I've been out of development for a bit but this seems like it's a similar concept. I'm all for having IDs to track across all projects.<br>

> Correlation_id and request_id could be the same identifier, but it could get hairy if they were. Imagine a single call to service A results in two calls to service B. I think you want each request to B to retain a separate request identifier for tracking purposes (like it is now), but then you want a second correlation_id that gives you simplified tracking across the entire surface of the call originating at A.<br>

we could track a call from Keystone all the way down.<br></blockquote><div><br></div><div style>Can't we do this now with a little bit of log parsing? Every time nova calls another service AFAIK we log the request ID to that service. </div>

Per User Action = Correlation ID<br>
Per Service = Request ID<br>

Is the purpose of using TLS for tracking those calls that don't pass the<br>
context? If so, could we use TLS for the Context object instead of<br>
explicitly passing it as a parameter?<br>
