Table of Contents
4 Latest data
Overview
In this section you can view the latest values gathered by items.
Graphs are also available for the item values.
This section contains:
Items are displayed with their name, time since the last check, last value, change amount, tags, and a link to a simple graph/history of item values.
Clicking on the item name opens the item menu with links to available graphs and the item configuration.
Values in the Last value column are displayed with unit conversion and value mapping applied. To view raw data, hover over the value.
Tags in the item list are clickable. If you click on a tag, this tag becomes enabled in the subfilter. The item list now displays the items corresponding to this tag and any other previously selected tags in the subfilter. Note that once the items have been filtered in this way, tags in the list are no longer clickable. Further modification based on tags (e.g. remove, add another filter) must be done in the subfilter.
If an item has errors, for example, has become unsupported, an information icon will be displayed in the Info column 
. Hover over the icon for details.
An icon with a question mark 
is displayed next to the item name for all items that have a description. Hover over this icon to see a tooltip with the item description.
If a host to which the item belongs is in maintenance, an orange wrench icon 
is displayed after the host's name.
Note: The name of a disabled host is displayed in red. Data of disabled hosts, including graphs and item value lists, is also accessible in Latest data.
By default, only values that fall within the last 24 hours are displayed. This limit has been introduced with the aim of improving initial loading times for large pages of the latest data. This time period can be extended by changing the value of the Max history display period parameter in Administration → [General](/manual/web_interface/frontend_sections/administration/general#gui).
For items with an update frequency of 1 day or more the change amount will never be displayed (with the default setting). Also in this case the last value will not be displayed at all if it was received more than 24 hours ago.
Buttons
View mode buttons being common for all sections are described on the Monitoring page.
Using filter
You can use the filter to display only the items you are interested in. For better search performance, data is searched with macros unresolved.
The filter icon 
is located above the table and the subfilter. Click on it to expand the filter.
The filter allows to narrow the list by host group, host, item name, tag and other settings. Specifying a parent host group in the filter implicitly selects all nested host groups. See Monitoring -> Problems for details on filtering by tags.
Show details allows to extend the information displayed for the items. Such details as the refresh interval, history and trends settings, item type, and item errors (fine/unsupported) are displayed.
Saving filter
Favorite filter settings can be saved as tabs and then quickly accessed by clicking on the respective tab above the filter.
See more details about saving filters.
Using subfilter
The subfilter allows to further modify the filtering from the main filter.
It contains clickable links for a quick access to related items. Items are related by common entity - host, tag name or value, item state, or data status. When an entity is clicked, the entity is highlighted with a gray background, and items are immediately filtered (no need to click Apply in the main filter). Clicking another entity adds it to the filtered results. Clicking the entity again removes the filtering.
Subfilters are generated based on the filtered data, which is limited to 1000 records. If there are 20 hosts each having 100 items (so 2000 records in total), only half of the hosts will be visible in the subfilter. If you want to see more records in the subfilter, you need to increase the value of Limit for search and filter results parameter (in Administration -> General -> GUI).
Unlike the main filter, the subfilter is updated together with each table refresh request to always get up-to-date information of available filtering options and their counter numbers.
For each entity group (e.g. tags, hosts) up to 10 rows of entities are displayed. If there are more entities, this list can be expanded to a maximum of 1000 entries (the value of SUBFILTER_VALUES_PER_GROUP in frontend definitions) by clicking on a three-dot icon displayed at the end. Once expanded to the maximum, the list cannot be collapsed. (Note that a non-expandable maximum of 100 is the limit before Zabbix 6.0.5.)
In the list of Tag values up to 10 rows of tag names are displayed. If there are more tag names with values, this list can be expanded to a maximum of 200 tag names by clicking on a three-dot icon displayed at the bottom. Once expanded to the maximum, the list cannot be collapsed. (Note that a non-expandable maximum of 20 rows is the limit before Zabbix 6.0.5.)
For each tag name up to 10 rows of values are displayed (expandable to 1000 entries (the value of SUBFILTER_VALUES_PER_GROUP in frontend definitions)).
The host options in the subfilter are available only if no hosts or more than one host is selected in the main filter.
By default, items with and without data are displayed in the item list. If only one host is selected in the main filter, the subfilter offers the option to filter only items with data, only without data, or both for this host.
A number next to each clickable entity indicates the number of items it has in the results of the main filter. Entities without items are not displayed, unless they were selected in the subfilter before.
Once one entity is selected, the numbers with other available entities are displayed with a plus sign indicating how many items may be added to the current selection.
Graphs
Ad-hoc graphs for comparing items
You may use the checkbox in the first column to select several items and then compare their data in a simple or stacked ad-hoc graph. To do that, select items of interest, then click on the required graph button below the table.
Links to value history/simple graph
The last column in the latest value list offers:
a History link (for all textual items) - leading to listings (Values/500 latest values) displaying the history of previous item values.
a Graph link (for all numeric items) - leading to a simple graph. However, once the graph is displayed, a dropdown on the upper right offers a possibility to switch to Values/500 latest values as well.
The values displayed in this list are "raw", that is, no postprocessing is applied.
The total amount of values displayed is defined by the value of Limit for search and filter results parameter, set in Administration → General.
