Consider HAR format

[neopaf]

Requirement - what kind of business use case are you trying to solve?

Traces

• sent by email
• used in offline environments
• stored to long-term archive
• attached to tracker software (I know about links. but they are not very good long-term)
• analysed with some 3rd party software (would allow emerging of such)
• represented in a filtered way
• auto-converted to tests

Problem - what in Jaeger blocks you from solving the requirement?

Currently traces go to DB and there is API, to extract them, but in proprietary format.

Proposal - what do you suggest to solve the problem or improve the existing situation?

Suggest to consider adding a button in UI to export it in HAR format, which seems flexible enough

And has lots of viewers.
Which could be base for analytic software.

We have canonical thrift and protobuf format, will have canonical json in the future. What value does HAR provide over those?

Yuri,
point is what we can do with what we export.
If there is a way to view a "canned trace" in any form, I think, people would be happier.
Found jaegertracing/jaeger-ui#214, sounds very good for me.
But that somewhat limits ways for people to view things.

HAR is also JSON, but there are several viewers for it, example:

#706... maybe we could use HAR as a base for our JSON general format?

Also my point is that if there is somewhat known JSON trace-related format, maybe consider that as a base?
https://dvcs.w3.org/hg/webperf/raw-file/tip/specs/HAR/Overview.html has custom fields to store our stuff.

In UI I've found only JSON. Missing something? Thrift and ProtoBuf, where are they?
(пользуясь случаем, спасибо за замечательный инструмент)

I believe a combination of #706 and jaegertracing/jaeger-ui#214 is sufficient to address all the scenarios you listed (except for the last two, I am not sure what those mean).

Спасибо за комплимент.
