Goal:

A) Create a new item and a simple trigger for that item
B) Create a more complex trigger, involving various items from different hosts

Modus operandi A):

= Manual approach =

• Create the item
• Memorize or copy exact host name and item key; that can be very difficult in cases
• Switch to triggers.php
• "Create trigger"
• Type or paste it and hope everything goes well
• Save

= UI approach =

• Create the item
• Switch to triggers.php
• "Create trigger"
• Click "Edit"
• Click "Select"
• Navigate for the right host and item
• Adapt the expression or leave it as it is and edit later
• Click "Insert"
• Save

B):

Much like before, you'd have to go through all the steps over and over.

To me it seems, the process could be improved in two ways:

1.) Make it easier to create a simple trigger expression for a single item. This could be achieved via a link in the Wizard column on items.php, or better: The Triggers column. It would take you the trigger editor, with host and item already filled in.

2.) Try to get rid of the popups and integrate the list of all available items in the trigger form, to comfortably pick items.
