i have icingabeat set up from a master to a kafka cluster and am trying to set the severity to be text and not number e.g. 0=OK, 1=WARNING, 2=CRITICAL. i’m trying to set a processor to add/set the field but get an error that the add_field processor is not found:

2021-01-25T14:25:18.560Z INFO instance/beat.go:278 Setup Beat: icingabeat; Version: 6.5.4
2021-01-25T14:25:18.561Z ERROR instance/beat.go:800 Exiting: error initializing publisher: error initializing processors: the processor add_fields doesn’t exist
Exiting: error initializing publisher: error initializing processors: the processor add_fields doesn’t exist
failed!

here’s the snippet from the icingabeat.yml:

processors:
- rename:
    fields:
       - from: "icinga.check_result.state"
         to: "icinga.chk_state"
- add_fields:
    when:
       equals:
          icinga.chk_state: 2
    fields:
       icinga.chk_status: "CRITICAL"

i’m new to beat related things but the documentation i’ve read says this is possible - what am i missing? or is there another way to get the text of the severity instead of the number?

i had an old icingabeat version - when installing is did not do a apt-get update beforehand and had version 6.5.4 (amd64), libbeat 6.5.4. i did the update, installed again and have version 7.5.2 (amd64), libbeat 7.5.2 which is the latest i believe.

this has the add_fields processor
