[asterisk-bugs] [JIRA] (ASTERISK-29517) logger: JSON: add CEE fields or a generic template for JSON structure

[Daniel Pocock (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-29517?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=256260#comment-256260 ] 

Daniel Pocock commented on ASTERISK-29517:
------------------------------------------

Yes, I'm probably going to add this myself or collaborate with somebody else who will submit a patch

We did this in a few other projects already, it has just been completed and tested in Kamailio recently, Asterisk will be next

https://github.com/kamailio/kamailio/pull/2848

Obviously this is most useful when different applications (reSIProcate, Kamailio, Asterisk, GStreamer, Kurento) use a structure that is identical or as close as possible to identical.  Feel free to have a look at the Kamailio implementation and comment if you are happy for me to contribute something identical for Asterisk.

> JSON Structured logging was added in Asterisk 14, it is mentioned in the release notes and JIRA issue ASTERISK-25425
> https://wiki.asterisk.org/wiki/display/AST/New+in+14
> https://issues.asterisk.org/jira/browse/ASTERISK-25425
> The wiki doesn't have any details about it:
> https://wiki.asterisk.org/wiki/display/AST/Logging+Configuration
> 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:
> https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/847
> https://github.com/Kurento/kurento-media-server/pull/17
> https://github.com/resiprocate/resiprocate/commit/d1df9aeb956be79253560fe3628b3f37a4ef94f2
