node.js

Features:

Automatic discovery of Node.js processes managed through PM2.

Report Nodes.js process status, CPU usage, memory usage and whether the process is restarted.

Monitor the status, resource usage and PID changes of the PM2 daemon process.

Easy-to-install Zabbix monitoring item templates have been provided.

1. Node.js server installation pm2-zabbix

npm install -g pm2-zabbix

Test whether the automatic discovery function is normal:

pm2-zabbix --discover

Output similar to that indicates successful installation:

{
"data": [
{
"{#PROCESS_ID}": "qb_node-0",
"{#PROCESS_NAME}": "qb_node"
},
{
"{#PROCESS_ID}": "qb_node-1",
"{#PROCESS_NAME}": "qb_node"
},
{
"{#PROCESS_ID}": "qb_node-2",
"{#PROCESS_NAME}": "qb_node"
},
{
"{#PROCESS_ID}": "qb_node-3",
"{#PROCESS_NAME}": "qb_node"
}
]
}

2.Clone code

git clonehttps://github.com/greatcare/pm2-zabbix.git

3. Zabbix Web management background import template file pm2-zabbix/install/zabbix-server/pm2-zabbix.template.xml

4. Add services to the Node.js server, select according to the server operating system version, and modify the service running user to be consistent with the Node.js user started with PM2

RHEL/CentOS 7 series:

cp pm2-zabbix/install/init/systemd/pm2-zabbix.service /usr/lib/systemd/system/

Modify the target file pm2-zabbix .service file content User item:

User=root

RHEL/CentOS 6 or 5 series:

cp pm2-zabbix/install/init/sysv/pm2-zabbix /etc/init.d/

Modify the target file pm2-zabbix file content DAEMON_USER item:

DAEMON_USER=root

5. Create a new soft connection and modify the real file path pointed by the soft connection according to your server

mkdir -p /etc/zabbix
ln -s /App/zabbix/etc/zabbix_agentd.conf /etc/zabbix/zabbix_agentd.conf
ln -s /App/zabbix/bin/zabbix_sender /usr/bin/zabbix_sender
ln -s `which node` /usr/bin/node
ln -s `which pm2-zabbix` /usr/local/bin/pm2-zabbix

6. Start the pm2-zabbix service

RHEL/CentOS 7 series:

systemctl start pm2-zabbix

RHEL/CentOS 6 Or 5 series:

service start pm2-zabbix

7. Modify the Zabbix Agent configuration file zabbix_agentd.conf and add other configurations

Include=/App/zabbix/etc/zabbix_agentd.conf.d/*.conf

8. Copy the Zabbix Agent configuration

cp pm2-zabbix/install/zabbix-agent/pm2-zabbix.conf /App/zabbix/etc/zabbix_agentd.conf.d/pm2.conf

9. Modify the configuration of pm2.conf. The sudo -u user is consistent with step 4. Colleagues modify the pm2-zabbix path

UserParameter=pm2.processes,sudo -u root /usr/local/bin/pm2-zabbix --discover

10. The server terminal executes the program visudo and adds sudo configuration

zabbix ALL=(ALL:ALL) NOPASSWD: /usr/local/bin/pm2-zabbix
Defaults:zabbix !requiretty

11. Restart Node .js server Zabbix Agent service

/etc/init.d/zabbix_agentd restart

12.Zabbix Web management background settings Node.js server Add link Template App PM2 template PM2 daemon CPU usage PM2 daemon memory usage Node process instance CPU usage managed by PM2 Memory usage of Node process instances managed by PM2

Understanding the JavaScript Engine: Implementation DetailsApr 17, 2025 am 12:05 AM

Understanding how JavaScript engine works internally is important to developers because it helps write more efficient code and understand performance bottlenecks and optimization strategies. 1) The engine's workflow includes three stages: parsing, compiling and execution; 2) During the execution process, the engine will perform dynamic optimization, such as inline cache and hidden classes; 3) Best practices include avoiding global variables, optimizing loops, using const and lets, and avoiding excessive use of closures.

Python vs. JavaScript: The Learning Curve and Ease of UseApr 16, 2025 am 12:12 AM

Python is more suitable for beginners, with a smooth learning curve and concise syntax; JavaScript is suitable for front-end development, with a steep learning curve and flexible syntax. 1. Python syntax is intuitive and suitable for data science and back-end development. 2. JavaScript is flexible and widely used in front-end and server-side programming.

Python vs. JavaScript: Community, Libraries, and ResourcesApr 15, 2025 am 12:16 AM

Python and JavaScript have their own advantages and disadvantages in terms of community, libraries and resources. 1) The Python community is friendly and suitable for beginners, but the front-end development resources are not as rich as JavaScript. 2) Python is powerful in data science and machine learning libraries, while JavaScript is better in front-end development libraries and frameworks. 3) Both have rich learning resources, but Python is suitable for starting with official documents, while JavaScript is better with MDNWebDocs. The choice should be based on project needs and personal interests.

From C/C to JavaScript: How It All WorksApr 14, 2025 am 12:05 AM

The shift from C/C to JavaScript requires adapting to dynamic typing, garbage collection and asynchronous programming. 1) C/C is a statically typed language that requires manual memory management, while JavaScript is dynamically typed and garbage collection is automatically processed. 2) C/C needs to be compiled into machine code, while JavaScript is an interpreted language. 3) JavaScript introduces concepts such as closures, prototype chains and Promise, which enhances flexibility and asynchronous programming capabilities.

JavaScript Engines: Comparing ImplementationsApr 13, 2025 am 12:05 AM

Different JavaScript engines have different effects when parsing and executing JavaScript code, because the implementation principles and optimization strategies of each engine differ. 1. Lexical analysis: convert source code into lexical unit. 2. Grammar analysis: Generate an abstract syntax tree. 3. Optimization and compilation: Generate machine code through the JIT compiler. 4. Execute: Run the machine code. V8 engine optimizes through instant compilation and hidden class, SpiderMonkey uses a type inference system, resulting in different performance performance on the same code.

Beyond the Browser: JavaScript in the Real WorldApr 12, 2025 am 12:06 AM

JavaScript's applications in the real world include server-side programming, mobile application development and Internet of Things control: 1. Server-side programming is realized through Node.js, suitable for high concurrent request processing. 2. Mobile application development is carried out through ReactNative and supports cross-platform deployment. 3. Used for IoT device control through Johnny-Five library, suitable for hardware interaction.

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
