#### Preprocessing throughput internal item

A new [``zabbix[preprocessing]``](/manual/config/items/itemtypes/internal#preprocessing) internal item has been added that returns a JSON containing statistics of the values received by the preprocessing manager:

- *queued* - the number and size of queued values that require preprocessing (counter);
- *direct* - the number and size of queued values that do not require preprocessing (counter);
- *queue* - the count of values enqueued in the preprocessing queue (same as `zabbix[preprocessing_queue]`)

For more details on the return values, refer to the [Return values for net.dns.get](/manual/appendix/items/return_values_net_dns_get) page.
