Latest Data in Zabbix does not show any data for some Items

[Teamster]

When I go into latest data, I see data for some items but not for others. These Items that do not have data never seemed to have displayed any data. Can someone tell me why data is being displayed for some Items but never for other Items. I know data should be coming through for these items.

By default only values that fall within the last 24 hours are displayed. Click on Graph (or History) for one such item and expand the time range. This will show if you have data, just too old to show.
