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 分布式模块可以很方便地布置 ZABBIX 系统。

自动发现支持 IP 范围、服务检查、代理和 SNMP 模块，以便有效地进行自动发现。

=== 分布式监测 ===
ZABBIX 分布式监测可以将不同的区域组成一个复杂的环境。

ZABBIX 支持无限节点的监测。集中式配置可以在一个地方很方便地对所有节点进行配置。

=== WEB 监测 ===
WEB 监测模块可以灵活方便地监测 WEB 站点和基于 WEB 应用程序的可用性和性能，它通过 GET 和 POST 变量来实现。

=== 安装向导 ===
安装向导自动检测安装必备条件、数据连接，并为 WEB 前端生成一个配置文件。

=== 支持新的数据库引擎 ===
SQLite 支持已实现，这样就可以在嵌入式系统中使用 ZABBIX 了。

=== 改善 WEB 界面 ===
WEB 界面的速度和易用性得到极大的改善。

=== 新的通知方法 ===
推荐使用本地化的 Jabber 信息支持

=== 多对多的模板关联 ===
更加灵活的主机模块关联可以节省时间，同时可以更加直接和灵活地配置主机。

=== 数据库监测器 ===
ZABBIX 服务器会在数据库宕机时自动向用户组发警告，并在数据库恢复正常之后继续正常的操作。

=== XML 数据的导入导出 ===

新的 XML 数据导入和导出功能是共享模块、主机配置和监测项/触发器相关信息的极佳方式

=== Windows Vista 支持 ===
ZABBIX 的 Windows 代理可以支持 Windows Vista，包括32位和64位的。

=== 更加灵活的动作 ===
支持一个动作的多个操作（通知、执行脚本）等，并推荐选择的动作计算算法。

=== 服务器端外部检测 ===

服务器端外部检测常被用来在 ZABBIX 服务器端执行自定义检测。

=== 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.
''斜体文字''

== 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.
