1. Zabbix operating architecture

Zabbix is an enterprise-class distributed open source monitoring solution. It can monitor the health of various servers, the stability of the network and the reliability of various application systems. When an exception occurs in monitoring, Zabbix can configure an alarm mechanism based on email, SMS, Wechat and other alarm mechanisms for any event through a flexible alarm policy. All of this can be configured and operated through the web interface provided by Zabbix, and the web-based front-end page also provides excellent reporting and data visualization capabilities. These functions and features make it very easy for our operation and maintenance personnel to build a powerful operation and maintenance monitoring and management platform.

The operating architecture of Zabbix is as follows:

As you can see from the running architecture diagram above, Zabbix is mainly composed of several components, which are as follows:

1 、 Zabbix Server

Zabbix Server is the core component of Zabbix and the core memory of all configuration information, statistics and operation data. It is mainly responsible for receiving reports and information sent by the client. At the same time, all configuration, statistics and configuration operation data are organized by it.

2 、 Zabbix Database Storage

It is mainly used to store data, and all configuration information and data collected by Zabbix are stored in the database. You can use MySQL, oracle, SQLite, and so on.

3. Zabbix Web interface

This is the GUI interface provided by Zabbix and usually (but not necessarily) runs on the same physical machine as Zabbix Server.

4. Zabbix Proxy proxy server

This is an optional component and is often used in distributed monitoring environments. The agent Server can collect new energy and availability data for Zabbix and send them to the Zabbix Server.

5. Zabbix Agent monitoring agent

Zabbix Agent is deployed on the monitored host, can actively monitor local resources and applications, and is responsible for collecting data and sending it to Zabbix Server or Zabbix Proxy.

II. Zabbix monitoring terminology

In the Zabbix monitoring system, there are some common terms, the following is a brief introduction.

1. Host (host)

Represents a server or network device to be monitored, which can be specified by IP or hostname.

2. Host group (host group)

Logical group of hosts: it contains hosts and templates, but there is no direct relationship between hosts and templates within the same host group; host groups are usually used when assigning monitoring permissions to users or user groups.

3. Monitoring items (item)

Represents a specific object for monitoring, such as monitoring the CPU load of the server, disk space, etc. Item is the core of data collection in Zabbix. Relative to a monitoring object, each item is identified by "key".

4. Trigger (trigger)

In fact, it is a monitoring threshold expression, which is used to evaluate whether the data received by a monitoring object is within a reasonable range; if the received data is greater than the threshold, the state of the trigger will change from "OK" to "Problem", and to "OK" when the received data is lower than the threshold.

5. Application set (Applications)

A logical collection of monitoring items.

6. Action (action)

Refers to a pre-defined method of handling problems that occur in monitoring, such as sending notifications, when actions are performed, how often they are performed, and so on.

7. Type of alarm medium (media)

Indicates the means of sending notification and the way of alarm notification, such as Email, Jabber or SMS, etc.

8. Template (template)

A set of implementations that can be applied to one or more hosts. A template usually contains application sets, monitoring items, triggers, graphics, aggregation graphics, auto-discovery rules, web scenarios, and so on; templates can be linked directly to a host.

Template is a difficulty and key point in learning zabbix. In order to achieve batch and automatic monitoring, monitoring items with the same characteristics are usually collected into the template and then directly referenced in the host to achieve rapid monitoring and deployment.

Deploy the Zabbix monitoring platform

The deployment of Zabbix's monitoring platform is relatively simple, as long as the LNMP or LAMP environment is ready.

I will start the configuration here by deploying the LNMP environment.

Note: I deploy all the services on the same server here, which is only a simple monitoring architecture, and zabbix proxy is not deployed.

6. Client accesses the nginx agent to configure zabbix

Just visit the IP/zabbix of the Nignx server, which automatically jumps to the following page:

The error shown above is probably because the configuration item of php does not meet its requirements:

[root@zabbix /] # sed-I 's/post_max_size = 8M/post_max_size = 16m etc/php.ini g' / etc/php.ini [root@zabbix /] # sed-I 's/max_execution_time = 30/max_execution_time = 300 s/max_input_time g' / etc/php.ini [root@zabbix /] # sed-I 's/max_input_time = 60/max_input_time = 300pm g' / etc/php.ini [root@zabbix /] # sed-I's / Date.timezone = / date.timezone = Asia\ / Shanghai/g' / etc/php.ini [root@zabbix /] # sed-I's Gracefully shutting down php-fpm restart service Gracefully shutting down php-fpm.

Another error was reported, indicating that the configuration file could not be created. Let's manually download the configuration file and upload it to the specified directory, then click download.

[root@zabbix /] # ls / usr/local/nginx/html/zabbix/conf/zabbix.conf.php/usr/local/nginx/html/zabbix/conf/zabbix.conf.php

Enter the zabbix username and password to log in (default username: admin, password: zabbix):
