Latest Data not showing information

[webbdj69]

Background:
I have a extremely basic template that has an item "Last System Backup Status". When a full system backup job is completed for a managed server, the software is configured to update this item using zabbix_sender. I have a corresponding triggers that raise an alert if the backup has failed, or if there has not been a successful backup in the past xx number of days...

The trigger for the lack of a recent backup appears to work correctly, as long as there is at least one initial value that has been assigned to that item.
Unfortunately, if the technician did not configure the notification script properly, that item is never updated, and we never have a notice that the backups are running.

Problem:
So I went to Latest Data, and in the name field entered "Last System Backup Status", and checked the box for "Show items without data".
I am looking for hosts where this item has never taken on a value.

To my surprise, I am seeing hosts that I know are getting backups and have successfully received the "ping"

If I click on "Graph" for that host, and change the drop down to "500 Latest Values", I see values in the history.
Yet the Latest data page is blank for both "Last Check" and "Last Value"

Sorry to say that but it is default behavior of "Latest data" page
Check https://www.zabbix.com/documentation...ng/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 latest data. It is also possible to change this limitation by changing the value of ZBX_HISTORY_PERIOD constant in include/defines.inc.php.

For items with 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.

Thank you for clearing that up. I overlooked that paragraph when I checked the documentation. I understand the reason for the limitation. It would be nice if they gave us an option on the latest data page to increase that time window. e.g. Data window: 1d..7d..30d.
I don't know that I would want to change the constant from it's default 24 hour period for something that I only do periodically.

Thanks again for responding to me so quickly.
