Fixed in development branch svn://svn.zabbix.com/branches/dev/ZBX-11099
as this briefly confused me - probably "all host's active items" means all enabled items, not active agent items
wiper Only items of type Zabbix agent (active). Active item nextcheck is updated after receiving a new value, so during maintenance period there are no updates and server would put them into queue.
richlv oh, so that was actually just the active agent items... thanks for fixing me 
(1) [D] Queue documentation can be improved by listing types of items that are not shown in queue. From is_counted_in_item_queue() these are:
- log, logrt, eventlog;
- ITEM_TYPE_TRAPPER:
- ITEM_TYPE_HTTPTEST:
- ITEM_TYPE_SNMPTRAP:

RESOLVED
sandis.neilands Thanks! CLOSED.
(2) [D] Items handled by proxies are included in the queue as well. This is surprising since proxies can be configured to hold off data (DataSenderFrequency) for an hour.

Encountered some existing usability issues while working on this change.
ZBXNEXT-1504 [F] [S] - filtering in the queue details
ZBXNEXT-1502 [F] - paging in the queue details
ZBXNEXT-1708 [F] - improve zabbix server styling in queue by proxy
ZBXNEXT-633 [F] [S?]- Would be nice in the "Administration->Queue->Details" report show also key of the item and it's update interval
ZBXNEXT-2255 [S] [P] [F] - Queue should list only separate items by status
Successfully tested.
Released in:
- pre-2.2.15rc1 r61861
- pre-3.0.5rc1 r61862
