Basic introduction of Zabbix 3.0 [1]

Zabbix

Zabbix introduction to zabbix Zabbix is a highly integrated network monitoring solution that can provide enterprise-level open source distributed monitoring solutions, continuously maintained and updated by a foreign team, the software can be downloaded and used freely, the operation team makes a profit by providing fee-based technical support zabbix is an enterprise-level open source solution based on Web interface, providing distributed system monitoring and network monitoring functions. Zabbix can monitor various network parameters, ensure the safe operation of the server system, and provide a flexible notification mechanism to enable system administrators to quickly locate / solve all kinds of problems. Zabbix is mainly composed of two parts: zabbix server and zabbix agent. Optional zabbix proxy zabbix server can monitor the status of remote servers or networks through SNMP,zabbix agent,fping port monitoring, data collection and other functions. Both Linux and Unix platforms are supported. Only client-side Zabbix functions can be installed on Windows platforms.

① has the functions of common commercial monitoring software (host performance monitoring, network equipment performance monitoring, database, performance monitoring, FTP and other general protocol monitoring, multiple alarm methods, detailed report chart drawing)

② supports auto-discovery of network devices and servers (this can be achieved by configuring auto-discovery server rules)

③ supports automatic discovery (low discovery) key to realize batch monitoring of dynamic monitoring items (need to write scripts)

④ supports distributed, centralized display and management of distributed monitoring points.

⑤ expandable, server provides a general interface (api function), can develop and improve all kinds of monitoring (according to the relevant interfaces to write programs to achieve) easy to write plug-ins, you can customize monitoring items, alarm level settings.

⑥ data collection

Availability and performance testing

Support for snmp (including trapping and polling), IPMI,JMX,SSH,TELNET

Custom detection

Customize the frequency of data collection

Server / agent and client mode

Flexible trigger

You can define very flexible problem thresholds, called triggers, from the reference values of the back-end database

Highly customizable alarm

Send notifications, customizable alarm upgrades, recipients, media types

Notify that useful variables can be used with macro variables

Automatic operations include remote commands

Real-time drawing function

Monitoring items draw the data on the graph in real time.

WEB monitoring capability

ZABBIX can simulate a mouse click on a website and check the return value and response time

Api function

The application of api function can be easily combined with other systems, including the use of mobile phone clients.

Advantages and disadvantages of Zabbix

Advantages

1. Open source, no software cost input

2. Server has low requirements for equipment performance.

3. Support a large number of devices, with a variety of monitoring templates

4. Support distributed centralized management, have automatic discovery function, and realize automatic monitoring.

5. Open interface, strong expansibility, easy to write plug-ins

6. When the monitoring item is more than one server queue is large, the passive state can be adopted, and the monitored client takes the initiative from

7. The server side downloads the item to be monitored and then takes the data and uploads it to the server side. This method puts less load on the server.

8. Api support for easy integration with other systems

Shortcoming

Need to install agent on the monitored host, all the data are stored in the database, the resulting data is very large, the bottleneck is mainly in the database.

Zabbix monitoring principle

Zabbix collects data through the Cramp S mode, and displays and configures it on the web side through the Bamp S mode.

Monitored side: the host collects data by installing agent, and the network equipment collects data by SNMP.

Server side: collect the data sent by SNMP and agent, write it to the database (MySQL,ORACLE, etc.), and then display it in the front end of web through php+apache.

Zabbix operating conditions

Server:Zabbix Server needs to run in LAMP (Linux+Apache+Mysql+PHP) environment (or LNMP) with low hardware requirements

Agent: the existing agent basically supports the common OS in the market, including Linux, HPUX, Solaris, Sun,

Windows

SNMP: supports all kinds of common network devices

SNMP (Simple Network Management Protocol, simple Network Management Protocol)

II. Configuration of Zabbix environment

1. Environmental information

[root@localhost ~] # cat / etc/redhat-release CentOS Linux release 7.2.1511 (Core) [root@localhost ~] # uname-r3.10.0-327.28.3.el7.x86_64

2. Yum installation

The Aliyun yum source already provides zabbix3.0, so we need to use the official yum source. The official Yum source download will be slow.

[root@localhost ~] # rpm-ivh http://mirrors.aliyun.com/zabbix/zabbix/3.0/rhel/7/x86_64/zabbix-release-3.0-1.el7.noarch.rpm

Question: why download the release version of zabbix?

[root@localhost ~] # ls / etc/yum.repos.d/CentOS-Base.repo CentOS-Media.repo epel.repo.rpmnewCentOS-CR.repo CentOS-Sources.repo epel-testing.repoCentOS-Debuginfo.repo CentOS-Vault.repo zabbix.repoCentOS-fasttrack.repo epel.repo

Because downloading this version will generate a zabbix.repo file under yum.repos.d

3. Install related software packages

[root@localhost ~] # yum install zabbix-server zabbix-web zabbix-server-mysql zabbix-web-mysql mariadb-server mariadb- y

Tip: in Centos7, mysql is renamed to mariadb

4. Modify PHP time zone settings

[root@localhost ~] # sed-I's setting # php_value date.timezone Europe/Riga@php_value date.timezone Asia/Shanghai@g' / etc/httpd/conf.d/zabbix.conf III. Database settings

