Question

Hi all I am new to Signoz Am facing an issue with sending traces to it from python code Signoz `v0 10 2` was deployed on a GKE Autopilot cluster I have added an Ingress each for the frontend 443 gt 3313 and for the collector 80 gt 4318 to access the frontend and the collector over the internet To see if I can send traces I used this code `` and started it like so and did a POST and GET to it as shared in that gist ``` python3 m venv simple server source simple server bin activate python V Python 3 9 13 pip install opentelemetry distro pip install opentelemetry exporter otlp wget OTEL RESOURCE ATTRIBUTES=service name=test apm OTEL EXPORTER OTLP ENDPOINT= http lt sub domain here gt opentelemetry instrument traces exporter otlp proto http python3 simple server py 7000 127 0 0 1``` The traces do not get sent and the logs seem to suggest that I necessarily need to open the GRPC port even though I am specifying `otlp proto http` above Please suggest if I am missing something

Tried the simple flask with a simple standalone docker installation also as shown here to no avail no trace or service shows up in the UI disappointed ``` OTEL RESOURCE ATTRIBUTES=service name=pythonApp OTEL EXPORTER OTLP ENDPOINT= opentelemetry instrument python3 app py```

What s the `OTEL EXPORTER OTLP ENDPOINT= ` Did you meant localhost instead of

Ashijit Pramanik · Answer

No it is the domain where the endpoint is hosted I just redacted it before posting here I also tried it with the public IP address of the VM

Srikanth Chekuri · Answer

Is that address reachable for the app

Ashijit Pramanik · Answer

Yes TCP ports 4317 and 4318 are open to all IPs

Srikanth Chekuri · Answer

Ok port are open but is the host reachable for the app Could you try this troubleshooting guide <https signoz io docs install troubleshooting >

The `troubleshoot` tool seems to have access ```2022 08 31T17 45 55 293+0530 INFO workspace main go 28 STARTING 2022 08 31T17 45 55 293+0530 INFO checkEndpoint checkEndpoint go 41 checking reachability of SigNoz endpoint 2022 08 31T17 45 55 405+0530 INFO workspace main go 46 Successfully sent sample data to signoz ``` I noticed that the flask traces are being sent now though these exceptions also show sometimes ``` OTEL RESOURCE ATTRIBUTES=service name=pythonApp OTEL EXPORTER OTLP ENDPOINT= <http example com 4317> opentelemetry instrument python3 app py 127 0 0 1 31 Aug 2022 13 13 02 POST action HTTP 1 1 500 127 0 0 1 31 Aug 2022 13 13 04 GET completed HTTP 1 1 200 127 0 0 1 31 Aug 2022 13 13 04 GET static assets style css HTTP 1 1 304 127 0 0 1 31 Aug 2022 13 13 04 GET static assets emoji css HTTP 1 1 304 127 0 0 1 31 Aug 2022 13 13 04 GET static assets twemoji min js HTTP 1 1 304 127 0 0 1 31 Aug 2022 13 13 04 GET static assets emoji js HTTP 1 1 304 127 0 0 1 31 Aug 2022 13 13 06 GET list HTTP 1 1 500 127 0 0 1 31 Aug 2022 13 13 06 GET static assets style css HTTP 1 1 304 127 0 0 1 31 Aug 2022 13 13 06 GET static assets emoji css HTTP 1 1 304 127 0 0 1 31 Aug 2022 13 13 06 GET static assets twemoji min js HTTP 1 1 304 127 0 0 1 31 Aug 2022 13 13 06 GET static assets emoji js HTTP 1 1 304 Transient error StatusCode UNAVAILABLE encountered while exporting metrics retrying in Nones Exception while exporting metrics an integer is required got type NoneType Traceback most recent call last File Users username Downloads test apm simple server lib python3 9 site packages opentelemetry exporter otlp proto grpc exporter py line 305 in export self client Export File Users username Downloads test apm simple server lib python3 9 site packages grpc channel py line 946 in call return end unary response blocking state call False None File Users username Downloads test apm simple server lib python3 9 site packages grpc channel py line 849 in end unary response blocking raise InactiveRpcError state grpc channel InactiveRpcError lt InactiveRpcError of RPC that terminated with status = StatusCode UNAVAILABLE details = Connection reset by peer debug error string = created 1661938573 017058000 description Error received from peer ipv4 lt ip address here gt 4317 file src core lib surface call cc file line 967 grpc message Connection reset by peer grpc status 14 gt During handling of the above exception another exception occurred Traceback most recent call last File Users username Downloads test apm simple server lib python3 9 site packages opentelemetry sdk metrics internal export init py line 482 in receive metrics self exporter export metrics data timeout millis=timeout millis File Users username Downloads test apm simple server lib python3 9 site packages opentelemetry exporter otlp proto grpc metric exporter init py line 248 in export return self export metrics data File Users username Downloads test apm simple server lib python3 9 site packages opentelemetry exporter otlp proto grpc exporter py line 345 in export sleep delay TypeError an integer is required got type NoneType ```

Strangely it is still not showing the traces for the previous test code I was trying to run thinking face ``` OTEL RESOURCE ATTRIBUTES=service name=TestApm OTEL EXPORTER OTLP ENDPOINT= <http example com 4317> opentelemetry instrument python3 simple server py 7000 127 0 0 1 HTTP Server Running addrecord one var1 value1 var2 value2 127 0 0 1 31 Aug 2022 17 55 47 POST api v1 addrecord one HTTP 1 1 200 addrecord two var1 value1 var2 value2 var3 value3 127 0 0 1 31 Aug 2022 17 55 50 POST api v1 addrecord two HTTP 1 1 200 127 0 0 1 31 Aug 2022 17 55 54 GET api v1 getrecord one HTTP 1 1 200 getrecord one var1 value1 var2 value2 ```

gt ```python3 simple server py 7000 127 0 0 1``` What does this do Does it have some reload mechanism OTEL It has issues reloader so make sure to disable if that s enabled

<https gist github com dfrankow f91aefd683ece8e696c26e183d696c29> here is the code

Srikanth Chekuri · Answer

There is nothing instrumented so no data is sent What were you expecting The OTEL auto instrumentation only supports some list of popular frameworks <https github com open telemetry opentelemetry python contrib tree main instrumentation>
