Problem

In Monitoring → Latest data, long item names are truncated after 62 characters, making it difficult to identify items when the important part of the name appears later (common with network interface descriptions; as example). This forces users to guess or open item details, slowing down triage.

Example:

• Cisco/Nexus templates include interface descriptions at the end of the name.
• The current Latest Data view utilizes the ZBX_STYLE_OVERFLOW_ELLIPSIS class on the Item Name, which hides the important part of the Item Name.

This behavior is shown in the following screenshot:

Who’s affected

•   NOC/SRE operators scanning Latest data during incidents
•   Network engineers using SNMP templates where interface descriptions are appended to item names (e.g., Cisco/Nexus)

User Story

• When scanning Latest data, I want to see or quickly reveal the full item name so that I can identify the correct item without leaving the page.

• I want to copy the full item name easily for search or ticketing purposes.

Proposed Solution

Two possible approaches:

1. Change the default (simplest)

Replace ZBX_STYLE_OVERFLOW_ELLIPSIS with ZBX_STYLE_WORDWRAP for $item_name in monitoring.latest.view.html.php.

• Pros: Minimal change; works immediately for all users.

• Cons: Increases row height for long names; no opt-out.

The result would look like the following screenshot

2. Configurable “Show full names” option

Add a checkbox in the Latest data filter (next to “Show details”) to toggle between truncated and wrapped names.

• Default: Ellipsis (current behavior).

• When enabled: Apply word-wrap for the Name column.

• Preference is configurable via the Filter tab, just like 'Show details'

Pros: Flexible; keeps compact view for those who prefer it.
Cons: Requires UI and JavaScript changes; slightly more effort.

I imagine something like this:

Acceptance Criteria

1. I can view the entire item name without leaving the Latest data page.

1. I can copy the full name easily.

1. Table layout remains readable; performance impact is negligible.

Risks

• Wrapping long names may cause tall rows, impacting scanning speed.

• Large numbers of wrapped items could slightly increase DOM height and rendering time.
