    Hello team, I noticed that there are different exporters in opentelemetry-collector repo and opentelemetry-collector-contrib repo. I'm told that opentelemetry-collector-contrib is a superset of opentelemetry-collector but could someone explain how a collector running from opentelemetry-collector-contrib can use exporters that are only in opentelemetry-collector repo such as zipkinexporter or jaegerexporter?

    We are exploring what it would take to add the nvzFlow protocol to the ecosystem. Are there any examples that would help us better understand what would be involved in doing this?

    hello, I am trying to receive telemetry data as application/json. I am testing with spans first, with a collector configured with otlp http protocol ("localhost:55681"), app agent to export via oltp (same endpoint). When I log out the span (with a collector exporter) I get this message "WARN io.opentelemetry.exporter.otlp.trace.OtlpGrpcSpanExporter - Failed to export spans. Error message: INTERNAL: http2 exception". It works find If export from agent and receive on the collector via otlp grpc. Any help please on what I missed configuring. Thanks

    Hi! what is the best way to install opentelemetry in kubernetes?
    I've found that https://github.com/open-telemetry/opentelemetry-collector/blob/main/examples/k8s/otel-config.yaml but I don't know if there are another tutorial o guide, any advice?

    I'm getting this "append failed" msg, bit confused why is it happening!!

    Hello guys! just a little question
    is there any newer/current performance test result published somewhere?
    https://github.com/open-telemetry/opentelemetry-collector/blob/main/docs/performance.md seems to be bit old and there is also no performance.md in collector-contrib as well.
    Thanks and have a nice day! :)

    Hello! Is there a recommended best practice for how/where to set request-specific tags that we may want to be applied commonly across logs, traces and (in some cases) metrics? For static tags, we can use Resource but it's not clear to me what to use for request-specific tags (e.g. something like enduser.id). Baggage seems like it might be appropriate, but how do I then automatically propagate the baggage tags to the active Span?

    While working on observability for a fleet of IoT devices, I came across many shared paradigms between IoT observability and openTelemetry. With some minor changes, openTelemetry could fit in for logging, traces, and metrics and provide a consistent model for IoT diagnostics too. Has anyone already taken a stab at such an idea?
    I would be glad to discuss it. (Hope I'm posting on the right forum.)

    Is there a way to use files on disk to store context and later extract it to start a new span under the same trace id in OpenTelemetry python? Basically we have a main thread that receives HTTP requests from another service and writes the requests to a disk based queue. These are later picked up by worker threads and I'd like to continue the trace with a new span at this point. However, starting a new span with this context object {'traceparent': '00-2ae64dcf2b8dd14217a42f0cc358d5ce-16a8fc1b04a79a81-01'} just results in a brand new trace/span: SpanContext(trace_id=0x00000000000000000000000000000000, span_id=0x0000000000000000, trace_flags=0x00, trace_state=[], is_remote=False)

    Hi, I have just started looking to use the open telemetry log collector agent which used to be stanza. I am looking at the following repo for the same. https://github.com/open-telemetry/opentelemetry-log-collection. Is there any documentation on how to build it locally and create a local docker image for the same.

    Hi all,
    I'm not trying to solve a particular problem or anything - just doing some research/discovery into Open Telemetry. One of my questions is can I capture trace data using a bytecode/MSIL instrumentation approach (like how DynaTrace OneAgent works, but ideally using an open-source approach/agent) and send this information to an Open Telemetry Collector agent?
    I've asked the question in a lot more detail on Stack Overflow - see https://stackoverflow.com/questions/66486827/bytecode-instrumentation-with-open-telemetry-collector-agent. Apologies in advance if linking to SO is not following the correct protocol on this board - just casting a wider net to hopefully answer my question :)

    Can you help me understand this? If I install the OpenTelemetry Collector do I need to have a jaeger agent running or is it enough that from the application's instrumentation (I use jaeger libraries) it sends it to the opentelemetry collector?

    And another question, if my application only sends traces of jaeger I can deactivate the receivers of prometheus and zipkin and leave only jaeger, right?

    thank you very much

    Hi. I'm new to open-telemetry. Trying to use https://github.com/garthk/opentelemetry_honeycomb#opentelemetryhoneycomb with an elixir app on a kubernetes cluster. Using a config, in config.exs of

    config :opentelemetry,
      processors: [
        otel_batch_processor: %{
          exporter:
            {OpenTelemetry.Honeycomb.Exporter,
             write_key: System.get_env("HONEYCOMB_WRITEKEY"), dataset: "api-telemetry"}
        }

    Should I also be setting an :api_endpoint option? (seen in: https://hexdocs.pm/opentelemetry_honeycomb/OpenTelemetry.Honeycomb.Config.html#t:config_opt/0). Thanks!

    I really like the OTEL collector approach. I think it's a great leap forward in terms of mitigating vendor lock, so thanks to all involved in this project :)
    One thing that I was thinking about is that the company I work for could end up with quite a few OTEL collector agents in our ecosystem - even if we deploy the agent as more of a gateway component... FWIW the company I work for has 3000+ servers/hosts spanning multiple data centers & cloud providers.
    Is there a project for remote config of the OTEL agents e.g. some kind of remote control plane...
    We use Terraform & Ansible, but it could be a bit tricky to manage this in a lot of places - would be nicer to be able to do this centrally from single repo... especially given that the config/policies might vary depending on the host e.g. some we might only want metrics, others we might want logs, metrics, APM...
    What strategies would be suggested. Note: if config management tool like Ansible is the suggested approach, that's fine... just doing some discovery...

    I keep reading that it is recommended to run collector as an agent on the host container and additionally we can run collector as a gateway service as well. It tells me that running the collector as an agent is a must and running the collector as a gateway service is optional?
