目前有两种不同的 observium 版本。

1、Observium 社区版本是一个在 QPL 开源容许证下的免费工具，这个版本是对付较小支配的最好办理方案。
该版本每6个月进行一次安全性更新。

2、第2个版本是 Observium 专业版，该版本采取基于 SVN 的发布机制。
会得到逐日安全性更新。
该工具适用于做事供应商和企业级支配

CentOS7下支配开源网络监控工具Observium

下面先容CentOS7下支配开源网络管理和监控工具Observium

环境解释:

1、CentOS7.9 VM虚拟机192.168.31.84支配Observium，作为做事端

2、CentOS7.9 VM虚拟机192.168.31.121监控主机，作为Observium的被监控设备

详细支配步骤如下1、根本环境准备1）关闭SELINUX

setenforce0sed-i's/^SELINUX=.$/SELINUX=disabled/'/etc/selinux/config

2）yum源配置

wget-O/etc/yum.repos.d/CentOS-Base.repohttps://mirrors.aliyun.com/repo/Centos-7.reposed-i-e'/mirrors.cloud.aliyuncs.com/d'-e'/mirrors.aliyuncs.com/d'/etc/yum.repos.d/CentOS-Base.repowget-O/etc/yum.repos.d/epel.repohttp://mirrors.aliyun.com/repo/epel-7.repo

添加opennms-repo和remi源

yum-yinstallhttp://yum.opennms.org/repofiles/opennms-repo-stable-rhel7.noarch.rpmyum-yinstallhttp://rpms.remirepo.net/enterprise/remi-release-7.rpm

启用remi-php72源

yuminstallyum-utilsyum-config-manager--enableremi-php72

yum安装Observium所需组件httpd,php72,net-snmp,fping,mariadb-server,rrdtool,ipmitool等等

yuminstallwget.x86_64httpd.x86_64php.x86_64php-opcache.x86_64php-mysql.x86_64php-gd.x86_64\php-posixphp-pear.noarchcronie.x86_64net-snmp.x86_64net-snmp-utils.x86_64\fping.x86_64mariadb-server.x86_64mariadb.x86_64MySQL-python.x86_64rrdtool.x86_64\subversion.x86_64jwhois.x86_64ipmitool.x86_64graphviz.x86_64ImageMagick.x86_64\php-sodium.x86_64

2、下载observium社区版本最新安装包并解压

下载地址

http://www.observium.org/observium-community-latest.tar.gz

创建/opt/observium目录，并将社区版本安装包解压到此路径

mkdir-p/opt/observium&&cd/opttar-zxfobservium-community-latest.tar.gz

3、MariaDB数据库设置1）MariaDB数据库做事启动，密码初始化

systemctlenablemariadbsystemctlstartmariadb/usr/bin/mysqladmin-urootpassword'MySQL@2021'2）创建observium数据库，并设置observium库的账号与密码

mysql-uroot-pMySQL@2021CREATEDATABASEobserviumDEFAULTCHARACTERSETutf8COLLATEutf8_general_ci;GRANTALLPRIVILEGESONobservium.TO'observium'@'localhost'IDENTIFIEDBY'observium@2021';exit;

3）修正config.php中数据库连接参数

cpconfig.php.defaultconfig.phpviconfig.php修正数据库的账户与密码为上面设置的mariadb的账户与密码$config['db_user']='observium';$config['db_pass']='observium@2021';

4)Insert MySQL Schema

./discovery.php-u

4、在config.php中添加fping工具配置

whichfping/usr/sbin/fpingviconfig.php$config['fping']="/usr/sbin/fping";

5、rrd及httpd做事干系配置1）Create the rrd directory to store RRDs in:

cd/opt/observiummkdirrrdchownapache:apacherrd2）httpd做事配置文件添加与修正

vi/etc/httpd/conf.d/observium.conf<VirtualHost>DocumentRoot/opt/observium/html/ServerNameobservium.domain.comCustomLog/opt/observium/logs/access_logcombinedErrorLog/opt/observium/logs/error_log<Directory"/opt/observium/html/">AllowOverrideAllOptionsFollowSymLinksMultiViewsRequireallgranted</Directory></VirtualHost>3）Create logs directory for apache

mkdir/opt/observium/logschownapache:apache/opt/observium/logs

6、设置observium crond定时任务脚本

vi/etc/cron.d/observium#Runacompletediscoveryofalldevicesonceevery6hours33/6root/opt/observium/discovery.php-hall>>/dev/null2>&1#Runautomateddiscoveryofnewlyaddeddevicesevery5minutes/5root/opt/observium/discovery.php-hnew>>/dev/null2>&1#Runmultithreadedpollerwrapperevery1minutes/1root/opt/observium/poller-wrapper.py>>/dev/null2>&1#Runhousekeepingscriptdailyforsyslog,eventlogandalertlog135root/opt/observium/housekeeping.php-ysel#Runhousekeepingscriptdailyforrrds,ports,orphanedentriesinthedatabaseandperformancedata474root/opt/observium/housekeeping.php-yrptbsystemctlreloadcrond

7、web管理员用户添加并开启httpd做事

./adduser.phpadminadmin202110

systemctlenablehttpdsystemctlstarthttpdfirewall-cmd--permanent--zone=public--add-service=httpfirewall-cmd--reload

8、监控主机snmpd做事安装与配置

监控主机上安装并配置snmpd做事

yuminstallnet-snmpnet-snmp-utilssystemctlenablesnmpdvi/etc/snmp/snmpd.conf1)OID修正

原来viewsystemviewincluded.1.3.6.1.2.1.1修正为viewsystemviewincluded.1.3.6.1.2.12）系统位置信息修正

syslocationUnknown(edit/etc/snmp/snmpd.conf)#syslocationUnknown(edit/etc/snmp/snmpd.conf)syslocationHangZhou,Zhejiang,Chinacat/etc/snmp/snmpd.conf|grepsystemviewcat/etc/snmp/snmpd.conf|grepsyslocation

systemctlstartsnmpdnetstat-anp|grep161firewall-cmd--permanent--zone=public--add-service=snmpfirewall-cmd--reload

9、登录web界面，并添加监控设备

(图片可放大查看)

当然你可也可往后台用命令添加

./add_device.php<hostname><community>v2cDoaninitialdiscoveryandpollingruntopopulatethedataforthenewdevice:

拉取设备数据

./discovery.php-hall./poller.php-hall

监控效果展示

10、syslog日志监控功能启用

config.php末了行加入

//EnableSyslog$config['enable_syslog']=1;
