1 Dashboard widgets

Overview

This section lists available dashboard widgets and provides details for widget configuration.

The following parameters are common for every single widget:

Name Enter a widget name.
Refresh interval Configure default refresh interval. Default refresh intervals for widgets range from No refresh to 15 minutes depending on the type of widget. For example: No refresh for URL widget, 1 minute for action log widget, 15 minutes for clock widget.

Refresh intervals for a widget can be set to a default value for all the corresponding users and also each user can set his own refresh interval value:

  • To set a default value for all the corresponding users switch to editing mode (click the Edit dashboard button, find the right widget, click the Edit button opening the editing form of a widget) and choose the required refresh interval from the dropdown list.
  • Setting a unique refresh interval for each user separately is possible in view mode by clicking the button for a certain widget.

Unique refresh interval set by a user has a priority over widget's setting and once it's set it's always preserved when widget's setting is modified.

Action log

In the action log widget you can display details of action operations (notifications, remote commands). It replicates information from Administration → Audit.

To configure, select Action log as type:

You may set the following specific options:

Sort entries by Sort entries by:
Time (descending or ascending)
Type (descending or ascending)
Status (descending or ascending)
Recipient (descending or ascending).
Show lines Set how many action log lines will be displayed in the widget.

Clock

In the clock widget you may display local, server or specified host time.

To configure, select Clock as type:

You may set the following specific options:

Time type Select local, server or specified host time.
Item Select the item for displaying time. To display host time, use the system.localtime[local] item. This item must exist on the host.
This field is available only when Host time is selected.

Data overview

In the data overview widget you can display the latest data for a group of hosts. It replicates information from Monitoring → Overview (when Data is selected as Type there).

To configure, select Data overview as type:

You may set the following specific options:

Host groups Select host groups. This field is auto-complete so starting to type the name of a group will offer a dropdown of matching groups. Scroll down to select. Click on 'x' to remove the selected.
Application Enter application name.
Show suppressed problems Mark the checkbox to display problems which would otherwise be suppressed (not shown) because of host maintenance.
Hosts location Select host location - left or top.

Discovery status

This widget displays a status summary of the active network discovery rules.

Favourite graphs

This widget contains shortcuts to the most needed graphs. The list of shortcuts is populated when you view a graph and then click on its Add to favourites button.

Favourite maps

This widget contains shortcuts to the most needed maps. The list of shortcuts is populated when you view a map and then click on its Add to favourites button.

Favourite screens

This widget contains shortcuts to the most needed screens and slide shows. The list of shortcuts is populated when you view a screen and then click on its Add to favourites button.

Graph

The graph widget provides a modern and versatile way of visualizing data collected by Zabbix using a vector image drawing technique. This graph widget is supported since Zabbix 4.0. The graph widget supported before can still be used and is now renamed to Graph (classic).

To configure, select Graph as type:

The Data set tab allows to add data sets and define their visual representation:

Data set Select hosts and items to display on the graph. Alternatively you may enter host and item patterns. Wildcard patterns may be used (for example, * will return results that match zero or more characters). Up to 50 items may be displayed in the graph.
Multiple entities (hosts, host patterns, items, item patterns) are separated with a comma. Therefore hosts or items with a comma in the name are not supported.
Host pattern and item pattern fields are mandatory.
Note that item names containing deprecated positional macros ($1-$9) are not resolved in this field. Therefore it will not be possible to add any of the items named like CPU $2 time individually to the graph using its resolved name (like CPU user time); while using its unresolved name CPU $2 time will add all corresponding items to the graph (e.g. CPU user time, CPU system time, CPU idle time, etc.).
Base colour Adjust base colour, either from the colour picker or manually. Base colour is used to calculate different colours for each item of the data set. Base colour input field is mandatory.
Draw Choose the draw type of the metric. Possible draw types are Line (set by default), Points and Staircase.
Width Set the line width. This option is available when Line or Staircase draw type is selected.
Point size Set the point size. This option is available when Points draw type is selected.
TransparencySet the transparency level.
Fill Set the fill level. This option is available when Line or Staircase draw type is selected.
Missing dataSelect the option for displaying missing data:
None - the gap is left empty
Connected - two border values are connected
Treat as 0 - the missing data is displayed as 0 values
Not applicable for Points draw type.
Y-axisSelect the side of the graph where Y-axis will be displayed.
Time shiftSet the time shift. Negative values allowed.

Existing data sets are displayed in a list. You may:

  • - click on this button to add a new data set
  • - click on the colour icon to expand/collapse data set details
  • - click on the move icon and drag a data set to a new place in the list

The Display options tab allows to define history data selection:

History data selection Set the source of the history data. Possible options are Auto (set by default, as implemented in classic graphs), History and Trends.