1. Start the database

[root@localhost ~] # systemctl start mariadb

two。 Create zabbix database and users

Mysqlcreate database zabbix character set utf8 collate utf8_bin;grant all on zabbix.* to zabbix@'localhost' identified by '123456 leaves with exit

3. Import data

[root@localhost] # cd / usr/share/doc/zabbix-server-mysql-3.0.4/ [root@localhost zabbix-server-mysql-3.0.4] # lltotal 1836 ChangeLog-rw-r--r-- 1 root root 1158948 Jul-1 root root 98 Jul 22 11:05 AUTHORS-rw-r--r-- 1 root root 687803 Jul 22 11:05 ChangeLog-rw-r--r-- 1 root root 17990 Jul 22 11:06 COPYING-rw-r--r-- 1 root root 1158948 Jul 24 02:59 create.sql.gz-rw-r--r-- 1 root root 52 Jul 22 11:06 NEWS-rw-r--r-- 1 root root 188 Jul 22 11:05 README [root@localhost zabbix-server-mysql-3.0.4] # zcat create.sql.gz | mysql- uzabbix-p123456 zabbix

We use zcat to view the sql.gz package. Basically similar to cat

4. Modify zabbix configuration file

[root@localhost zabbix-server-mysql-3.0.4] # vim / etc/zabbix/zabbix_server.conf DBHost=localhost # Host DBName=zabbix # Database name DBUser=zabbix # Database user DBPassword=123456 # Database password

5. Start zabbix and apache

[root@localhost ~] # systemctl start zabbix-server [root@localhost ~] # systemctl start httpd

6.Web interface installs master

Access address: http://192.168.56.11/zabbix/setup.php

Click Next step to install

First of all, make sure that there is no no. If the time zone is not changed, we will be prompted to make changes.

The account passwords are all set in the configuration file. The default port is 3306.

Give our zabbix a name, which will be displayed in the upper right corner.

Finally, we will show our configuration information so that we can see where there are errors.

Click Finish

Tip: please change your password as soon as you go up

7. Configure the zabbix-agent side

[root@localhost ~] # vim / etc/zabbix/zabbix_agentd.conf Server=127.0.0.1 modifies the IP address (passive mode IP address) ServerActive=127.0.0.1 active mode, and actively reports [root@localhost ~] # systemctl start zabbix-agent to the server

View port number

[root@localhost] # netstat-lntpActive Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 0.0.0 0 Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 3306 0.0 0 0 LISTEN 7806/mysqld tcp 0 0 0. 0 0. 0.0LISTEN 11511/zabbix_agentd tcp * LISTEN 1062/sshd tcp 00 127.0.0.1 LISTEN 11511/zabbix_agentd tcp 25 0.0.0.0 LISTEN 2208/master tcp 00 0.0.0.010 10050 0.0.0.0 00 0.0.0.0 LISTEN 2692/snmpd tcp6 10051 0.0.0.0 LISTEN 11335/zabbix_server tcp 00 127.0.0.1 199 0.0.0.0 00:: 80:: * LISTEN 11408/httpd tcp6 0 0: 22: * LISTEN 1062/sshd tcp6 0 0:: 1:25:: * LISTEN 2208/master tcp6 0 0: 443 : * LISTEN 11408/httpd tcp6 00:: 10050:: * LISTEN 11511/zabbix_agentd tcp6 00: 10051: * LISTEN 11335MB Zabibix _ server IV, Web interface configuration

Find Configuration---- > Hosts to add a monitoring host

After enabling it, if there is an error, we can take a look at zabbix's log.

[root@localhost ~] # ls / var/log/zabbix/zabbix_zabbix_agentd.log zabbix_server.log

When the ZBX turns green, the monitoring is successful. Because we do not configure SNMP, JMX, IPMI, and so on. So I sent the surveillance.

Because we have only one server installed now, there is only one host. We can check the CPU and basic information of this host.

Click Monitoring-Graphs to select the content we want to monitor

We can choose any one to view the information.

For example, let's look at the load of CPU

The sum of the number of processes being processed by CPU and waiting for CPU to process over a period of time. Load Average reflects the usage status of CPU from another perspective.

These monitoring is actually zabbix looking up data in the database and then using jd to draw pictures.

Zabbix performance depends on mysql database

5. Zabbix page security settings

1. Set the default account password

After setting up Chinese

VI. Zabbix menu description

A brief introduction to the menu above Zabbix

Below Doshboard, you can set the graphics you want to set, and add them as follows:

At this point, you can find what you like and open it directly.

Screens is actually an aggregate graph that can put multiple images together. Then put it on the big screen for others to see.

Maps is an architecture diagram.

Status of Zabbix is a status bar.

The first line is whether Server runs [yes] and the following running address

The machine monitored in the second line (enabled / closed / template)

Third line monitoring item (enabled / off / unsupported)

Status of the fourth line trigger (enabled / off / [failed / normal])

Number of current users in line 5 (number of online users)

Line 6 A new value that zabbix can receive per second

The level of alarm

We can set the alarm to ring at the front.

The monitoring list on our home page can be dragged at will

We can also turn it off and set the refresh time
