             Summary: logger: JSON: add CEE fields or a generic template for JSON structure
                 Key: ASTERISK-29517
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-29517
             Project: Asterisk
          Issue Type: Improvement
      Security Level: None
          Components: Core/Logging
    Affects Versions: 18.5.0
         Environment: all
            Reporter: Daniel Pocock


JSON Structured logging was added in Asterisk 14, it is mentioned in the release notes and JIRA issue ASTERISK-25425

The wiki doesn't have any details about it:

I found the template for the JSON fields here in the source code:
https://github.com/asterisk/asterisk/blob/master/main/logger.c#L270

It would be very useful to have the JSON CEE fields as an alternative.  They are described here:
https://cee.mitre.org/language/1.0-beta1/core-profile.html

When we are combining log events from different applications, it is useful if all the applications use the same field names.  The logs can be normalized by some other tool but it is more efficient if the preferred format is used from the source of the log messages.

I've recently done JSON CEE implementations for GStreamer, Kurento and reSIProcate processes:
