Overview

In the Administration → Queue section items that are waiting to be updated are displayed.

Ideally, when you open this section it should all be "green" meaning no items in the queue. If all items are updated without delay, there are none waiting. However, due to lacking server performance, connection problems or problems with agents, some items may get delayed and the information is displayed in this section. For more details, see the Queue section.

The Administration → Queue section contains the following pages:

• Queue overview — displays queue by item type;
• Queue overview by proxy — displays queue by proxy;
• Queue details — displays a list of delayed items.

The list of available pages appears upon pressing on Queue in the Administration menu section. It is also possible to switch between pages by using a title dropdown in the top left corner.
