Basic Requirements in Zabbix Installation Process

Zabbix is an enterprise-class distributed open-source monitoring solution. Zabbix is released under the GPL and is, therefore, free for commercial and non-commercial use. Zabbix is an open-source monitoring software for various IT additions, including networks, servers, virtual machines (VMs), and cloud services. It also provides monitoring metrics such as network utilization, CPU, and disk utilization. Zabbix’s Web-based graphical user interface allows users to view their IT environment via customizable dashboards based on widgets, charts, network maps, slideshows, and reports. Zabbix can be deployed on-premise or in the cloud to give you complete control over your data. With Zabbix distributed monitoring, remote scripts collect data from multiple devices in distributed locations and summarize that data in a dashboard or report, for example: – Server availability across the country. Zabbix can send mail notifications based on predefined events in a user’s IT environment. The tool supports various operating systems such as Mac OS, Solaris, Linux, and many more. The tool uses a separate database to store the data and monitor the applications.

Zabbix lets you automatically detect problem conditions within the incoming metrics flow and maintain control of your infrastructure. It allows you to track millions of metrics from any source and is very flexible regarding threshold definition options. Zabbix delivers its users with multiple messaging channels to inform the appropriate people about the different types of events in their environment. Real-time monitoring of all areas is possible to find problems in the network and on the servers. The Zabbix tool collects the data and analyzes it so that performance metrics can be created. The Zabbix tool uses encrypted communication so that the data can be protected. It consists of several components: a server, a web interface, a database store, an agent, and a proxy.

Requirements of Zabbix Installation Process (6.2 (current))

Supported platforms

Due to the monitoring server’s security requirements and mission-critical nature, UNIX is the only operating system that can consistently provide the required performance, fault tolerance, and resilience. Zabbix works with market-leading versions.

 

For the platforms listed below, Zabbix components are available and thoroughly tested:

 

Platform  Server Agent  Agent2
Linux 
IBM AIX  – 
FreeBSD  – 
NetBSD  – 
OpenBSD  – 
HP-UX  – 
Mac OS X  – 
Solaris  – 
Windows  – 

Hardware requirements

Both physical and disc space are needed by Zabbix.

The number of hosts and characteristics being watched determines how much disc space is needed.

Allowing at least a few GBs of space in the database is recommended if you wish to preserve a lengthy history of the monitored parameters.

Multiple connections to a database server are necessary for each Zabbix daemon process.

The database engine’s configuration determines how much room is set aside for the connection.

CPU Requirements

Depending on the number of monitored parameters and the database engine selected, Zabbix, particularly notably the Zabbix database, may take a large number of CPU resources.

Other hardware

Zabbix’s SMS notification capability requires a serial communication port and a serial GSM modem.  
The USB-to-serial converter also functions.

Software Requirements

Modern web servers, top database engines, and the PHP scripting language are the foundation of Zabbix.

A place for big ideas.

Reimagine organizational performance while delivering a delightful experience through optimized operations.

Database size

Zabbix configuration data don’t expand too much and only take up a certain amount of disc space.

 

The following factors, which determine how much historical data is stored, largely determine the size of the Zabbix database:

 

  • Number of processed values per second
  • Housekeeper settings for history
  • Housekeeper setting for trends
  • Housekeeper settings for events

Time synchronization

On a server running Zabbix, having accurate system time is crucial. The most well-known daemon for synchronizing the host’s time with other computers is ntpd. On all systems where Zabbix components are active, synchronized system time is highly advised. On a server running Zabbix, having accurate system time is crucial. The most well-known daemon for synchronizing the host’s time with other computers is ntpd. On all systems where Zabbix components are active, synchronized system time is highly advised.

Network requirements

The list of open ports for each component is as follows, and it applies to the default configuration. 

 

Port  Components 
Frontend  http on 80, https on 443 
Server  10051 (for use with active proxy/agents) 
Active Proxy  10051 
Passive Proxy  10051

Conclusion

The list of open ports for each component is as follows, and it applies to the default configuration. Zabbix is an open-source monitoring software program intended to keep an eye on network servers and applications and aid users in locating network performance bottlenecks. Superior data-gathering performance is offered by Zabbix, which scales to large environments. The tool offers several features to simplify tracking and troubleshooting threats and issues. Real-time sector monitoring is a solution for detecting network and server problems. Real-time sector monitoring is possible to identify network and server problems. Performance metrics are created by the Zabbix tool using data that has been collected and analyzed. The Zabbix utility employs encrypted communication to safeguard the data. The Zabbix utility is much less expensive, requires no additional installation steps, and is much easier to set up on the user’s computer. The tool offers a number of capabilities to make tracking and fixing threats and problems easier.
