ZABBIX 1.4 是来自 ZABBIX SIA 的下一代开源分布式监测系统。

这些发布说明包括在 ZABBIX 1.4 中什么是新特性、安装和升级要点。

== ZABBIX 1.4 中的新特性 ==
=== 自动发现 ===
ZABBIX distributed monitoring module allows to deploy ZABBIX systems easily.

The discovery supports IP ranges, service checks, agent and SNMP checks for
efficient auto-discovery.

=== 分布式监测 ===
ZABBIX distributed monitoring is made for complex environments consisting of different locations.

ZABBIX supports monitoring of an unlimited number of nodes. Centralized configuration allows easy all the nodes to be configured from a single location easily.

=== WEB monitoring ===
WEB monitoring module enables flexible and easy monitoring of availability and performance of WEB sites and WEB-based applications. It supports passing of GET and POST variables.

=== Installation Wizard ===
Installation Wizard automatically checks pre-requisites, database connectivity and generates a configuration file for WEB front end.

=== Support of new database engines ===
SQLite support has been implemented. It allows to use ZABBIX in embedded environments.

=== WEB interface improvements ===
WEB interface speed and usability have been improved greatly.

=== New notification methods ===
Native support of Jabber messaging has been introduced.

=== Many-to-many template linkage ===
More flexible host-template linkage saves time and makes the configuration of hosts more flexible and straight forward.

=== Database watchdog ===
ZABBIX server will automatically warns the group of users if the database is down and continues normal operations when the database is back.

=== XML data import/export ===
New XML data import and export functionality is an excellent way of sharing templates, hosts configuration and items/triggers related information.

=== Windows Vista Support ===
ZABBIX Windows agent supports Windows Vista, both 32 and 64 bit versions.

=== More flexible actions ===
Multiple operations (notifications, script execution) per action are supported. The choice of action calculation algorithm was introduced.

=== Server-side external checks ===
The server-side external checks can be used to introduce custom checks executed on ZABBIX server side.

=== New user permission schema ===
The old user permission schema is no longer supported. It was replaced by a new more efficient, yet simple, schema working on the level of user groups and host groups.

=== Hysteresis support ===
ZABBIX supports the use of different trigger expressions for going to ON and OFF states.

=== Slide show support ===
Several screens can be grouped into a slide show for better presentation.

=== ZABBIX server can spread the workload ===
across several servers

Groups of server side processes (discoverer, poller, HTTP poller, trapper, etc) can be located on different physical servers for better performance and availability.

=== Other improvements ===
==== The same code for UNIX and Windows agents ====
Sharing of agent code means better testing and stability.

==== New communication protocol ====
New communication protocol, compatible with 1.0 and 1.1.x, was developed.

==== Increased maximum size of background images ====
Maximum size of background images for maps was increased to 1.5-2MB, depending on configuration settings in php.ini.

==== New default templates ====
Built-in template got new naming, several new templates were introduced.

==== Flexible refresh intervals ====
ZABBIX support different refresh intervals for items for different days of week and time.

==== Stacked graphs ====
Stacked graphs are supported.

==== More flexible log rotation ====
New parameter, LogFileSize, controls parameters of log rotation for ZABBIX server and agents.

==== Support of static linkage ====
Static linkage of server and agent binaries was fixed.

==== Colour selection for graphs ====
Graphs support moredefaul colors and selection of RGB style color.

==== Log filtering on agent side ====
Log filtering by Posix style regular expression was implemented for more efficient monitoring of log files.

==== Improved configuration script ====
==== ZABBIX sender to read configuration parameter from agent’s configuration file ====
ZABBIX sender (zabbix_sender) can read server related parameters from agent’s
configuration file.

==== Support of macros in remote commands ====
Standard macros can be also used in remote commands.

==== New configuration parameters ====
Several server-side configuration parameters were introduced.

==== avg() will support integer type ====
Function avg() can be used for integer items.

==== An icon can be assigned to hosts having ‘unknown’ status ====
An icon for hosts in ‘unknown’ status can be defined for use in maps.

== What’s no longer supported ==
=== Repeated actions and notifications ===
Repeated actions and notification, poorly working in 1.1.x, are no longer supported. This functionality will be replaced by new escalation module in future releases of ZABBIX.

=== Bulk loader was replaces by XML Data Import/Export ===
Plain text bulk loader was replaced by more flexible XML Data Import/Export module.

=== User permissions on per-element level ===
User permissions of per-element level are no longer supported. It has been replaces by new user permission schema.

== Installation and Upgrade Notes ==
=== Installation ===
See the INSTALLATION section for full details.

=== Version compatibility ===
Agents from ZABBIX 1.0 and ZABBIX 1.1.x can be used with ZABBIX 1.4. No modification required.

ZABBIX 1.4 agents can be used with earlier versions of ZABBIX. Note that the newest agents do not support old keys of ZBABIX 1.0.

=== Upgrade procedure ===
The following steps have to be performed for successful upgrade from ZABBIX 1.3.x to 1.4.

The whole upgrade procedure may take several hours depending on size of ZABBIX database.

==== Stop ZABBIX server ===
Stop ZABBIX server to make sure that no new data are coming to database.

==== Backup existing ZABBIX database ====
This is very important step. Make sure that you have backup of your database. It will help if upgrade procedure fails (lack of disk space, power off, any unexpected problem).

==== Backup configuration files, PHP files and ZABBIX binaries ====
Make a backup copy of ZABBIX binaries, configuration files and PHP files.

==== Install new server binaries ====
You may use pre-compiled binaries or compile your own.

==== Review Server configuration parameters ====
Some parameters of zabbix_server.conf were changed in 1.4, new parameters added. You may want to review them.

==== Upgrade database ====
Database upgrade scripts are located in directory upgrade/dbpatches/1.4/<db engine>:
 MySQL: upgrade/dbpatches/1.4/mysql/patch.sql
 Oracle: upgrade/dbpatches/1.4/oracle/patch.sql
 PostgreSQL: upgrade/dbpatches/1.4/postgresql/patch.sql

----
 Note:
    Database upgrade may take quite significant time, several hours or more.
    It is recommended to test the upgrade in test environment.
----
Make sure that you have enough permissions (create table, drop table, create index, drop index). Also make sure that you have enough free disk space.

Normally you should have at least 2x more disk space than size of existing database.
----
Note:     These scripts are for upgrade from ZABBIX 1.1.x to 1.4 only!
----
==== Install new ZABBIX GUI ====
Follow Installation Instructions.

==== Start new ZABBIX binaries ====
Start new binaries. Check log files to see if the binaries are started successfully.
