Introduction to zabbix

Zabbix is an enterprise-level open source solution based on WEB interface that provides distributed system monitoring and network monitoring capabilities.

Zabbix can monitor various network parameters to ensure the safe operation of the server system, and provides a flexible notification mechanism to enable system administrators to quickly locate / solve various problems.

Zabbix consists of two parts, zabbix server and optional component zabbix agent.

Zabbix server can provide remote server / network status monitoring, data collection and other functions through SNMP,zabbix agent,ping, port monitoring and other methods. It can run on platforms such as Linux,Solaris,HP-UX,AIX,Free BSD,Open BSD,OS X.

Zabbix role components

Zabbix agent: responsible for deploying on the monitored host and transmitting the data of the monitored host to zabbix server

Zabbix server: responsible for receiving information sent by agent, organizing configuration information, statistical configuration information and operation data, etc.

Zabbix database: database for storing all configuration information of zabbix and monitoring data

Zabbix web: zabbix's web interface. Management can manage zabbix configuration and view zabbix monitoring information through zabbix's web interface, which can be deployed on a single server.

Zabbix proxy: used in a distributed environment, zabbix proxy manages the collection of information in this area on behalf of the server, and finally sends it to zabbix server

Zabbix communication mode

Agent: monitoring through a dedicated agent

Ssh/Telnet: communicate through remote control protocol

SNMP: communicates with monitored objects through SNMP protocol. Routers and switches support SNMP, which is actually a kind of agent.

IPMI: monitor through IPMI interface, monitor voltage, temperature, fan, and power supply status through IPMI hardware interface

JMX: monitor JVM virtual machines through (java management extensions Java Management extension) ~

Distributed monitoring system: monitoring data is submitted to zabbix proxy and then to zabbix server

Zabbix working mode active mode: the agent side actively collects information and sends it to the server side tool is the zabbix_sender passive mode: the server side active pull information tool is the zabbix_get experimental environment detection side server 192.168.13.128 detected side agent 192.168.13.1301 Install lamp schema on master [root@server ~] # systemctl stop firewalld.service # # close firewall [root@server ~] # systemctl disable firewalld.service [root@server ~] # setenforce 0firewall # install lamp schema # # [root@server ~] # yum install-y\ httpd\ mariadb-server mariadb\ php\ php-mysql\ # associated database php-gd\ libjpeg*\ php-ldap\ php-odbc\ php-pear\ php-xml\ php-xmlrpc\ Php-mhash [root@server ~] # vim / etc/httpd/conf/httpd.conf 95 ServerName www.yun.com:80 # Line 95 Delete comments, domain customization DirectoryIndex index.html index.php # 164line, add home page support class type index.php [root @ server ~] # vim / etc/php.ini 878 date.timezone = PRC # 878 line, put the previous template of Number deletion Add China time zone PRC [root@server ~] # systemctl start httpd.service # # enable the service [root@server ~] # systemctl start mariadb.service [root@server ~] # netstat-natp | egrep'(3306 | 80)'# View the port number tcp 00 0.0.0.0 systemctl start httpd.service 3306 0.0.0.0 * LISTEN 5087/mysqld tcp6 0 0:: 80: * LISTEN 4807/httpd [root@server ~] # mysql_secure_installation # # initialize the database Enter current password for root (enter for none): # enter Set root password directly here?

Template: recovery operation: {TRIGGER.STATUS}: {TRIGGER.NAME} recovery information: recovery host: {HOST.NAME} recovery IP: {HOST.IP} recovery time: {EVENT.DATE}-{EVENT.TIME} recovery level: {TRIGGER.SEVERITY} recovery information: {TRIGGER.NAME}: {ITEM.VALUE} recovery ID: {EVENT.ID} step 9: click on the blue flag to add, and continuous monitoring will be carried out at this time.

[root@agent yum.repos.d] # systemctl stop sshd # # disable the ssh service on the monitored side

[root@agent yum.repos.d] # systemctl start sshd # # enable the ssh service on the monitored side
