Overview

The Administration → General section contains a number of subsections for setting frontend-related defaults and customizing Zabbix.

The list of available subsections appears upon pressing on General in the Administration menu section. It is also possible to switch between subsections by using the title dropdown in the top left corner.

1 GUI

This section provides customization of several frontend-related defaults.

Configuration parameters:

Parameter	Description
Default language	Default language for users who have not specified a language in their profiles and guest users. For more information, see Installation of additional frontend languages.
Default time zone	Default time zone for users who have not specified a time zone in their profiles and guest users.
Default theme	Default theme for users who have not specified a theme in their profiles and guest users.
Limit for search and filter results	Maximum amount of elements (rows) that will be displayed in a web-interface list, for example, in Data collection → Hosts. Note: If set to, for example, ‘50’, only the first 50 elements will be displayed in all affected frontend lists. If some list contains more than fifty elements, the indication of that will be the ‘+’ sign in “Displaying 1 to 50 of 50+* found”*. Also, if filtering is used and still there are more than 50 matches, only the first 50 will be displayed.
Max number of columns and rows in overview tables	Maximum number of columns and rows to display in Data overview and Trigger overview dashboard widgets. The same limit applies to both columns and rows. If more rows and/or columns than shown exist, the system will display a warning at the bottom of the table: “Not all results are displayed. Please provide more specific search criteria.”
Max count of elements to show inside table cell	For entries that are displayed in a single table cell, no more than configured here will be shown.
Show warning if Zabbix server is down	This parameter enables a warning message to be displayed in a browser window if the Zabbix server cannot be reached (possibly down). The message remains visible even if the user scrolls down the page. When hovered over, the message is temporarily hidden to reveal the contents underneath it. This parameter is supported since Zabbix 2.0.1.
Working time	This system-wide parameter defines working hours. In graphs, working time is displayed as a white background and non-working time is displayed as gray. See Time period specification page for description of the time format. User macros are supported (since Zabbix 3.4.0).
Show technical errors	If checked, all registered users will be able to see technical errors (PHP/SQL). If unchecked, the information is only available to Zabbix Super Admins and users belonging to the user groups with enabled debug mode.
Max history display period	Maximum time period for which to display historical data in Monitoring subsections: Latest data, Web, and in the Data overview dashboard widget. Allowed range: 24 hours (default) - 1 week. Time suffixes, e.g. 1w (one week), 36h (36 hours), are supported.
Time filter default period	Time period to be used in graphs and dashboards by default. Allowed range: 1 minute - 10 years (default: 1 hour). Time suffixes, e.g. 10m (ten minutes), 5w (five weeks), are supported. Note: when a user changes the time period while viewing a graph, this time period is stored as user preference, replacing the global default or a previous user selection.
Max period for time selector	Maximum available time period for graphs and dashboards. Users will not be able to visualize older data. Allowed range: 1 year - 10 years (default: 2 years). Time suffixes, e.g. 1y (one year), 365w (365 weeks), are supported.

2 Autoregistration

In this section, you can configure the encryption level for active agent autoregistration.

Parameters marked with an asterisk are mandatory.

Configuration parameters:

Parameter	Description
Encryption level	Select one or both options for encryption level: No encryption - unencrypted connections are allowed PSK - TLS encrypted connections with a pre-shared key are allowed
PSK identity	Enter the pre-shared key identity string. This field is only available if ‘PSK’ is selected as Encryption level. Do not put sensitive information in the PSK identity, it is transmitted unencrypted over the network to inform a receiver which PSK to use.
PSK	Enter the pre-shared key (an even number of hexadecimal characters). Maximum length: 512 hex-digits (256-byte PSK) if Zabbix uses GnuTLS or OpenSSL library, 64 hex-digits (32-byte PSK) if Zabbix uses mbed TLS (PolarSSL) library. Example: 1f87b595725ac58dd977beef14b97461a7c1045b9a1c963065002c5473194952 This field is only available if ‘PSK’ is selected as Encryption level.

