The section in Monitoring → Latest data can be used to view latest values gathered by items as well as to access various graphs for the items.
When you open this page for the first time, nothing is displayed.
To access data, you need to make selections in the filter such as host group, host, application or item name.
In the list displayed, click on before a host and the relevant application to reveal latest values of that host and application. You can expand all hosts and all applications, thus revealing all items by clicking on in the header row.
Note: The name of a disabled host is displayed in red. Data of disabled hosts, including graphs and item value lists, is accessible in Latest data since Zabbix 2.2.0.
Items are displayed with their name, last check time, last value, change amount and a link to a simple graph/history of item values.
Only values that fall within the last 24 hours are displayed by default. This limit has been introduced with the aim of improving initial loading times for large pages of latest data. It is also possible to change this limitation by changing the value of ZBX_HISTORY_PERIOD constant in include/defines.inc.php.
You can use the filter to display only the items you are interested in. The Filter link is located above the table in the middle. You can use it to filter items by host group, host, application, a string in the item name; you can also select to display items that have no data gathered.
Specifying a parent host group implicitly selects all nested host groups since Zabbix 3.2.2. In Zabbix 3.2.0, 3.2.1, nested host groups are selected if the parent group is specified by a
parent group/* syntax.
Show details allows to extend displayable information on the items. Such details as refresh interval, history and trends settings, item type and item errors (fine/unsupported) are displayed. A link to item configuration is also available.
By default, items without data are shown but details are not displayed.
Graphs for comparing items
You may use the checkbox in the second column to select several items and then compare their data in a simple graph or stacked graph. To do that, select items of interest, then click on the required graph button below the table.