The Time period tab allows to set a custom time period:

Set custom time period Mark this checkbox to set custom time period for the graph (unmarked by default).
From Set the start time of the custom time period for the graph.
To Set the end time of the custom time period for the graph.

The Axes tab allows to customize how axes are displayed:

Left Y Mark this checkbox to make left Y axis visible. The Checkbox may be disabled in case it's not chosen either in Data set or in Overrides tab.
Right Y Mark this checkbox to make right Y axis visible. The Checkbox may be disabled in case it's not chosen either in Data set or in Overrides tab.
X-Axis Unmark this checkbox to hide X axis (marked by default).
Min Set the minimum value of the corresponding axis. Visible range minimum value of Y axis is specified.
Max Set the maximum value of the corresponding axis. Visible range maximum value of Y axis is specified.
Units Choose the unit for the graph axis values from the dropdown. If Auto option is chosen axis values are displayed using units of the first item of corresponding axis. Static option allows you to assign corresponding axis' custom name. If Static option is chosen and value input field left blank the corresponding axis' name will only consist of a numeric value.

The Legend tab allows to customize the graph legend:

Show legend Unmark this checkbox to hide the legend on the graph (marked by default).
Number of rows Set the number of rows to be displayed on the graph.

The Problems tab allows to customize the problem display:

Show problems Mark this checkbox to enable problem displaying on the graph (unmarked, i.e. disabled by default).
Selected items only Mark this checkbox to include problems for the selected items only to be displayed on the graph.
Problem hosts Select the problem hosts to be displayed on the graph. Wildcard patterns may be used (for example, * will return results that match zero or more characters).
Multiple hosts are separated with a comma. Therefore hosts with a comma in the visible name are not supported.
Severity Mark the problem severities to be displayed on the graph.
Problem Specify the problem's name to be displayed on the graph.
Tags Specify tag name and value to limit the number of problems displayed on the graph. To add more tag names and values, click on Add.
There are two calculation types for several conditions:
And/Or - all conditions must be met, conditions having same tag name will be grouped by Or condition
Or - enough if one condition is met
There are two ways of matching the tag value:
Contains - case-sensitive substring match (tag value contains the entered string)
Equals - case-sensitive string match (tag value equals the entered string)

The Overrides tab allows to add custom overrides for data set properties:

Overrides are useful when several items are selected for a data set using the * wildcard and you want to change how the items are displayed by default (e.g. default base colour or any other property).

Existing overrides (if any) are displayed in a list. To add a new override:

  • Click on the button
  • Select hosts and items for the override. Alternatively you may enter host and item patterns. Wildcard patterns may be used (for example, * will return results that match zero or more characters). Multiple entities (hosts, host patterns, items, item patterns) are separated with a comma. Therefore hosts or items with a comma in the name are not supported. Host pattern and item pattern fields are mandatory.
  • Click on , to select override parameters. At least one override parameter should be selected. For parameter descriptions, see the Data set tab above.

Graph (classic)

In the classic graph widget you can display a single custom graph or simple graph.

To configure, select Graph as type:

You may set the following specific options:

Source Select graph type:
Graph - custom graph
Simple graph - simple graph
Graph Select the custom graph to display.
This option is available if 'Graph' is selected as Source.
Item Select the item to display in a simple graph.
This option is available if 'Simple graph' is selected as Source.
Dynamic item Set graph to display different data depending on the selected host.

Map

In the map widget you can display either:

  • a single configured network map
  • one of the configured network maps in the map navigation tree (when clicking on the map name in the tree).

To configure, select Map as type:

You may set the following specific options:

Source type Select to display:
Map - network map
Map navigation tree - one of the maps in the selected map navigation tree
Map Select the map to display.
This option is available if 'Map' is selected as Source type.
Filter Select the map navigation tree to display the maps of.
This option is available if 'Map navigation tree' is selected as Source type.

Map navigation tree

This widget allows to build a hierarchy of existing maps while also displaying problem statistics with each included map and map group.

It becomes even more powerful if you link the Map widget to the navigation tree. In this case, clicking on a map name in the navigation tree displays the map in full in the Map widget.

Statistics with the top level map in the hierarchy display a sum of problems of all submaps and its own problems.

To configure the navigation tree widget, select Map navigation tree as type:

You may set the following specific options:

Show unavailable maps Mark this checkbox to display maps that the user does not have read permission to.
Unavailable maps in the navigation tree will be displayed with a greyed out icon.
Note that if this checkbbox is marked, available submaps are displayed even if the parent level map is unavailbale. If unmarked, available submaps to an unavailable parent map will not be displayed at all.
Problem count is calculated based on available maps and available map elements.

Plain text

In the plain text widget you can display latest item data in plain text.

To configure, select Plain text as type:

You may set the following specific options:

Items Select the items.
Items location Choose the location of selected items to be displayed in the widget.