3 Images

The Images section displays all the images available in Zabbix. Images are stored in the database.

The Type dropdown allows you to switch between icon and background images:

Icons are used to display network map elements
Backgrounds are used as background images of network maps

Adding image

You can add your own image by clicking on the Create icon or Create background button in the top right corner.

Image attributes:

Parameter	Description
Name	Unique name of an image.
Upload	Select the file (PNG, JPEG, GIF) from a local system to be uploaded to Zabbix. Note that it may be possible to upload other formats that will be converted to PNG during upload. GD library is used for image processing, therefore formats that are supported depend on the library version used (2.0.28 or higher is required by Zabbix).

Maximum size of the upload file is limited by the value of ZBX_MAX_IMAGE_SIZE that is 1024x1024 bytes or 1 MB.

The upload of an image may fail if the image size is close to 1 MB and the max_allowed_packet MySQL configuration parameter is at a default of 1MB. In this case, increase the max_allowed_packet parameter.

4 Icon mapping

This section allows creating the mapping of certain hosts with certain icons. Host inventory field information is used to create the mapping.

The mappings can then be used in network map configuration to assign appropriate icons to matching hosts automatically.

To create a new icon map, click on Create icon map in the top right corner.

Configuration parameters:

Parameter	Description
Name	Unique name of icon map.
Mappings	A list of mappings. The order of mappings determines which one will have priority. You can move mappings up and down the list with drag-and-drop.
Inventory field	Host inventory field that will be looked into to seek a match.
Expression	Regular expression describing the match.
Icon	Icon to use if a match for the expression is found.
Default	Default icon to use.

5 Regular expressions

This section allows creating custom regular expressions that can be used in several places in the frontend. See Regular expressions section for details.

6 Trigger displaying options

This section allows customizing how trigger status is displayed in the frontend and trigger severity names and colors.

Parameter	Description
Use custom event status colors	Checking this parameter turns on the customization of colors for acknowledged/unacknowledged problems.
Unacknowledged PROBLEM events, Acknowledged PROBLEM events, Unacknowledged RESOLVED events, Acknowledged RESOLVED events	Enter new color code or click on the color to select a new one from the provided palette. If blinking checkbox is marked, triggers will blink for some time upon the status change to become more visible.
Display OK triggers for	Time period for displaying OK triggers. Allowed range: 0 - 24 hours. Time suffixes, e.g. 5m, 2h, 1d, are supported.
On status change triggers blink for	Length of trigger blinking. Allowed range: 0 - 24 hours. Time suffixes, e.g. 5m, 2h, 1d, are supported.
Not classified, Information, Warning, Average, High, Disaster	Custom severity names and/or colors to display instead of system default. Enter new color code or click on the color to select a new one from the provided palette. Note, that custom severity names entered here will be used in all locales. If you need to translate them to other languages for certain users, see Customizing trigger severities page.

7 Geographical maps

This section allows selecting geographical map tile service provider and configuring service provider settings for the Geomap dashboard widget. To provide visualization using the geographical maps, Zabbix uses open-source JavaScript interactive maps library Leaflet. Please note that Zabbix has no control over the quality of images provided by third-party tile providers, including the predefined tile providers.

Parameter	Description
Tile provider	Select one of the available tile service providers or select Other to add another tile provider or self-hosted tiles (see Using a custom tile service provider).
Tile URL	The URL template for loading and displaying the tile layer on geographical maps. This field is editable only if Tile provider is set to Other. The following placeholders are supported: {s} represents one of the available subdomains; {z} represents zoom level parameter in the URL; {x} and {y} represent tile coordinates; {r} can be used to add “@2x” to the URL to load retina tiles. Example: `https://{s}.example.com/{z}/{x}/{y}{r}.png`
Attribution text	Tile provider attribution text to be displayed in a small text box on the map. This field is visible only if Tile provider is set to Other.
Max zoom level	Maximum zoom level of the map. This field is editable only if Tile provider is set to Other.

