6 Definitions定义

Overview概述

While many things in the frontend can be configured using the frontend itself, some customisations are currently only possible by editing a definitions file. 虽然可以使用前端本身配置前端中的许多内容，但目前只能通过编辑定义文件来进行某些自定义。

This file is defines.inc.php located in /include of the Zabbix HTML document directory.该文件是位于/包含Zabbix HTML文档目录的’define.inc.php’。

Parameters参数

Parameters in this file that could be of interest to users用户可能感兴趣的此文件中的参数:

  • ZBX_LOGIN_ATTEMPTS

Number of unsuccessful login attempts that is allowed to an existing system user before a login block in applied (see ZBX_LOGIN_BLOCK). By default 5 attempts. Once the set number of login attempts is tried unsuccessfully, each additional unsuccessful attempt results in a login block. Used with internal authentication only. 应用登录块之前允许现有系统用户的不成功登录尝试次数（请参阅ZBX_LOGIN_BLOCK）。 默认为5次尝试。 一旦尝试了设置的登录尝试次数失败，则每次额外的不成功尝试都会导致登录阻止。 仅与 internal身份验证一起使用。

  • ZBX_LOGIN_BLOCK

Number of seconds for blocking a user from accessing Zabbix frontend after a number of unsuccessful login attempts (see ZBX_LOGIN_ATTEMPTS). By default 30 seconds. Used with internal authentication only. 在多次登录尝试失败后阻止用户访问Zabbix前端的秒数（请参阅ZBX_LOGIN_ATTEMPTS）。 默认为30秒。 仅与 internal身份验证一起使用。

  • ZBX_PERIOD_DEFAULT

Default graph period, in seconds. One hour by default.默认图表周期，以秒为单位。 默认为一小时。

  • ZBX_MIN_PERIOD

Minimum graph period, in seconds. One hour by default.最短图表周期，以秒为单位。 默认为一小时。

  • ZBX_MAX_PERIOD

Maximum graph period, in seconds. Two years by default since 1.6.7, one year before that.最大图形周期，以秒为单位。 一年前，两年后默认为1.6.7。

  • ZBX_HISTORY_PERIOD

The maximum period to display history data in Latest data, Web, Overview pages and Data overview screen element in seconds. By default set to 86400 seconds (24 hours). Unlimited period, if set to 0 seconds. 在Latest data, Web, Overview页面和Data overview屏幕元素中以秒显示历史数据的最长期限。 默认设置为86400秒（24小时）。 无限期，如果设置为0秒。

  • GRAPH_YAXIS_SIDE_DEFAULT

Default location of Y axis in simple graphs and default value for drop down box when adding items to custom graphs. Possible values: 0 - left, 1 - right. 在将监控项添加到自定义图形时，简单图形中的Y轴的默认位置和下拉框的默认值。 可能的值：0 - 左，1 - 右。

Default默认值: 0

  • SCREEN_REFRESH_TIMEOUT (available since 2.0.4)

Used in screens and defines the timeout seconds for a screen element update. When the defined number of seconds after launching an update pass and the screen element has still not been updated, the screen element will be darkened.用于聚合图形并定义聚合图形元素更新的超时秒数。 当启动更新过程后定义的秒数且聚合图形元素仍未更新时，聚合图形元素将变暗。

Default默认值: 30

  • SCREEN_REFRESH_RESPONSIVENESS (available since 2.0.4)

Used in screens and defines the number of seconds after which query skipping will be switched off. Otherwise, if a screen element is in update status all queries on update are skipped until a response is received. With this parameter in use, another update query might be sent after N seconds without having to wait for the response to the first one. 在聚合图形中使用，并定义将关闭查询跳过的秒数。 否则，如果聚合图形元素处于更新状态，则会跳过所有更新查询，直到收到响应。 使用此参数后，可能会在N秒后发送另一个更新查询，而不必等待对第一个的响应。

Default默认值: 10

  • QUEUE_DETAIL_ITEM_COUNT

Defines retrieval limit of the total items queued. Since Zabbix 3.2.4 may be set higher than default value.定义排队的总监控项的检索限制。 由于Zabbix 3.2.4可能设置为高于默认值。

Default默认值: 500

  • ZBX_SHOW_SQL_ERRORS (available since 3.4.0)

With Debug mode disabled, only Zabbix Super Admin users will see SQL errors. Others will see a generic message: “SQL error. Please contact Zabbix administrator.” 如果为’true’，则在前端显示SQL错误。 如果更改为“false”，则仍会以调试模式 enabled向所有用户显示SQL错误。 在调试模式禁用的情况下，只有Zabbix Super Admin用户会看到SQL错误。 其他人会看到一条通用消息：“SQL错误。请联系Zabbix管理员。”

Default默认值: true
