Key points and difficulties:

Point 1. Introduction to Zabbix

Zabbix is an enterprise-level open source distributed monitoring solution, which is written in C language.

Architecture (server and agent), which is continuously maintained and updated by a foreign team, and the software is free to download.

For use, the operation team makes a profit by providing technical support for a fee.

Official website: http://www.zabbix.com

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.

data

Server side: collect the data sent by SNMP and agent, write it to the MySQL database, and then use the

Php+apache is displayed at the front end of web.

Zabbix operating conditions:

Server:

Zabbix Server needs to run in LAMP (Linux+Apache+Mysql+PHP) environment, for hardware

Low requirements

Agent:

At present, the existing agent basically supports common OS in the market, including Linux, HPUX, Solaris, Sun,

Windows et al.

SNMP:

Support all kinds of common network equipment Zabbix functions

Have the functions of common commercial monitoring software (host performance monitoring, network equipment performance monitoring,

Database performance monitoring, FTP and other common protocols monitoring, multiple alarm methods, detailed report chart drawing)

Support automatic discovery of network devices and servers, support distributed, centralized display and management of distributed monitoring

Point, strong expansibility, server provides a general interface, you can develop and improve all kinds of monitoring.

Point two: 1. Advantages and disadvantages

Advantages:

Open source, no software cost input

Server requires low device performance (actual test environment: virtual machine Redhat EL AS5,2GCPU 1G

Memory, monitoring 5 devices, CPU utilization is basically kept below 10%, memory remaining is more than 400m)

Support for multiple Devic

Support for distributed centralized management

Open interface with strong expansibility

When the monitored item is more than one server queue is large, the passive state can be adopted, and the monitored client

Actively download the item to be monitored from the server side and then take the data and upload it to the server side. In this way

The load on the server is relatively small.

Disadvantages:

Without the support of the manufacturer, it is troublesome to solve the problems.

Agent needs to be installed on the monitored host. All the data is stored in the database, and the resulting data is very large.

The bottleneck is mainly in the database.

Focus 3. The monitoring principle of 1.zabbix:

Component description:

1) zabbix server: the core component responsible for receiving report information sent by agent, all configurations and statistics

The data and operation data are organized by it.

2) database storage: dedicated to storing all configuration information, as well as data collected by zabbix

3) GUI interface of web interface:zabbix

4) proxy: optional component, often used in a distributed environment with a large number of monitoring nodes, acting as a server collector

Forwarding the data to server can reduce the pressure on server.

5) agent: deployed on the monitored host, responsible for collecting host local data such as cpu, memory, and data

Database and other data are sent to server or proxy.

Monitoring process:

Agentd needs to be installed on the monitored host and is responsible for collecting data on a regular basis and sending it to the

On the zabbix server side, zabbix server stores the data in the database, and zabbix web stores the data first according to the data

The end carries on the display and drawing. Here, agentd collects data in two modes: active and passive:

Initiative: agent requests server to obtain a list of active monitoring items, and takes the initiative to detect the monitoring items.

Submit the data to server/proxy

Passive: server requests agent to obtain data of monitoring items, and agent returns data.

Client daemon:

This process collects client data, such as cpu load, memory, hard disk usage, and so on.

Zabbix_get

Zabbix tool, a separate command, usually executed on the server or proxy side to get a remote customer

The command of the end information. Usually the user troubleshoots. For example, if I can't get the memory data of the client on the server side, I

You can use zabbix_get to get the content of the client to do troubleshooting.

Zabbix_sender

The zabbix tool, used to send data to server or proxy, is usually used for time-consuming checks.

Many checks are time-consuming, causing zabbix to time out. So after the script has been executed, we use the

Sender actively submits data.

Zabbix_server

The zabbix server keeps the guard process. Zabbix_agentd 、 zabbix_get 、 zabbix_sender 、

The data of zabbix_proxy and zabbix_java_gateway are finally submitted to server.

Remarks: of course, not all data is actively submitted to zabbix_server, and some server takes the initiative to fetch data.

According to.

Zabbix_proxy

Zabbix proxy daemon. The function is similar to server, except that it is just a transit station.

The collected data needs to be submitted / submitted to server. Why use an agent? What does an agent do?

Donovan? As a matter of fact, please continue to follow the zabbix tutorial series of operation and maintenance survival time.

Zabbix_java_gateway

A feature introduced after zabbix2.0. As the name implies: Java gateway, similar to agentd, but only

Used in Java. What needs special attention is that it can only obtain data actively, not passively.

data. Its data will eventually be given to server or proxy.