Using a custom tile service provider

The Geomap widget is capable to load raster tile images from a custom self-hosted or a third-party tile provider service. To use a custom third-party tile provider service or a self-hosted tile folder or server, select Other in the Tile provider field and specify the custom URL in the Tile URL field using proper placeholders.

8 Modules

This section allows to administer custom frontend modules.

Click on Scan directory to register/unregister any custom modules. Registered modules will appear in the list, along with their details. Unregistered modules will be removed from the list.

You may filter modules by name or status (enabled/disabled). Click on the module status in the list to enable/disable a module. You may also mass enable/disable modules by selecting them in the list and then clicking on the Enable/Disable buttons below the list.

9 Connectors

This section allows to configure connectors for Zabbix data streaming to external systems over HTTP.

Click on Create connector to configure a new connector.

You may filter connectors by name or status (enabled/disabled). Click on the connector status in the list to enable/disable a connector. You may also mass enable/disable connectors by selecting them in the list and then clicking on the Enable/Disable buttons below the list.

10 Other parameters

This section allows configuring miscellaneous other frontend parameters.

Parameter	Description
Frontend URL	URL to Zabbix web interface. This parameter is used by Zabbix web service for communication with frontend and should be specified to enable scheduled reports.
Group for discovered hosts	Hosts discovered by network discovery and agent autoregistration will be automatically placed in the host group, selected here.
Default host inventory mode	Default mode for host inventory. It will be followed whenever a new host or host prototype is created by server or frontend unless overridden during host discovery/autoregistration by the Set host inventory mode operation.
User group for database down message	User group for sending alarm message or ‘None’. Zabbix server depends on the availability of the backend database. It cannot work without a database. If the database is down, selected users can be notified by Zabbix. Notifications will be sent to the user group set here using all configured user media entries. Zabbix server will not stop; it will wait until the database is back again to continue processing. Notification consists of the following content: `[MySQL\|PostgreSQL\|Oracle] database <DB Name> [on <DB Host>:<DB Port>] is not available: <error message depending on the type of DBMS (database)>` <DB Host> is not added to the message if it is defined as an empty value and <DB Port> is not added if it is the default value (“0”). The alert manager (a special Zabbix server process) tries to establish a new connection to the database every 10 seconds. If the database is still down the alert manager repeats sending alerts, but not more often than every 15 minutes.
Log unmatched SNMP traps	Log SNMP trap if no corresponding SNMP interfaces have been found.

Authorization

Parameter	Description
Login attempts	Number of unsuccessful login attempts before the possibility to log in gets blocked.
Login blocking interval	Period of time for which logging in will be prohibited when Login attempts limit is exceeded.

Security

Parameter	Description
Validate URI schemes	Uncheck the box to disable URI scheme validation against the whitelist defined in Valid URI schemes. (enabled by default).
Valid URI schemes	A comma-separated list of allowed URI schemes. Applies to all fields in the frontend where URIs are used (for example, map element URLs). this field is editable only if Validate URI schemes is selected.
X-Frame-Options HTTP header	Value of HTTP X-Frame-options header. Supported values: SAMEORIGIN (default) - the page can only be displayed in a frame on the same origin as the page itself. DENY - the page cannot be displayed in a frame, regardless of the site attempting to do so. null - disable X-Frame-options header (not recommended). Or a list (string) of comma-separated hostnames. If a listed hostname is not among allowed, the SAMEORIGIN option is used.
Use iframe sandboxing	This parameter determines whether retrieved URL content should be put into the sandbox or not. Note, that turning off sandboxing is not recommended.
Iframe sandboxing exceptions	If sandboxing is enabled and this field is empty, all sandbox attribute restrictions apply. To disable some of the restrictions, specified them in this field. This disables only restrictions listed here, other restrictions will still be applied. See sandbox attribute description for additional information.
