Event Processor Not Applying Transformation as Expected about gnmic HOT 6 CLOSED

Yes all gomplate functions are imported

from gnmic.

Unfortunately that's not how event processors function:

• Processors apply only when the output format is set to event, the default format is json.
• Processors should always output a list of event messages (you cannot create an arbitrary json object using them)
  In your case, the processor is not being applied at all (format: event missing) and even if you set the format it will result in an error because what it returns is not a list of event messages.

If your goal is to return an arbitrary message (json or other) you can use the field msg-template: under your file output. It takes a Gotemplate that rendered with each received message as input.

Hello!
Can U put here some basic example of msg-template usage? Thank you!

I used TCP output to forward raw JSON and processed them with PyJQ. Works great. Thank you 🙂

outputs:

    type: file
    format: event
    msg-template: |
      {{range .}}
      {{if index .values "/interface/statistics/in-octets"}}
      Name: {{.name}}
      Interface Name: {{(index .tags "interface_name")}}
      Source: {{(index .tags "source")}}
      Subscription Name: {{(index .tags "subscription-name")}}
      InOctets: {{ index .values "/interface/statistics/in-octets" }}
      {{- end}}
      {{- end}}

This should print:

Name: sub1
Interface Name: ethernet-1/1
Source: $YOUR_ROUTER_NAME
Subscription Name: sub1
InOctets: 3857

Thanks a lot! And a small clarification - does the template supports gotemplate functions, string processing, for example?

Thanks again!
