<div>I'm going to refrain on commenting on thread local storage, but I have one question: Is this going to replace the request_id concept we've had in Nova/Glance for a while? 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.</div>

<div dir="ltr">Hi Everyone,<br>
<br>
We are planning to introduce a correlation_id across for effective debugging of requests that span across services.<br>
<br>
The idea is to pass the correlation_id as part of the request header across services. The job of generating/capturing the correlation_id and setting it as part of the request header is done through the correlation_id.py middleware available through oslo incubator.<br>
<br>
The services that uses the correlation_id middleware can in turn obtain the correlation_id from the request header and use it as part of logging & notification purposes.<br>
<br>
We are planning to make the correlation_id available for logging through thread local storage especially using the existing 'local.strong_store' reference. ( available from oslo-incubator/openstack/common/local.py).<br>
ie., by setting the correlation_id as attribute to 'local.strong_store' in the correlation_id middleware.<br>
<br>
Wish to know if its good idea to use the thread local storage from local.py for correlation_id so that it could be used by respective services.<br>
<br>
Thoughts?<br>
<br>
Regards,<br>
Venkatesh<br>
