Hi all, took a good look around the website for this, didn't find anything. Curious what timeline exists for the first release, eyeing tracing specifically here. I remember it was the second half of 2020, have not seen an update. I manage observability at a firm and am hoping to use tracing for our java and javascript apps as we go deeper into a hybrid cloud scenario.

hello there
can someone help me with EasyCLA, please?
I try to follow this process: https://docs.linuxfoundation.org/lfx/easycla/contributors/corporate-contributor#github
I got the approval from my manager (I got the email) but I am still stuck at the same step in the easycla wizard saying that

Unfortunately, you are not yet approved by the Corporate CLA of Splunk, Inc. on Cloud Native Computing Foundation (CNCF).

any ideas what is wrong?
here are my PRs https://github.com/open-telemetry/opentelemetry-dotnet-instrumentation/pulls/pellared for reference

@pellared yeah, i think your manager has to approve twice

"i see the issue - clicking Approve doesnt actually approve you - i then have to go in and add you manually after I click approve...."

maybe this quote from mine helps your manager :)

@/all , I have some meta-news to share about this Gitter channel!

Per this comment, now that OTel has reached Tracing Spec ≥ 1.0, we are formally moving off of Gitter as the "front door" for OpenTelemetry community chat.

Note that individual SIGs may (and will) continue to use Gitter for their own purposes (see a list here), but general-purpose OpenTelemetry community conversations and/or requests to be directed/redirected from new OTel community members should happen in the CNCF opentelemetry Slack channel, not here.

If you have major concerns, please post them to open-telemetry/community#362 rather than starting that discussion here.

Thank you for reading!

@tedsuo @bhs can you please clarify, do we encourage individual SIGs to move to Slack or we want them to stay on Gitter? My preference would be to move Collector and Log SIGs to Slack (unless the community wants to stay on Gitter).

Hello team, I'm trying to create a Docker image of the otel collector but when I run the command make docker-otelcontribcol, I get the following error

Hello team, I was able to resolve the above issue. But now I'm unable to run the Docker image with my config.yaml file. I run the command docker run otelcontribcol --config path/to/my/config.yaml and I get the following error:

WARNING: unable to read config file: open /path/to/my/config.yaml/config.json: not a directory
Error: cannot load configuration: error loading config file "/path/to/my/config.yaml": open /path/to/my/config.yaml: no such file or directory

For some reason, it adds config.json to my path in the warning, then it tells me that there is no such file /path/to/my/config.yaml when there is. Does anyone know how I can resolve this?

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?

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

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)

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
