8 Queue
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.
Queue is available only if Zabbix server is running.
From the dropdown in the upper right corner you can select:
- queue overview by item type
- queue overview by proxy
- list of delayed items

Overview by proxy
In this screen it is easy to locate if the problem is related to one of the proxies or the server.
