🐛Bug: Gemini streaming with Langchain spans are not logged

[amitjoy]

Which component is this feature for?

Langchain Instrumentation

🔖 Feature description

Consider intercepting existing callback handlers since they might have metrics to be published as well

🎤 Why is this feature needed ?

In my current scenario, I have a RAG chain that already utilizes a callback handler while sending the request to the Vertex AI. The custom callback internally is called more than once and the callback calculates latencies of each internal requests to the LLM. Once these latencies are calculated, I am sending them using Traceloop.set_association_properties(info.model_dump()) in the handler but it is never part of the span. I think it would be really great if traceloop can also intercept existing callback handlers to ensure that any Traceloop related metrics that are expected to be published from these customer handlers, are also considered.

✌️ How do you aim to achieve this?

Aspect oriented programming should be leveraged to introduce cross cutting concerns. Or, we may think of introducing custom decorators for these callbacks where such metrics are added.

Thanks @amitjoy for reporting this though I'm not completely sure I understood. Can you provide an example and what's the output you're expecting to get?

[amitjoy]

Sure. I would like to send few metrics while instrumenting langchain using Traceloop (OpenLLMetry). I am actually using sentry as an OpenTelemetry collector to log the spans.

If we look at the lines where I have marked with <<<<<<<<<<, I have expected them to be available in the spans that are published to Sentry but it actually doesn't have them. I thought that the existing calllback handlers were not getting instrumented properly and that's why, the metrics ain't included in the Sentry span at all.

FYI I am currently using traceloop-sdk - 0.23.0 and the relevant OpenTelemetry libraries for instrumentation as shown in the following screenshot:

In addition, I am using the latest versions of langchain -

Thanks @amitjoy this is helpful! Can you try sending out the logs to the console and attach the output here?

[amitjoy]

@nirga I exported the logs to the console:

"traceloop.association.properties.user_id": "test@email.com", is set properly whereas Traceloop.set_association_properties(info.model_dump()) has never been included (refer to the previous comment where I added the python source)

[nirga]

@amitjoy looks like the attributes are there and the problem might be with sentry not showing them. Can you try sending them to some other observability platform like traceloop and verify that?

[amitjoy]

@nirga In the console log, I don't see any property that is part of the aforementioned pydantic model. I believe, they ain't part of the trace.

[amitjoy]

I mean, any property belonging to XInfo pydantic model isn't part of the trace

[nirga]

Oh right! I thought you meant the user_id @amitjoy. I suspect that the reason is that some fields aren't serializable by OpenTelemetry. In general, this is not the intended use of association_properties. You should use then to log things like session_id, or user_id. What you try to do creates a significant load on each span that is sent that may affect performance.

Why do you want to see these? Maybe there's a cleaner way for you to achieve it? (such as - integrating Traceloop + Sentry so that you'll get a link to the Traceloop trace within Sentry containing all the data that you want to log here).

If you still wish to do that - I suggest making sure the dictionary you pass to set_association_properties contain only ints and strings as values. Other values may not be serialzable.

[amitjoy]

@nirga Actually I thought for every LLM completion, the properties as specified in the aforementioned pydantic model are tightly coupled - such as, latency, temperature, token count etc. That's why, I am logging them. I would be really happy if you can provide me with some ideas to log them properly using OpenLLMetry.

The pydantic model comprises these types as of now: int, str, StrEnum, datetime and float. That's why, I have converted the model instance to JSON first and thereafter to dict. I have also removed the elements whose types ain't either int or str. Now, the final dict comprises only int and str types. I tried it and it still doesn't get captured in the console trace.

info_json = info.model_dump_json()
info_dict = json.loads(info_json)

del info_dict['top_p']
del info_dict['temperature']
del info_dict['feedback']

Traceloop.set_association_properties(info_dict)

[amitjoy]

I have debugged traceloop.sdk.tracing.tracing.set_association_properties and for every explicit invocation of Traceloop.set_association_properties(..), it never gets in traceloop.sdk.tracing.tracing._set_association_properties_attributes as it shows that the span is NonRecordingSpan. However, if I add a break point in traceloop.sdk.tracing.tracing._set_association_properties_attributes, it gets executed from elsewhere but not from traceloop.sdk.tracing.tracing.set_association_properties.

It seems that the direct invocation of traceloop.sdk.tracing.tracing.set_association_properties doesn't work as expected.

[nirga]

Oh got it! @amitjoy So looking a the error it seems that you're calling set_association_properties too late - when on_llm_end is called the span is already closed (it depends on the mechanism langchain is using internally to call the callback which might cause the race condition you mentioned).

As I said, this is not the right mechanism for achieving what you're trying to achieve. There are 2 options I can suggest here:

1. Create a custom span yourself. You can create a span in on_llm_start, then in on_llm_end set all the fields that you want as separate attributes, and close the span. This shouldn't be too hard.
2. Wrap the ask method with a @workflow decorator. This will create a span that is guaranteed to stay open when on_llm_end gets called so you should be able to see all the attributes there.

[amitjoy]

@nirga I tried adding workflow decorator to the ask endpoint and now it cannot be processed at all.

{
    "detail": [
        {
            "type": "missing",
            "loc": [
                "query",
                "fn"
            ],
            "msg": "Field required",
            "input": null
        }
    ]
}

from traceloop.sdk.decorators import workflow

@router.get(path="/ask",
            name="Chat Endpoint",
            description="The main endpoint to ask a question to the foundation model",
            summary="Endpoint to ask question",
            tags=["chat", "ask", "chat"])
@rate_limiter(limit=20000, seconds=60)
@workflow
async def ask(request: Request,
              question: str = Annotated[str, Query(title="The question", min_length=1)],
              session_id: str = Annotated[
                  str, Query(title="The session ID", min_length=36, max_length=36, pattern=UUID4_PATTERN)],
              user_id: str = Depends(verify_credentials),
              session_agent: SessionAgent = Depends(lambda: di[SessionAgent])):
...

[amitjoy]

Without the workflow decorator, the endpoint works as expected

[nirga]

Sorry @amitjoy didn't notice it's an async method. You should use aworkflow

[amitjoy]

I tried with aworkflow decorator but the result is the same:

{
    "detail": [
        {
            "type": "missing",
            "loc": [
                "query",
                "fn"
            ],
            "msg": "Field required",
            "input": null
        }
    ]
}

[nirga]

Hmm @amitjoy I think fastapi don't like decorators as they change the method signature. Then I'd build a custom span as I suggested.

[amitjoy]

I will try to create the custom span and will keep you updated. In the meanwhile, could you kindly guide me how you could have achieved it without custom callback handlers? I thought the custom callback handler would help me find the metrics of every call and add them to Otel collector. Do you have any better idea? I would really be very grateful.

[nirga]

Btw we can continue over slack if you want faster responses haha 😅

[nirga]

Chatted offline, there's a bug here around Gemini - for some reason there's no span generated.
