Handling Future Timestamps in Trace Data for Arize

Raja A. · 2024-03-07T15:29:28.614Z

I get the below exception with trying to push trace data to the platform. Detected future timestamp in column 'end_time'. Caution when sending spans with future timestamps. Arize only stores 2 years worth of data. For example, if you sent spans to Arize from 1.5 years ago, and now send spans with timestamps of a year in the future, the oldest 0.5 years will be dropped to maintain the 2 years worth of data requirement.

Raja A. are you trying to send traces to Phoenix or Arize?

to Arize platfom

Kiko C. - Hi Kiko - Any inputs or help ? I am running the app in Ubuntu VM which is hosted in different timezone.

Hi Raja A. is this exception a warning or an error that blocks ingestion? And would you have a notebook/code snippet you could send to us to reproduce? This error is a warning so it shouldn’t block ingestion but just want to confirm
Kiko C.

I can confirm the above message is a warning not an error
Raja A.
·
Kiko C. and Aman K.. I am not able to see the traces. Not sure whether the timestamp is getting messed up somewhere. I am going to take a deeper look and will come back with my findings. Appreciate the response.

Raja A. could you share steps to reproduce the error? Data sample and code?

Hi Raja A., there are a few problems with that code snippet:
1.
I don't know what main() does. Hence I can't evaluate correctness on it
2.
session = px.launch_app() and other lines with px are phoenix logic, but you mentioned you want to send traces to Arize
3.
The model_id you seem to be trying is from one of our tutorials but this is not the logic in them
4.
You are using both LangChainInstrumentator and arize_client.log_spans when they are meant for 2 different things:
a.
You use the instrumentator if you want to log spans 1-by-1, streaming them via OTLP
b.
You use log_spans if you have the spans in a dataframe and want to upload all of them as 1 batch of data

Thanks for this debugging . If there is any code that I can refer to send traces to Arize. please let me know.
