08/17/2023, 4:24 AMHi team, when I am using Signoz tracer to monitor a method in my Python FastAPI application which involves jpype library, there is huge numbr of traces coming up on the UI and also the UI hangs on opening up that particular request. Could anyone help me know why this is happening?

08/17/2023, 7:10 AMHow many spans are there?
The community edition supports upto 10k spans in a single trace. The enterprise plan has a feature which allows upto 100k spans in a single trace.

08/17/2023, 7:31 AM@Vishal Sharma 2998 spans coming up. However i have attached traces only to few methods. These many spans showing up when jpype is used.
Other cases only the required number of spans show up.
Is it normal behaviour or something is wrong from my code end?

08/17/2023, 7:32 AMCan you check if the spans are relevant?

Snehanshu Raj
08/17/2023, 7:33 AMNo they are not relevant. they have time spans of 0.01 microseconds.

08/17/2023, 7:33 AMOur enterprise customers do have thousands of spans so depends on your system.

08/17/2023, 7:36 AMIf you see this screenshot, the upload span is the only required span, however the POST/ ones are in huge number coming up.
Snehanshu Raj

08/17/2023, 7:38 AMI didn’t find any relevant github issues on jpype. How did you instrument?

Snehanshu Raj
08/17/2023, 7:39 AMfrom opentelemetry import trace
tracer = trace.get_tracer(name)
with tracer.start_as_current_span("file_response"):

Vishal Sharma
08/17/2023, 7:39 AMSo you are manually instrumenting?
s
Snehanshu Raj
08/17/2023, 7:39 AMYes within each method which i want to be monitored. Usig this.
with tracer.start_as_current_span("file_response"):

08/17/2023, 7:41 AMThere is a nested method calls which comes up perfectly as in the screenshot marked with 7, upload.
Snehanshu Raj
08/17/2023, 7:41 AMHowever i am not able to get why those extra POST spans are showing up.
Snehanshu Raj
08/17/2023, 8:02 AMAlso FYI, the API is being run by the command:
OTEL_RESOURCE_ATTRIBUTES=service.name=autofill_exports OTEL_EXPORTER_OTLP_ENDPOINT="endpoint" opentelemetry-instrument <followed by the api command>

08/17/2023, 9:04 AMAny reason why you are not using auto instrumentation?
s
Snehanshu Raj
08/17/2023, 9:44 AMWhen using auto instrumentation i was not getting spans for individual methods.
Snehanshu Raj
08/17/2023, 9:44 AMOr could you point me to any correct resource?
Snehanshu Raj
08/17/2023, 9:45 AMusing auto instrumentation?

08/17/2023, 9:53 AMhttps://signoz.io/docs/instrumentation/python/
on following this page i was getting only the endpoint span, and this was too in large number. This did not give the spans for the methods it was calling internally.

08/20/2023, 7:32 AM@Vishal Sharma if you could answer this?
