Zabbix method of adding Node.js monitoring _node.js

At present, there are Pm2-zabbix tools on the Internet to achieve Zabbix monitoring node.js alarm, GitHub address.

Characteristics:

Automatic discovery of node.js processes through PM2 management.

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

Monitor the PM2 Daemon's own state, resource footprint, and PID changes.

A Zabbix monitoring item template is provided that is easy to install.

1.node.js Server Installation Pm2-zabbix

NPM install-g Pm2-zabbix

To test the automatic discovery feature is normal:

Pm2-zabbix--discover

A similar output indicates a 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. Cloning code

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

3.Zabbix Web Admin Background import template file Pm2-zabbix/install/zabbix-server/pm2-zabbix.template.xml

4.node.js Server Add service, select according to server operating system version, and modify service run user and Node.js user with PM2 start consistent

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 entry:

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:

Daemon_user=root

5. New soft connection, according to their own server to modify the soft connection to the real file path

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 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 additional configuration

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

8. Copy Zabbix Agent Configuration

CP pm2-zabbix/install/zabbix-agent/pm2-zabbix.conf/app/zabbix/etc/zabbix_agentd.conf.d/pm2.conf

9. Modify configuration pm2.conf Content sudo-u user and 4th step consistent, colleagues modify Pm2-zabbix path

Userparameter=pm2.processes,sudo-u Root/usr/local/bin/pm2-zabbix--discover

10. Server Terminal Execution Program Visudo add 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 Admin Settings node.js Server add link Template App PM2 template PM2 Daemon CPU Utilization PM2 Daemon memory Footprint PM2 Managed node process instance CPU Usage PM2 managed node process instance memory footprint

The above is a small set to introduce the Zabbix add Node.js monitoring method, I hope to help you, if you have any questions please give me a message, small series will promptly reply to everyone. Here also thank you very much for the cloud Habitat Community website support!