Focus 4 extension: monitoring architecture of zabbix

In the actual monitoring architecture, zabbix is divided into three architectures according to network environment and monitoring scale:

There are three kinds of server-client, master-node-client and server-proxy-client.

1. Server-client architecture

It is also the simplest structure of zabbix. There is no agent between the monitor computer and the monitored computer.

Data exchange is carried out between zabbix server and zabbix agentd. Suitable for the network is relatively simple, equipment

Less monitoring environment.

2. Server-proxy-client architecture

Proxy is a bridge between server and client, proxy itself does not have a front end, and

It does not store the data itself, but temporarily stores the data sent by agentd, and then submits it to

Server . This architecture is often compared with the master-node-client architecture and is generally applicable across the

Computer room, cross-network medium-sized network architecture monitoring.

3. Master-node-client architecture

This architecture is the most complex monitoring architecture of zabbix, and is suitable for large-scale computers with more equipment and across networks and computer rooms.

Environment. Each node is also a server terminal. Proxy can be connected to the node, or directly.

Get me client. Node has its own configuration file and database, and what it needs to do is to put the configuration information and the number of monitors

According to synchronization to master, master failure or damage to the integrity of the underlying architecture of node.

Focus 5 introduction to Grafana:

Grafana is a visual panel (Dashboard) with beautiful diagrams and layouts.

Full-featured measurement dashboards and graphical editors that support Graphite, zabbix, InfluxDB,

Prometheus and OpenTSDB are used as data sources. In InfluxDB (written in go language, it is an open

Source, distributed, time series, event, measurable and non-externally dependent database) as the underlying database

Grafana main features: flexible and rich graphics options; can mix multiple styles; support for daytime and

Night mode; multiple data sources. three。 Project experiment steps (operation screenshot or operation command) 1.

Check the following three monitoring templates and click the Select button

The monitoring items of this host are displayed in the previous interface, and the graphics of this host can be created according to the monitoring items.

Select the monitoring item, click Select

View the graphics of the monitoring host

But unexpectedly, all the monitoring items about the Mysql database have no graphics, as shown in the figure

After inspection, the problem is shown in the following figure. The key value of the monitoring Mysql server is not used.

The solution is as follows

Set the key value of monitoring failure and open the zabbix_server server, which is also the monitored end.

Log in to the web interface of zabbix to add agent hosts and verify monitoring

Control effect

Add agent.zabbix.com hosts, five after the default graphics, no ftp service graphics, then manually add

Ftp service graphic display

6. Configure and monitor Win2k8dc1 hosts to verify the effect

First configure the network of the windows2008 host

Secondly, use the host to visit the zabbix official website to download the plug-in for monitoring windows2008.

When the download is complete, copy the downloaded plug-in to the test host win2k8dc1 for configuration

C:\ zabbix\ bin\ win64\ zabbix_agentd.exe-c C:\ zabbix\ conf\ zabbix_agentd.win.conf-I # # installation

C:\ zabbix\ bin\ win64\ zabbix_agentd.exe-c C:\ zabbix\ conf\ zabbix_agentd.win.conf-s # # launch

C:\ zabbix\ bin\ win64\ zabbix_agentd.exe-c C:\ zabbix\ conf\ zabbix_agentd.win.conf-d # # Delete

Windows host configuration is complete. Add host win2k8dc1 in the web interface below.

Add is completed. The default figure is 2, which can be added manually. Without too much explanation here, verify that the current drawing is as follows

7. Customize monitoring items, create projects, triggers, graphics, and verify the monitoring effect

The above associated Template OS Linux templates basically cover all system-level monitoring, including the ones we are most concerned about.

Several items: ping, load, cpu utilization, memory, disk, network card traffic, etc. Of course, some triggers have thresholds that can

Can need to be modified according to the situation of the server.

The following is to add a custom server memory usage test item, where a monitoring item is configured as follows: memory usage 70m for warning

Reminder:

1. Modify the client zabbix_agentd.conf configuration file and add the following on the last line:

UserParameter=memory_userd,free-m | grep Mem | awk'{print $3}'

Syntax: UserParameter=key,shell command

Monitoring key value: the memory_userd,key value can be written at will, but when you need to create a monitoring item on the web page later

Specify key value

Shell command or script: free-m | grep Mem | awk'{print $3}'

Note: you can use the zabbix_get-s agent ip address-p 10050-k key name on the zabbix_server side.

You can view the monitoring values of key on the agent side through this command

The specific implementation is as follows: change the configuration file of the agent.zabbix.com host to customize the monitoring items.

[root@agent ~] # vi / usr/local/zabbix/etc/zabbix_agentd.conf
