING FAILED Packet loss = 135%, RTA = 275ms | PING UNKNOWN Packet loss = 145%, RTA = 295ms | PING DEGRADED Packet loss = 155%, RTA = 315ms | PING RETIRED Packet loss = 165%, RTA = 335ms | PING UNKNOWN Packet loss = 175%, RTA = 355ms | PING CRITICAL Packet loss = 185%, RTA = 375ms | PING FAILED Packet loss = 195%, RTA = 395ms | PING UNKNOWN Packet loss = 205%, RTA = 415ms | PING DEGRADED Packet loss = 215%, RTA = 435ms | PING RETIRED Packet loss = 225%, RTA = 455ms | PING UNKNOWN Packet loss =
