 Description   

Steps to reproduce:

  1. Simply doesn't work. 
  2. It shows in item history correctly, when I open item from latest data.
  3. But it should show mapped representation in the Latest data item list as numeric value mapping works.

 

Result:
See screenshot...

Item Prototype configuration:

Value mapping:

How it looks wrong in Latest data:

How it looks correct in latest data item history:

I submitted one more bug report: ZBX-16188

I think these two might be related.

Comment by Andrejs Verza [ 2019 Jun 17 ]

Since these facts exist simultaneously:

  1. SNMP library returning an extra space in the end of Hex-String (can be observed even in snmpget's output).
  2. Zabbix does not preprocess the received data automatically.
  3. Zabbix trims trailing spaces in mapped values to avoid confusion when spaces left unintentionally.

... Therefore it is not possible to map a value with trailing spaces. Nevertheless, this can be easily solved by simply applying a TRIM function in preprocessing rule of the item prototype.

As per situation with mapped values in History and not in the Latest data - that's a bug. Mapping should only happen for trimmed values.

Resolved in development branch feature/ZBX-16176-4.0.
