Preprocessing step "Check for not supported value" stops server

XMLWordPrintable

    • Sprint 74 (Mar 2021)

      Create an item: test.trap which holds integer values.

      Create a calculated item that takes the last value and substracts the previous value:

      last("test.trap")-last("test.trap","#2")

      Create a preprocessing step:

      Deliver only one metric to test.trap item.

      zabbix_sender -z 127.0.0.1 -s trap -k test.trap -o 44

      Result

      When the calculated item will execute the expression, the server will crash with a message:
      server.log

      P.S.

      • If there are two metrics in item, then it works.
      • If a preprocessing step has been removed, then it works.

      Attaching template for faster reproducing:
