Hardware Requirements

Memory Requirements

ZABBIX requires both physical and disk memory. 128 MB of physical memory and 256 MB of free disk space could be a good starting point. However, the amount of required disk memory obviously depends on the number of hosts and parameters that are being monitored. If you're planning to keep a long history of monitored parameters, you should be thinking of at least a couple of gigabytes to have enough space to store the history in the database.

Each ZABBIX daemon process requires several connections to a database server. Amount of memory allocated for the connection depends on configuration of the database engine.

---

Note: The more physical memory you have, the faster the database (and therefore ZABBIX) works!

---

CPU Requirements

ZABBIX and especially ZABBIX database may require significant CPU resources depending on number of monitored parameters and chosen database engine.

Other hardware

A serial communication port and a serial GSM Modem required for using SMS notifications built-in ZABBIX.

Examples of hardware configuration

The table provides several hardware configurations:

Name	Platform	CPU/Memory	Database	Monitored hosts
Small	Ubuntu Linux	P2 350MHz/256MB	MySQL MyISAM	20
Medium	Ubuntu Linux 64 bit	AMD Athlon 3200+/2GB	MySQL MyISAM	500
Large	Ubuntu Linux 64 bit	Intel Dual Core 6400/4GB/RAID	MySQL MyISAM or PostgreSQL	>1000
Very large	RedHat Enterprise	Intel Xeon 2 CPU/8GB/RAID	MySQL MyISAM or PostgreSQL	>10000

---

Note: Actual configuration depends on number of active items and refresh rates very much. It is recommended to keep database engine on a separate box for large installations.

Supported Platforms

Due to security requirements and mission-critical nature of monitoring server, UNIX is the only operating system that can consistently deliver the necessary performance, fault tolerance and resilience. ZABBIX operates on market leading versions.

ZABBIX is tested on the following platforms:

• AIX
• FreeBSD
• HP-UX
• Linux
• Mac OS/X
• OpenBSD
• SCO Open Server
• Solaris

---

Note: ZABBIX may work on other Unix-like operating systems as well.

Software Requirements

ZABBIX is built around modern Apache WEB server, leading database engines, and the PHP scripting language.

The following software is required to run ZABBIX:
