Sparkline graph does not display SNMP interface traffic #1
Description
The NetworkWidget sparkline does not display traffic data for SNMP-based interface items.
Although:
- Latest data shows correct traffic values
- History exists for the items
- Interface status is displayed correctly
The widget popup shows:
In: 0.00 B/s
Out: 0.00 B/s
And the sparkline graph remains flat.
Environment
- Zabbix version: 7.2
- Template: Template Network Generic Device SNMP
- Item type: SNMP agent
- Type of information: Numeric (unsigned)
- Preprocessing: Change per second
- Units: Bps
Expected Behavior
The sparkline should display interface traffic history (In/Out) similar to how it appears in the standard Zabbix item graph.
Actual Behavior
- Interface status works correctly.
- Traffic values appear in Latest Data.
- Sparkline shows 0.00 B/s and no graph.
Additional Notes
The issue appears only with SNMP traffic items.
