    Value of type "string" is not suitable for value type "Numeric (unsigned)".

    Hello,

    I'm pretty new to Zabbix 6.0, and ran into an issue with preprocessing of an SNMP Trap item.

    Item:


    regex Parameters: iso.3.6.1.4.1.33555.3.5.54.4.0 type=2 value=INTEGER: [1-9][0-9]* /1

    ​​


    Error: Value of type "string" is not suitable for value type "Numeric (unsigned)". Value "NaN"

    ​​
    The Trap message:
    08:47:23 2024/05/07 ZBXTRAP 10.170.2.211
    PDU INFO:
    messageid 0
    requestid 123456789
    notificationtype TRAP

    iso.3.6.1.6.3.1.1.4.1.0 type=6 value=OID: iso.3.6.1.4.1.33555.3.0.54
    iso.3.6.1.4.1.33555.3.5.54.1.0 type=2 value=INTEGER: 5
    iso.3.6.1.4.1.33555.3.5.54.3.0 type=2 value=INTEGER: 2
    iso.3.6.1.4.1.33555.3.5.54.4.0 type=2 value=INTEGER: 501​

    I would need to monitor the temperature of the OID .3.6.1.4.1.33555.3.5.54.4.0​.

    The TrapReceiver is receiving traps

    It looks like no regex is working for me. Anywone has an idea what I'm doing wrong?

      I found the issue. I had to use iso\.3\.6\.1\.4\.1\.33555\.3\.5\.54\.4\.0 type=2 value=INTEGER:\s+(\d+)and \1 instead of /1.

          iso\.3\.6\.1\.4\.1\.33555\.3\.5\.54\.4\.0 type=2 value=INTEGER:\s+(\d+)

          You have not allocated a capture group

              Thank you for your answer!

              For some reason, I still get the same error: Value of type "string" is not suitable for value type "Numeric (unsigned)". Value "NaN"

              In a regex debugger its working fine. The result I get from the internal tester, is just /gm. The JavaScript result is just NaN.​

              Any tips would be much appreciated!

                      You are absolutely using the preprocessing rule incorrectly.
                      What does "\gm" have to do with it??? The number of the matched group should be indicated there!
                      Look in the documentation https://www.zabbix.com/documentation.../preprocessing

                      PS
                      It's good that you found your mistakes yourself! Good luck!
