 +=== Test item from UI ===
 +
 +In previous Zabbix versions it was difficult to tell if a newly-configured [[:​manual/​config/​items|item]] was configured correctly or not. For that you needed to wait until the item tried to gather some data.
 +
 +In the new version it is possible to test the item (template item, item prototype, low-level discovery rule) from the user interface even before saving and, if configured correctly, get a real value in return. ​
 +
 +Item testing is not supported for active items and some simple checks (''​icmpping*'',​ ''​vmware.*''​ items).
 +
 +To test the item, click on the //Test// button at the bottom of the item configuration form. 
 +
 +{{:​manual:​config:​items:​item_test_button.png|}}
 +
 +The item testing form has fields for the required host parameters (host address, port, proxy name/no proxy). These fields are context aware:
 +
 +  * The values are pre-filled when possible, i.e. for items requiring an agent, by taking the information from the selected agent interface of the host
 +  * The values have to be filled manually for template items
 +  * The fields are disabled when not needed in the context of the item type (e.g. the host address field is disabled for calculated and aggregate items, the proxy field is disabled for calculated items)
 +
 +To test the item, click on //Get value//. If the value is retrieved successfully,​ it will fill the //Value// field.
 +
 +{{:​manual:​introduction:​item_test_highlighted.png?​600|}}
 +
 +A successfully retrieved value from host can also be used to test the preprocessing steps. ​
 +
 +In fact, the item testing form is an extension of the preprocessing testing form already known in recent Zabbix versions. So if previously you could test preprocessing steps only against a hypothetical input value, now it is also possible to test preprocessing against a real test value just received.
 +
 +To test the preprocessing steps against the real value, click on //Get value and test//.

 A stronger bcrypt cryptography is now used for hashing user passwords instead of MD5. The change to the stronger cryptography after the upgrade is automatic, i.e. no effort on the user side is required. Note that passwords longer than 72 characters will be truncated. A stronger bcrypt cryptography is now used for hashing user passwords instead of MD5.
