=== Time synchronisation ===
It is very important to have precise system date on server with ZABBIX running. timed is one of most popular daemons that synchronises the host’s time with the time of other machines.

How to Get ZABBIX

Check the ZABBIX Home Page at http://www.zabbix.com for information about the current version and for downloading instructions.

Requirements

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:

Software Version Comments
Apache 1.3.12 or later
PHP 4.3 or later
PHP modules:

php-gd php-bcmath

4.3 or later PHP GD module must support PNG images.
MySQL

php-mysql

3.22 or later Required if MySQL is used as ZABBIX backend database.
Oracle

php-sqlora8

9.2.0.4 or later Required if Oracle is used as ZABBIX backend database.
PostgreSQL

php-pgsql

7.0.2 or later Required if PostgreSQL is used as ZABBIX backend database.Consider using PostgreSQL 8.x or later for much better performance.
SQLite

php-sqlite3

3.3.5 or later Required if SQLite is used as ZABBIX backend database.

Note: ZABBIX may work on previous versions of Apache, MySQL, Oracle, and PostgreSQL as well.


WEB browser on client side

Support for HTML and PNG images required. MS Explorer (5.xx and 6.xx) and Mozilla 1.x work perfectly. Cookies and JavaScript must be enabled. Other browsers may work with ZABBIX as well.

Choice of database engine

ZABBIX supports four database engines:

  • MySQL
  • Oracle
  • PostgreSQL
  • SQLite

Each database engine has its own advantages. We cannot recommend one over another.

Choice of database engine depends on the following aspects:

  • how powerful is your hardware
  • free or commercial database engine
  • how busy is ZABBIX Server

The table can be used as a general recommendation on choice of database engine.

Usage of ZABBIX Server Database engine of choice
Heavy duty Node/Standalone MySQL MyISAM
Light duty Node/Standalone PostgreSQL

MySQL MyISAM

Remote zero-admin Node PostgreSQL

SQLite

Standalone light duty MySQL MyISAM

Time synchronisation

It is very important to have precise system date on server with ZABBIX running. timed is one of most popular daemons that synchronises the host’s time with the time of other machines.
