Hi! I forgot to ever present myself. I'm Alejandro, AI Engineer at Inditex.
Hi! I don't know if there is a bug, but since we have changed to use phoenix-client self hosted instead of the whole server in our container we had to change to the log_spans function as log_traces is not supported in the client and now that we are trying to log spans into non-existent projects, the project is not being created. It used to be created automatically whenever we chose a project identifier that didn't exist but now it returns an error

Is it a problem on our end or is it a bug?
Thank you so much!
Hello! We have a self hosted phoenix-client in azure that is redirected through a proxy so the root path is /monitoring. We are correctly doing
- name: PHOENIX_HOST_ROOT_PATH
value: /monitoringto change it as env variable during deployment but when we press the button share in a trace the output given doesn't contain the root path so when sharing with another people of the team they have to enter the phoenix an search for the trace or add the /monitoring by hand. Is it a problem with the current phoenix-client implementation or should we add another env variable/make any changes?
Hi! Why does the package arize-phoenix-client not have an implementation of log_traces? The problem with this is that we are changing our implementation to self host with the arize-phoenix-client package to avoid overhead and because log_traces is not implemented we are using instead log_spans, but since the log_spans function wasn't implemented until arize-phoenix 10.12.0, this makes so it is no longer backwards compatible with our servers that have a previous version deployed.
RunLLM I would want to add the traces in this way to be backwards compatible with our previous implementation with the whole arize-phoenix
trace = {
"name": name,
"attributes": {
"input": {
"value": input_data,
"mime_type": input_mime_type
},
"output": {
"value": output,
"mime_type": output_mime_type
}
},
"start_time": start_time,
"end_time": time.time(),
"status_code": "OK",
"status_message": None,
"context": {
"trace_id": execution_id,
"span_id": span_id,
},
"span_kind": "CHAIN",
"parent_id": self.parent_span_id,
}The problem is that whenever i add parent_id, status_message or the attributes dict it fails, how should the trace be constructed? I am not able to find an standard in the docs
Hi! We are trying to use the phoenix client for our application with self hosted phoenix in docker instead of just having the whole phoenix package but we are having some problems when trying to log traces:
There is not function log_traces in the phoenix client, for a workaround we thought to use the log_spans that is included in the client and use a span dict similar to the one appearing in the docs
This log_spans is still not working, even when we try the examples appearing in the docs to log a span like this it is still failing:
# Log spans
>>> spans = [
... {
... "id": "1",
... "name": "test",
... "context": {"trace_id": "123", "span_id": "456"},
... }
... ]
>>> result = client.spans.log_spans(
... project_identifier="my-project",
... spans=spans

We would like to avoid using the whole arize-phoenix package to reduce overhead. Thank you so much!!
